Overturning type wellhead testing device

Abstract

The invention discloses an overturning type wellhead testing device, and belongs to wellhead equipment for water injection well testing. The overturning type wellhead testing device is composed of a top pulley, a depressurization plug, a blowout prevention pipe, a fixed rotating body a, a rotating frame and a base. The depressurization plug is fixedly connected with the top of the blowout prevention pipe, and the bottom of the blowout prevention pipe is sequentially connected with a fast-connecting pipe union, a ball valve and the base. The top pulley a lower ladder frame, the fixed rotating body a, a lower pulley and an instrument lock are sequentially arranged on the blowout prevention pipe in a connecting mode from top to bottom. One end of the fixed rotating body a is movably connected with the blowout prevention pipe, the other end of the fixed rotating body a is movably connected with the top end of the rotating frame, and the bottom end of the rotating frame is movably connected with a fixed rotating body b. A lifting rotating handle is hinged to one end of the fixed rotating body b, and the other end of the fixed rotating body b is movably connected with the ball valve. The overturning type wellhead testing device is reasonable in structure. Connection of the fixed rotating body and the blowout prevention pipe is rotary and adjustable and can be adjusted at any time. The blowout prevention pipe can be driven to overturn or turn laterally by operating the rotating frame, and therefore instruments can be taken out from or placed on the ground, and operating workers do not need to climb for working and can finish pipe erection tasks on the ground.

Description

technical field [0001] The invention belongs to a wellhead equipment device for water injection well testing, and specifically relates to a safety and environment-friendly flip-type testing wellhead device which avoids the operation of high-altitude operations and realizes putting instruments on the ground through the flexible application of the device. Background technique [0002] During the whole process of oilfield development, the detection and control of reservoir pressure always plays an important role in the implementation of effective reservoir management. The current well test blowout preventer is more than 2.5 meters above the ground after being erected. Workers need to climb to the top of the blowout preventer with well test instruments and weights to install them. Take out, high labor intensity, low efficiency and relatively high risk, especially in winter, when the weather is cold and slippery, accidents are more likely to occur. In addition, the current test ...
