For several decades, the problem of increasing oil recovery from reservoirs has been one of the most significant in oil-producing countries of the world. Most oil fields, usually represented by heterogeneous reservoirs, are developed using a waterflooding system.
Experience in the development of water-oil zones shows that oil extraction from deposits underlain by bottom water is characterized by a relatively low oil recovery factor. When monitoring the development of oil and gas fields, various research methods are used. One of the main research methods is hydrodynamic testing of wells (HDT). The article discusses the influence of the skin factor on well productivity.

Respublikanın neft hasilatını artırmaq üçün ən praktik üsul mövcud yataqlarda neft hasilatının intensivləşdirilməsidir, çünki məlumdur ki, hazırda istifadədə olan yataqlardan əlavə yeni, perspektivli yataqlar hələ kəşf olunmamışdır. Digər strategiyalarla və üsullarla yanaşı, yeni quyuların qazılması istər dəniz, istərsə də quru sahələrdə yerləşən yataqlardan neft ehtiyatlarının çıxarılmasında hələ də ən vacib addımlardan biridir. Bu günə qədər respublikanın quru yataqlarından 1 mlrd. t neft hasil edilmişdir ki, bu da qurudakı neft ehtiyatlarının yalnız 40%-i deməkdir. Neft ehtiyatlarının qalan 60%-nin çıxarılması ilə bağlı problemlər hələ də öz aktuallığını qoruyub saxlayır.
Əsas problemlər qalıq neftlərin daha çox udulmağa meyilli zonalarda və enerjisi tükənmiş yataqlarda olmasından irəli gəlir. Belə neftin çıxarılmasının əsas üsulu köhnə laylara yeni quyuların qazılmasıdır. Lakin enerjisi tükənmiş yataqlarda qazma işi aparmağın da bir sıra çətinlikləri vardır. Bu problemlərdən biri qazma məhlulunun udulmasıdır. Bildiyimiz kimi, laydan neft hasil etdikcə layın təzyiqi düşür və layın enerjisi azalır, bu azalma layın yarılma gradientinə də təsir göstərir. Nəticə olaraq enerjisi tükənmiş layların yarılma gradienti də azalır və qazma zamanı, qazma məhlulunun təzyiqi nəticəsində layda yarılmalar olur, bu da qazma məhlulunun itkisinə (udulmasına) səbəb olur. Qazma mayesinin udulması qazma ilə bağlı ən çətin mürəkkəbləşmələrdən biridir. Lay təzyiqinin azalması ilə yanaşı, qazma mayesinin udulmasının müxtəlif səbəbləri olur. Bunların bir neçə səbəbi ola bilər, məsələn, öncədən bilinən lay çatları, yüksək hidrostatik təzyiqin yaratdığı hidravlik qırılmalar, layların yüksək məsaməliliyi, drenaja məruz qalma, aşağı lay təzyiqi zonalar, uzunmüddətli istismar, qazma prosesində texnoloji rejimin pozulması və s.

Qaldırıb-endirmə əməliyyatları quyuların qazılmasının texnoloji dövrünün mühüm hissəsini təşkil edir, çünki quyu dərinləşdikcə texnoloji proses getdikcə daha dərin yeraltı horizontlara keçir və onunla birlikdə texnoloji avadanlıq hər qazma işinin sonunda quyudan çıxarılır və yeni bir reysda dərinləşməyə davam etmək üçün quyuya endirilir. Mərmilərin yapışmasını və bərkidilməsini aradan qaldırmaq və bəzi hallarda qazma prosesi zamanı həddindən artıq ox yükünü aradan qaldırmaq üçün səyyar qazma qurğusunun qaldırıb endirən mexanizmi istifadə olunur. Buna görə də, yük qabiliyyəti, dinamik etibarlılıq və istismar rahatlığı baxımından ona artan tələblər qoyulur.

