Description
Technical field
The present invention relates to oil-field thick-oil thermal production well note and adopt integration thermal recovery technology field of operation, specifically a kind of note adopts one
The no killing well well head operating procedure of body heat-transformation excavating technology and equipment.
Background technology
It is to use note to adopt integration insert pump to combine with supporting tube rod that note adopts integration thermal recovery technology, uses one-trip string real
Existing steam injection and two technical processs of oil recovery, it may be assumed that turn-week, turn and take out the most motionless steam injection string.Note adopts integration thermal recovery at present
There are two problems in technique: one is to realize snubbing serving completely.Current note adopts integration thermal recovery technology band pump
Steam injection shaft collar is from bottom to top (as shown in Figure 1): big four x1, gate x31, hollow stem hanger x2, lock
Door x32, steam injection well head upper half set x4.During steam injection, hollow stem (band pump) connects a hollow pole socket hanging joint seat and hangs over sky
On core bar hanger, 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 sky
Core bar completion.It can not be made to close owing to hollow stem runs through gate x31, and wellheadpressure.Therefore, tear well head open and take out with turning
Needing to carry out steam injection string liquid filling kill-job before removing hollow stem and meet one-level well control requirement, stratum can be caused cold by low temperature working fluid
But injure；For the well that pressure after stewing well open flow is high, the stewing well time need to be extended, affect oil production efficiency, even carry out whole well
Cylinder kill-job, causes stratum cold damage；Two is not have two grades of well control measures.Blowout thing is once there is during removing hollow stem
Therefore by uncontrollable, it is impossible to meet well control requirement.For solving problem above, design has been invented note and has been adopted integration thermal recovery technology
No killing well well head operating procedure.
Through retrieval, do not have to find the open source literature as the present invention.
Summary of the invention
