Title: Method for trenchless construction of trunk pipeline length under obstacle
Inventor: MINAEV VSEVOLOD IOAKIMOVICH
IPC: E02F5/18
Filed: 1996-11-10
Granted: 1999-03-10
Abstract: FIELD: pipeline laying technology. SUBSTANCE: according to method, operations are started with driving curvilinear bore-hole under obstacle. Diameter of this bore-hole is at least 1.1 times larger than diameter of pipeline length to be constructed. Successively introduced into bore-hole are preliminarily curved sections of pipeline being constructed. Each section of pipeline being constructed is bent in at least two points. Created in process of bending is at least one middle part of section of rectilinear configuration and two extreme parts of rectilinear configuration. Length of each extreme part of pipeline section is equal to half of length of middle part of this section. Longitudinal axes of symmetry of all parts of each section of pipeline being constructed are located in common plane. Sections of pipeline being constructed as they are being introduced into bore-hole are rigidly connected to each other. Application of aforesaid method allows for shorter periods of construction of pipeline length under obstacle and for its higher operating reliability. EFFECT: higher efficiency. 1 cl, 3 dwg

Abstract: Устройство для отворачивания труб в скважине относится к области нефтегазодобычи, а именно к буровой технике, и может быть использовано при ликвидации аварий, связанных с прихватом труб в скважинах во время их бурения или ремонта. Устройство содержит полый шток и гидравлический якорь, установленный с возможностью осевого перемещения его корпуса на полом штоке. Механизм преобразования движения выполнен в виде передачи винт - гайка с возможностью взаимодействия с корпусом и ловителем. Винт жестко соединен с полым штоком, а гайка снабжена обгонной муфтой, выполненной с возможностью передачи вращательного момента на корпус. Гидравлический якорь и ловитель соединены между собой установочным кожухом с возможностью вращательного и принудительного осевого перемещения. Ловитель выполнен в виде гидравлического якоря, размещенного на полом штоке с возможностью осевого перемещения. Устройство спускают в скважину и устанавливают гидравлический якорь против одной обсадной трубы, а ловитель - против другой. При поднятии давления в полом штоке плашки якоря и ловителя входят в зацепление с обсадными трубами. Поднятием колонны насосно-компрессорных труб (НКТ), связанной с полым валом, вращают гайку винтом. Это ведет к вращению - отворачиванию верхней трубы. Обгонная муфта позволяет вернуть винт спуском НКТ в исходное положение.
