Description
Technical field
It is particularly a kind of to note gas recovery well reducing completion the present invention relates to oil field gas storage note gas recovery well completion technique field
Method, a kind of or injection-production column jacket used in the method for the note gas recovery well reducing completion.
Background technology
During non-exhausted type oil-gas reservoir gas storage reconstruction, often in two stages：First stage is that gas drive is recovered the oil the stage, in order to
The stable exploitation of gas drive oil recovery is realized, its gas drive gas injection rate at initial stage is relatively low, and durations are longer, for reduction cost of investment, general first
Design uses small size sleeve pipe, and the gas injection productive completion tubing string of supporting reduced size ensures gas injection；Second stage is gas storage
In the stage, to meet the demand of emergency peak regulation, it is typically designed using large scale sleeve pipe, and supporting large-size note gas production productive completion
Tubing string ensures note gas production, and this design method is primarily present the shortcoming of following several respects：
If the 1, gas drive recovers the oil the stage directly using large scale oil pipe and sleeve pipe, higher and very long gas drive mistake is once put into
Journey has made original gas injection oil pipe be damaged, and turns also to need to change a tubing string during exploitation of later stage gas storage, equally causes wave
Take.
If the 2, gas drive recovers the oil the stage using large scale sleeve pipe, small size oil pipe is matched, then occurs that little oil pipe is supported the use
Big packer design, around the stress problem such as dynamic deformation when can increase tubing string gas injection, it is necessary to use small size packer and correspondence note
Gas and oil tubing string, then should use small size sleeve pipe.
Once it can not be changed in stage small casing lower going-into-well if 3, gas drive is recovered the oil, when the later stage switchs to gas storage well, individual well
Certainly will significantly it be adjusted upward with yield, original gas injection oil pipe can not be met with production demand, then needs to dig a well again,
Change large scale sleeve pipe.
In addition original small casing gas injection well needs shut-in well, that is, adds potential safety hazard, also result in waste.
The content of the invention
In order to solve that existing oil field gas storage note gas recovery well completion technique occurs in former and later two stages it is above-mentioned the problem of,
The invention provides a kind of method and injection-production column jacket for noting gas recovery well reducing completion, the method for the note gas recovery well reducing completion can be with
In the case where not digging a well again, that is, the low demand with fluence of gas drive early stage is looked after, can also be completed in the note gas production stage in later stage
Height matches somebody with somebody the demand of fluence.
The technical solution adopted for the present invention to solve the technical problems is：A kind of method for noting gas recovery well reducing completion, bag
