Abstract

The invention discloses a seal integrity device of cement sheath under true triaxial. The seal integrity device of cement sheath under true triaxial comprises a middle main body and a bottom support,the middle main body is fixedly installed at the upper end of the bottom support, a side cover is arranged at the outer end of the middle main body, the middle main body and the side cover are fixedlyconnected through an installation screw, and a middle sleeve is arranged in the middle of the interior of the middle main body. According to the seal integrity device of cement sheath under true triaxial, through an upper hydraulic cylinder at the upper end of the middle main body, an upper pressure cylinder piston is conveniently pushed, in this way, an upper pressure cylinder top plate is effectively driven to press downwards; through a rear hydraulic cylinder at the rear side, so that a rear pressure cylinder piston is conveniently pushed to move, and therefore, a rear pressure cylinder top plate is effectively driven; and through the side hydraulic cylinder at the side edge, a side pressure cylinder piston is conveniently pushed to move, so that the side pressure cylinder top plate iseffectively driven, three-axis fixation is effectively achieved, falling is effectively avoided, sealing of an inner side cement sheath is more convenient, and the overall working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cement sheath, in particular to a cement sheath seal integrity device under true triaxial. Background technique [0002] Cement sheath is a drilling engineering term in the oil drilling and development industry. The cement sheath refers to the cement stone formed by the cement slurry in the annular space. Its function is to wrap the casing hoop to form a ring. After the cementing operation, the casing and the formation are cemented together through the cement sheath (ie cement stone). And when sealing, thus just need to use cement sheath sealing integrity device. [0003] At present, the overall operation of the cement sheath seal integrity device on the market is not very convenient when sealing, and cannot be effectively and comprehensively fixed, so it is not very convenient when sealing, which easily affects the overall production efficiency. Contents of the invention [0004] The purpose of the p...
