Embodiment Construction

[0023] Attached below figure 1 , figure 2 and image 3 The present invention is described in detail:

[0024] The liquid injection profile logging hydraulic blowout prevention lifting device is mainly composed of a hydraulic lifting mechanism 1, a blowout preventer 2, a grease injection preventer 3, a sky pulley 4, a ground pulley 5, a ground support assembly 6, a union assembly 7, Electric pump assembly 8 etc. are composed of eight major parts.

[0025] The hydraulic lifting mechanism 1 mainly includes a wellhead short connector 10 , a union adapter 11 , a union cap 12 , a lifting sleeve 13 , a lifting bracket 14 , and a ground support component 15 . The lower end of the wellhead short 10 is connected with the Christmas tree 21 through a 2-7 / 8" TBG standard tubing buckle. The left side of the wellhead short 10 is provided with a vent valve 22 for recovering the residual liquid in the blowout preventer 2. The wellhead The upper end of the short connection 10 is provided w...

Abstract

The invention provides a hydraulic blowout prevention lifting device for liquid injection profile well logging.A portable electric pump is used for supplying a power source, and the lifting function of a blowout prevention pipe is achieved through a cooperative action of a lifting support and a cylinder-piston structure.Concentrated stress of the lifting support is avoided by adopting a ground supporting assembly, therefore, the lifting capacity of the lifting support is effectively improved, and it becomes possible that crane operating is replaced by hydraulic blowout prevention pipe lifting.The butt jointing, righting, sealing and tilting functions of the blowout prevention pipe are effectively achieved through a conical surface sealing structure at the joint of a union joint and a wellhead pup joint.The wellhead pollution problem is effectively solved through a minimized fat injecting blowout prevention head structure, the blowout preventing and sealing effects are good, and dynamic sealing and no overflowing can be basically achieved.According to the hydraulic blowout prevention lifting device, the advantages of being simple in structure, small in size and weight, convenient to carry, place and operate, high in safety and reliability and good in overflowing effect are achieved; crane operating can be basically replaced, and therefore a large amount of test cost charge is saved; the good market prospect and economic benefit are achieved.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and relates to a blowout prevention sealing device used for testing, in particular to a hydraulic blowout prevention lifting device used for liquid injection profile logging. Background technique [0002] In the oil production test of the oil field, the downhole data recorded in the fluid injection profile logging must be completed with the help of the wellhead blowout prevention sealing device. Due to the long string of logging tools for fluid injection profiles, the conventional climbing-type artificially-lifted lubricator and the conventional hydraulic blowout preventer lifting device are no longer suitable for the testing needs of such working conditions. At present, most of them use dead cars to assist the blowout prevention sealing device to complete the operation test, which is equipped with many personnel and equipment, high cost, time-consuming and laborious installation a...
