Abstract
The no killing well well head operating equipment that the utility model provides a kind of note to adopt integrated thermal recovery technology, wherein no killing well wellhead equipment, comprise big four, steam injection well head first cover, hollow stem hanger, by master valve and steam injection well head, first overlaps and is connected in described big four upper end, and described hollow stem hanger is arranged on big four inside.When described hollow stem hanger is used for steam injection, make band pump hollow stem connect a hollow pole socket hanging joint seat and hang on hollow stem hanger, hollow stem hanger latus rectum is no more than master valve latus rectum.The utility model can solve thermal recovery complete note well no killing well well head play lower beam again can the requirement of meeting tier 2 well control.
Description
Technical field
The utility model relates to oil-field thick-oil thermal production well note and adopts integrated thermal recovery technology field of operation, and specifically a kind of note adopts the no killing well well head operating equipment of integrated thermal recovery technology.
Background technology
It is adopt note to adopt integrated insert pump and supporting pipe bar combine that note adopts integrated thermal recovery technology, and use one-trip string realizes two activitiess of steam injection and oil recovery, that is: turn-week, turn take out all motionless steam injection string.Current note is adopted integrated thermal recovery technology and be there is two problems: one is to realize snubbing serving completely.Current note adopt integrated thermal recovery technology band infusion vapour shaft collar from bottom to top (as shown in Figure 1) be: big four x1, gate x31, hollow stem hanger x2, gate x32, steam injection well head first cover x4.During steam injection, hollow stem (band pump) connects a hollow pole socket hanging joint seat and hangs on hollow stem hanger, and steam injection needs after boiling in a covered pot over a slow fire well to remove hollow stem hanger and above wellhead component thereof, and carries out removing hollow stem completion.It can not be made to close because hollow stem runs through gate x31, and wellheadpressure.Therefore, tear well head open and turn smoke lower hollow stem before need to carry out steam injection string and fill with hydraulic pressure well and meet the requirement of one-level well control, low temperature working fluid formation can cause cooling injury; For the well that pressure after stewing well open flow is high, the stewing well time need be extended, affect oil production efficiency, even carry out whole pit shaft kill-job, cause stratum cold damage; Two is do not have the measure of secondary well control.To remove in hollow stem process once there is gas blowout accident by uncontrollable, well control requirement can not be met.
Summary of the invention
The purpose of this utility model is the no killing well well head operating equipment providing a kind of note to adopt integrated thermal recovery technology, can solve thermal recovery complete note well no killing well well head play lower beam again can the requirement of meeting tier 2 well control.
The purpose of this utility model realizes by one of following technical measures:
The no killing well steam injection wellhead equipment that this note adopts integrated thermal recovery technology comprises big four, steam injection well head first cover, hollow stem hanger, by master valve and steam injection well head, first overlaps and is connected in described big four upper end, and described hollow stem hanger is arranged on big four inside.
The purpose of this utility model also realizes by one of following technical measures::
When described hollow stem hanger is used for steam injection, make band pump hollow stem connect a hollow pole socket hanging joint seat and hang on hollow stem hanger, hollow stem hanger latus rectum is no more than master valve latus rectum.
The purpose of this utility model realizes by following technical measures two:
The no killing well steam injection wellhead equipment that this note adopts integrated thermal recovery technology comprises big four, also comprise thick oil thermal extraction hollow rod blowout-preventing device, described big four upper end is connected with the threeway of band gate by master valve, described band gate threeway connects the thick oil thermal extraction hollow rod blowout-preventing device of top, and described hollow stem hanger is arranged on big four inside.
The purpose of this utility model also realizes by following technical measures two:
Described thick oil thermal extraction hollow rod blowout-preventing device at least arranges two, uses tubes connection each other.
The purpose of this utility model is realized by following technical measures three:
The no killing well steam injection wellhead equipment that this note adopts integrated thermal recovery technology comprises big four, also comprise thick oil thermal extraction hollow rod blowout-preventing device, polished rod sealer, described big four upper end is connected with the threeway of band gate by master valve, described band gate threeway connects the thick oil thermal extraction hollow rod blowout-preventing device of top, described thick oil thermal extraction hollow rod blowout-preventing device upper end connects polished rod sealer, and described hollow stem hanger is arranged on big four inside.
Compared to prior art, the utility model has following beneficial effect:
Achieve the no killing well well head operation that a kind of note adopts integrated thermal recovery technology, not only meet note to adopt integrated thermal recovery technology and play secondary well control requirement in lower beam process, and reach snubbing serving, avoiding one-level well control to wash kill-job causes hollow stem to cool the object of injury and stratum cold damage, and economic benefit is huge.