NEFT-QAZ QUYULARININ QORUYUCU KƏMƏRLƏRLƏ QAZILMASI TEXNOLOGİYASININ ÜSTÜNLÜKLƏRİNİN NƏZƏRDƏN KEÇİRİLMƏSİ

Published: July 2024

Qoruyucu kəmərlərlə qazma quyunun eyni zamanda həm qazıldığı həm də qoruyucu kəmərin quyuya endirildiyi bir prosesdir. Bu yeni texnologiya son illərdə uğurla tətbiq olunur. Qoruyucu kəmərlə qazma texnologiyasının inkişaf etdirilməsinin əsas məqsədi qazma borusunun əlavə olunması və qoruyucu kəmərin endirilməsi ilə əlaqəli Qeyri Məhsuldar Vaxtı (QMV) aradan qaldırılması idi (1). Bununla belə, texnologiyanın erkən tətbiqi zamanı böyük diametrli qoruyucu kəmərlə qazma zamanı digər üstünlüklər də müşahidə edilmişdir. Bu məqalədə bu üstünlüklərdən dördü nəzərdən keçirilir, bunlar udulmanın (maye dövranının itməsinin) azaldılması, quyu divarının möhkəmliyi, quyunun daha dayanıqlı olması və qazma prosesinin təsiri ilə lay zədələnməsinin (əsasən də keçiriciliyin) azaldılmasıdır. (2,7,8).
Qoruyucu kəmərlə qazma iki yolla qazma məhlulunun laya itkisini azaldır. Bunlardan biri olan suvaq effekti (plastering effect) açıq quyu lüləsinin divarını bərkidir, keçiriciliyi azaldır və açıq quyu lüləsi ilə lay arasında qazma məhlulu ötürülməsinin qarşısını alır. Belə ki, qazıma boruları ilə qazıma zamanı boruarxası fəzanın diametri böyük olur, qoruyucu kəmərlərlə qazımada isə boruarxası fəza kiçik olur. Qoruyucu kəmər fırlanan zaman şlamlar quyu divarına sürtünərək lay məsamələrini bağlayır və bunun nəticəsində qazma məhlulunun udulmasını azaldır. Bunlardan əlavə quyu divarının dayanıqlığı və sementləmənin keyfiyyətini artırmış olur. Nəticədə udulma gözlənilən yerlərdə bu yeni texnologiya özünü doğrultmuş olur. Qazma zamanı məhlul itkilərini aradan qaldırmaq mümkün olmayan hallarda, qazma prosesi qoruyucu kəmər ümumi dərinliyə çatana qədər minimum itkilərlə davam etdirilə bilər. Məhsuldar laya qazma məhlulu itkisinin azalması, layın keçiriciliyinə zərər vura bilməyəcək. Bu, məhsuldar laya qazılmış quyuların istismarı zamanı məhsuldarlığının daha çox olmasına səbəb olur.
Qazılan süxur parçaları quyu divarında keçirici olmayan gil qabığı əmələ gətirdiyi üçün quyuda təzyiqin saxlanması artır. Bu proses quyu lüləsi ətrafında layın qırılma qradiyentini artırır və nəticədə daha geniş əməliyyat qazma məhlulu çəkisi pəncərəsi əldə edilir. Sabitlik problemi olan quyular qoruyucu kəmər ilə problemsiz qazıla bilər.
Bütün qeyd olunan üstünlükləri ilə qoruyucu kəmər ilə qazma qazma sənayesinin gələcəyinə gedən yolu müjdələyir. Müzakirə olunan üstünlüklərin hər birini əldə etmək üçün bir çox qazma təcrübələri hazırlanmışdır.

Valves are devices that are installed in pipelines, used devices and change cross-sections and regulate the flow of liquid or gas. Valves are divided into a number of types depending on the purpose of use: connecting-regulating, regulating, protective, special. The ball valve belongs to the group of connecting and regulating valves. Other valves, including the ball valve, consist of three main parts. These parts are the body, the transmission and the working body. In terms of body structure, they are of two types: straight and angled. In models with a straight body, the direction of flow at the inlet and outlet remains the same, while in angled models the direction can change up to 90°.
Valves are drawers, valves, taps, etc. There are many types. One of the most common types are stopcocks. Shutoff valves are used in the oil and gas industry to prevent open gushing when drilling wells or to completely shut off the pipe channel when decommissioning wells. Mixers have the ability to create high volume. Mixers have become widespread due to their small size and low flow resistance. Disadvantages include difficult rotation as the diameter increases and riveting at high temperatures. Faucets come in spherical, conical, and cylindrical, depending on the plug design.
The valve strength report determines the safety margin and stress of the valve parts. The power due to the valve force, friction force between the moving parts of the valve, axial force, etc. must be determined.
Keywords: valves, valve, ball valve, ball valve, power metering, plug connection.
SELECTION OF AN EFFICIENT TRANSPORTATION PROCESS OF VERY HIGH VISCOSITY AND HEAVY OILS AND INVESTIGATION OF RESULTING COMPLICATIONS

Published: July 2024

The article discusses the investigation of the difficulties that arise during the transportation of very high viscosity crude oils and the features of the transportation process. Among high-viscosity oils in Azerbaijan, "Muradkhanli" oil can be mentioned. Special attention is paid to the rheologically complex behavior processes of such crude oils. In general, the storage and transportation of very high viscosity oils has been and remains a complex process for oil producing countries around the world. Heavy and highly viscous crudes are thick and sludgy, so they resist flow through pipelines during transport and are often transported by truck or rail, adding significant costs and potential hazards. Pipeline transportation of oils is also hampered by asphaltene and paraffin precipitation, formation water and salt content, and corrosion problems. Of course, each of these cases should be taken into account. There are various ways to improve this process (by heating, by adding depressants with different reagent composition, etc.).
Keywords: high viscosity, heavy crude oil, depressant, railway-transportation, oil crystallization.

The research results show that before the 20th century, Cirebon did not have any government-managed sewers at all. Therefore, city residents build sewers independently or use the surrounding environment to dispose of sewage and household waste. Construction of drainage channels and river normalization in Cirebon began in 1885 and peaked from 1918 to 1934. The development project was divided into South Cirebon and North Cirebon. The presence of sewers gave rise to toilet facilities in Cirebon City and developments in waste management.
