Abstract
The utility model discloses an integrated injection and extraction well head device which is an integrated injection and extraction technology especially applicable in thermal extraction and steam injection of sea and land thick oil fields; and comprises a casing head (1), an tubing head (2), an upper flange (3), a main-diameter combined flat gate valve (6), a side-wing combined gate valve (5) and a throttle valve (5), wherein a double-flashboard polish rod blowout preventer (7) is disposed on the upper part of the main-diameter combined flat gate valve (6), the double-flashboard polish rod blowout preventer (7) is a sealing flashboard (7.2), a lower flashboard is a clamping flashboard (7.4), both the sealing flashboard (7.2) and the clamping flashboard (7.4) are installed in the same shell (7.1), the front end of the sealing flashboard (7.2) is filled with a sealing member (7.3) made by a high temperature resistant organic material and a clamping part on the front end of the clamping flashboard (7.4) is equipped with a slips structure. According to the utility model, an operation of the steam inspection and blowout can be directly changed into an oil pumping operation without changing the well head device or an insulated pipe, the integrated injection and extraction is realized, times for the operation can be decreased greatly and efficiency of the injection and the extraction can be increased.
Description
Technical field
The utility model relates to a kind of notes and adopts integrated well head device, is specially adapted to sea, land viscous crude field thermal recovery steam injection, has the notes of bar producing well to adopt integral process.
Background technology
The on-the-spot thermal recovery well head device using is mainly used in the steam injection operation of heavy crude well at present, after completing, steam injection job execution carries out vexed well, then open flow, after pressure decreased, after changing production wellhead and instlated tubular, there is bar to recover the oil, in order to enhance productivity, reduce operation number of times, new steam process production technology is first by sucker rod pump lower going-into-well before steam injection, after having noted steam, vexed well, open flow, do not change well head and instlated tubular, directly there is bar to recover the oil, therefore need to develop a kind of notes that are applicable to steam injection, oil production technology needs and adopt integrated wellhead assembly.
Summary of the invention:
The utility model object is to provide a kind of notes and adopts integrated well head device, in the situation that not changing wellhead assembly and instlated tubular, can after steam injection operation, directly transfer oil pumping operation to, realizes notes and adopts integrated.
The utility model is achieved in that it is comprised of casing head, tubing head, upper flange, main latus rectum assembled flat gate valve, flank combination gate valve, choke valve, its main latus rectum assembled flat gate valve top is provided with a double disc polish rod anti-blowout device, double ram type preventer upper flashboard is sealing damper, lower flashboard is clamping flashboard, sealing damper, clamping flashboard are installed in same housing, sealing damper front end is equipped with the seal of being made by high temperature resistant organic material, and clamping flashboard front end is equipped with the slips with holding function.During use, successively instlated tubular, sucker rod pump, sucker rod, polished rod are lowered in oil well, install to note and adopt integrated well head device, adjust position of polished rod, open steam injection passage, polished rod is fixedly clamped by clamping flashboard slips, by sealing damper, sealed, now can carry out normal steam injection operation, after completing steam injection, vexed well, open flow operation, polished rod is adjusted to oil pumping position, unclamp clamping flashboard, can carry out sucker rod pumping, sucker rod pumping mainly comprises screw pump oil production and two kinds of modes of oil-well pump.
The utility model can be realized in the situation that not changing wellhead assembly and instlated tubular, can after steam injection, open flow operation, directly transfer oil pumping operation to, and realization notes are adopted integrated, greatly reduce operation number of times, improves to note and adopts efficiency.
