Embodiment Construction

[0011]In the figure: a hydraulic spraying device includes a connecting cylinder, a fully sealed blowout preventer 11 and a half sealed blowout preventer 1. The connecting cylinder includes a circular cylinder 7 and a cone-shaped cylinder 10 . The circular cylinder has a double-flange structure, that is, the two cylinder mouths of the circular cylinder, one is the upper cylinder mouth, the other is the lower cylinder mouth, the upper cylinder mouth and the lower cylinder mouth are respectively flange structures, and bolt holes are evenly distributed on the flange structures; There are outwardly protruding spraying connection ports 8 on the circular cylinder, and there are four spraying connection ports, which are opposite to each other to form two pairs of spraying connection ports, that is, one pair is the front and rear sides of the circular cylinder. Connecting port, the other pair is the spraying connection port on the left side and the right side of the circular cylinder. ...

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...
