Hydraulic rush spray device

Abstract

The invention discloses a hydraulic rush spray device. The hydraulic rush spray device aims at solving the problems of leakage and blowout of a Christmas tree, the detects are overcome that an existing oil well rush spray device has difficulty in timely, effective and complete controlling, and the number of accidents can be effectively controlled to be minimum, so that loss is minimum; when the Christmas tree leaks and generates blowout, the whole control device covers the Christmas tree; the device is a hydraulic driving whole-sealing blowout preventer, a hydraulic driving semi-sealing blowout preventer is arranged on the lower portion of the device, the hydraulic driving semi-sealing blowout preventer seals a well mouth sleeve, a connection cylinder which connects an upper blowout preventer and a lower blowout preventer is arranged on the middle portion of the device, blowout prevention connection openings are formed in two sides of the connection cylinder, and the blowout preventeradopts a rubber core with high temperature resistance; the hydraulic rush spray device can timely, effectively and completely control leakage and blowout of the Christmas tree, the number of the accidents can be effectively controlled to be minimum, so that the loss is minimum, the device is resistant to high temperature, and blowout prevention and well killing operation can be conducted.

Description

technical field [0001] The invention relates to an oil well rush spraying device, in particular to a hydraulic spray spraying device. Background technique [0002] At present, many technologies and various devices are used in oil well rush blowout in oil fields. The Patent Office of the State Intellectual Property Office has successively announced the invention patents of the "oil well blowout rooting method and mechanism" of the patent number "2012104328321", the "oil well rapid blowout device" of "2013102061039", and the "oil well blowout device" of "201110318655X" . The invention patent of the rooting method and mechanism of oil well spraying is to solve the problem that the rooting technology of the existing oil well spraying device cannot be applied to wells whose casing heads are not exposed to the ground; the rooting method and mechanism of oil well spraying provide A rooting method for oil well spraying and a rooting mechanism used therefor are disclosed, and relat...

AI Technical Summary

Problems solved by technology

However, in view of the leakage of the Christmas tree and the occurrence of blowout, it is difficult for the current oil well blowout device to control it in a timely, effective and complete manner.

During normal oil production, the Christmas tree can protect the wellhead, but because some trees are under pressure for a long time during operation, the internal structure is prone to change. Once a blowout accident occurs due to leakage, harmful gases will pose a great threat to life and property. The environment causes pollution. At present, there is no device that can effectively control accidents to a minimum and minimize losses.
