Description
Technical field
The utility model relates to one and exempts from operation steam oil production process pipe string, belongs to oil extraction process tubular column technical field.
Background technology
The existing conventional thermal recovery in oil field will wait after oil well stream-injection stop-spraying, trips out steam injection string and could descend pump to turn to take out, and workload is larger, and easily polluted reservoir shortens application life of pump, also has certain potential safety hazard simultaneously.
Summary of the invention
The purpose of this utility model is the problem existing in order to solve above-mentioned prior art, i.e. conventional thermal recovery will wait after oil well stream-injection stop-spraying, trips out steam injection string and could descend pump to turn to take out, workload is larger,, in the application life of shortening pump, also there is certain potential safety hazard simultaneously in easily polluted reservoir.And then provide one to exempt from operation steam oil production process pipe string.
The purpose of this utility model is achieved through the following technical solutions:
One is exempted from operation steam oil production process pipe string, comprising: abutting unit for sucker rod, protection separator, sleeve pipe, sucker rod, oil pipe or instlated tubular, plunger, valve, casing, one way valve, join vapour pipe nipple, tubing nipple, thermal recovery separator, join and produce dual-purpose valve one, dispensing separator, join and produce dual-purpose valve two and reverse circulation valve, described oil pipe or instlated tubular are arranged on the top in sleeve pipe, between the top of oil pipe or instlated tubular and sleeve pipe, be fixed with protection separator, the top of oil pipe or instlated tubular is provided with abutting unit for sucker rod, on abutting unit for sucker rod, be connected with sucker rod, the lower end of sucker rod is connected with plunger, the lower end of oil pipe or instlated tubular is connected with the upper end of casing, between oil pipe or instlated tubular and casing, be provided with valve, the lower end of casing is connected with the upper end of joining vapour pipe nipple, casing and join between vapour pipe nipple and be provided with one way valve, join the lower end of vapour pipe nipple and the upper end of tubing nipple is connected, between tubing nipple and sleeve pipe, be fixed with thermal recovery separator, the lower end of tubing nipple is connected with reverse circulation valve, with the tubing nipple of oil reservoir one opposite position on be provided with to join and produce dual-purpose valve one, with the tubing nipple of oil reservoir two opposite positions on be provided with to join and produce dual-purpose valve two, between the tubing nipple of position between oil reservoir one and oil reservoir two and sleeve pipe, be fixed with dispensing separator, on the bottom tube wall of described oil pipe or instlated tubular, have steam injection through hole.
The beneficial effects of the utility model are: one, direct swabbing well liquid from oil well after steam soak, having changed conventional thermal recovery will wait after oil well stream-injection stop-spraying, tripping out steam injection string could descend pump to turn the situation of taking out, reduce workload, take full advantage of the favourable oil recovery phase, prevent oil layer pollution, reached the object of Increasing Production and Energy Saving.Two, there is sand control, sand setting, the prolongation pump function in application life.Three, while examining pump, play bleeder effect, and than conventional pump safety and reliability.Four, can realize sand washing, steam injection, turn and take out a tubing string and complete, save a large amount of operation funds.Individual well steam injection-turn and be pumped into merit 1 round, can reduce by 1 thermal recovery operation; Take turns steam injection-turn the process of taking out if complete 2, can reduce by 3 subjobs; Complete 3 and take turns steam injection-turn the process of taking out, can reduce by 5 subjobs.Contrast common process, can shift to an earlier date 3～7 days and turn and take out, thereby increases output.Oil increment is that initial stage daily output is multiplied by 3～7; If calculated by 3 days in advance, initial stage daily output is generally higher, on average press 20t/d calculating, and every steam injection-turn is pumped into merit 1 round can incremental oil production 20 × 3=60 ton; If complete 2 round steam injections-turn the process of taking out, can increase production 20 × 3 × 2=120 ton.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: the present embodiment is implemented under taking technical solutions of the utility model as prerequisite, has provided detailed embodiment, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, the related one of the present embodiment is exempted from operation steam oil production process pipe string, comprise: abutting unit for sucker rod 3, protection separator 4, sleeve pipe 5, sucker rod 6, oil pipe or instlated tubular 7, plunger 8, valve 10, casing 11, one way valve 12, join vapour pipe nipple 13, tubing nipple 14, thermal recovery separator 15, join and produce dual-purpose valve 1, dispensing separator 17, join and produce dual-purpose valve 2 18 and reverse circulation valve 19, described oil pipe or instlated tubular 7 are arranged on the top in sleeve pipe 5, between the top of oil pipe or instlated tubular 7 and sleeve pipe 5, be fixed with protection separator 4, the top of oil pipe or instlated tubular 7 is provided with abutting unit for sucker rod 3, on abutting unit for sucker rod 3, be connected with sucker rod 6, the lower end of sucker rod 6 is connected with plunger 8, the lower end of oil pipe or instlated tubular 7 is connected with the upper end of casing 11, between oil pipe or instlated tubular 7 and casing 11, be provided with valve 10, the lower end of casing 11 is connected with the upper end of joining vapour pipe nipple 13, casing 11 and join and be provided with one way valve 12 between vapour pipe nipple 13, the lower end of joining vapour pipe nipple 13 is connected with the upper end of tubing nipple 14, between tubing nipple 14 and sleeve pipe 5, be fixed with thermal recovery separator 15, the lower end of tubing nipple 14 is connected with reverse circulation valve 19, with the tubing nipple 14 of oil reservoir one opposite position on be provided with to join and produce dual-purpose valve 1, with the tubing nipple 14 of oil reservoir two opposite positions on be provided with to join and produce dual-purpose valve 2 18, between the tubing nipple 14 of position between oil reservoir one and oil reservoir two and sleeve pipe 5, be fixed with dispensing separator 17, on the bottom tube wall of described oil pipe or instlated tubular 7, have steam injection through hole 9.
The length of described plunger 8 is 6～9m.
