Abstract

The invention discloses a test blowout prevention pipe assembly which comprises a top pulley, an environment-friendly plug, a blowout prevention pipe body, a manual telescopic rod, a ground pulley, anup-lifting pulley block, a test gate and a rotary telescopic mechanism. Thee top pulley and the ground pulley are connected with the blowout prevention pipe body, the environment-friendly plug communicates with one end of the blowout prevention pipe body, the blowout prevention pipe body is connected with the rotary telescopic mechanism in a sliding mode, the up-lifting pulley block is arranged between the rotary telescopic structure and the blowout prevention pipe body, and the rotary telescopic structure can drive the blowout prevention pipe body to rotate, the rotary telescopic mechanism is positioned between the top pulley and the ground pulley, the test gate communicates with the other end of the blowout prevention pipe body, the test gate is connected with the other end of the manual telescopic rod, and the rotation axis of the top pulley is parallel to the rotation axis of the ground pulley. When the test blowout prevention pipe assembly is in use, the up-lifting pulley block and the rotary telescopic mechanism are used for achieving overturning and side rotation of the blowout prevention pipe body, an instrument is taken and put on the ground, and sewage is directionally collected by the environment-friendly plug.

Description

technical field [0001] The invention relates to the technical field of eccentric delamination testing equipment for oilfield water injection wells and its surrounding supporting facilities, in particular to a test blowout preventer assembly. Background technique [0002] In Daqing Oilfield, in the process of eccentric stratification testing of water injection wells, hidden dangers of unsafe accidents such as environmental protection and high-altitude operations have been brought about. It is necessary to pick up and place instruments at high altitudes, and there is a risk of accidents caused by high-altitude falls; sewage from underground pollutes the environment; If the test gate cannot be opened, it will easily cause equipment damage and low work efficiency. It has been threatening the personal safety and environmental protection of the majority of test employees for decades. After continuous efforts, a safety ring type nozzle and no-climbing test nozzle were developed. Th...
