Title: Method for determining the level of liquid in a water intake well
Inventor: Denislamov Ildar Zafirovich
IPC: E21B47/047
Filed: 2020-05-12
Granted: 2021-02-02
Abstract: FIELD: gas industry. 
     SUBSTANCE: invention relates to operating water wells using downhole pumping equipment and can be used in the oil industry and in other industries. The method of determining the level of liquid in a water well is based on the difference in the thermal conductivity of the gas medium and the liquid in the well and the different behavior of the electric current conductor in these different environments. Any conductor heats up in a gaseous and liquid medium in different ways, as a result of which its resistance and current strength in the electrical circuit change in different ways. Taking this into account, an electrically conductive single-core cable in a non-conductive sheath with a heat-conductive capacity, folded in two in a U-shape, is placed on a stationary basis in the well from the wellhead to a deep pump or productive formation. The cable is connected through a resistor (electrical resistance) and an ammeter to a series electrical circuit. The well allows determining a calibration dependence of the current in the electric circuit on the level of the gas and liquid media separation. The level of liquid in the well is determined remotely at the required frequency using calibration dependence, connecting an electrical circuit to a voltage source and taking an ammeter reading after a fixed time period. 
     EFFECT: invention determines the level of liquid in a water intake well.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to radiation diagnostics and dentistry, and can be used to predict the development of pain dysfunction of the temporomandibular joint (TMJ) in patients with dentition defects. Computer tomography (CT) of the TMJ is performed in two positions. At the same time, the position of the patient’s lower jaw is determined in the usual occlusion when the dentition is closed to obtain silicone registers. Next, the position of the lower jaw in optimal occlusion is determined by a functional-physiological method with the production of silicone registers. Then a CT scan of the TMJ area is performed in two positions, fixing the position of the lower jaw using two variants of the obtained bite registers and comparing the results of two examinations. At the same time, differences in the width of the articular gap are determined and the probability of developing pain symptoms is predicted by the magnitude of these differences. With a decrease in the width of the articular gap in the upper and posterior parts by 50% or more compared to optimal occlusion, a high probability of the development of a painful symptom is stated.  
     EFFECT: method provides an increase in the accuracy of diagnosis of temporomandibular joint dysfunction in patients with dentition defects without repeated CT by determining the position of the mandibular heads using two bite recorders in one CT session.
