After the pipe column is put into the gas storage reservoir injection and production well, the requirements of quick turn-off and protection of the injection and production well can be met, a circulation channel of fluid in the well is established, the upper part and the lower part of the pipe column are isolated mutually, procedures such as sealing pressure test and packer setting are completed, and technical support is provided for later-stage snubbing operation. The pipe column is matched with the hanging and seating joint, so that the underground electronic pressure gauge can be conveniently fished, the underground dynamic pressure measurement is implemented, and technical measures are provided for the safe operation analysis of the gas storage.
Description
Technical field
The utility model relates to a kind of gas storage and hangs pressure gauge pressure measurement completion tubular column, belongs to gas well completion string technology field.
Background technology
Setting up gas storage is a kind of effective measures of guaranteeing natural gas safety and steady air feed, can regulate the imbalance between supply and demand of summer in winter on the one hand, when accident appears in long-distance transport pipes, can bring into play the effect of emergent air feed on the other hand.Gas storage also is the important leverage of national energy security, has great importance to promoting quick, the safe and orderly development of national petroleum gas business.
Summary of the invention
The purpose of this utility model is to provide a kind of gas storage to hang pressure gauge pressure measurement completion tubular column; this tubing string energy protective casing; turn-off fast the realization down-hole; implement for protection liquid and continuous monitoring bottom pressure, satisfy that the gas storage injection-production column jacket is simple in structure, performance safety, reliable in function and cheaply requirement.
Concrete technical scheme of the present utility model is as follows:
Gas storage hangs pressure gauge pressure measurement completion tubular column from top to bottom by forming with lower member:
Oil pipe+pipe nipple A+ the storm valve that the flows+pipe nipple B+ oil pipe+circulation slide sleeve+oil pipe+grappling seal assembly+hydraulic setting permanent packer+milling exntension tubs+oil pipe+shutoff of flowing is located joint+oil pipe+pipe with holes+suspension and is located joint+horn mouth;
Flow pipe nipple A and mobile pipe nipple B and storm valve with the footpath; Storm valve connects ground control system by liquid controling pipe line; The grappling seal assembly connects the hydraulic setting permanent packer in the insert-seal mode; Suspension is located and is hung downhole electronic pressure bomb in the joint.
After this tubing string is lowered to the gas storage injection-production well, can satisfy that gas field gas storage injection-production well turn-offs fast and the demand of protective casing, can set up the circulation canal of borehole fluid with the circulation slide sleeve of string matching, for all kinds of cycle operations provide condition.Throw stifled blanking plug by steel wire operation and be located the joint in shutoff, can make the tubing string upper and lower part isolated mutually, finish the operations such as sealing pressure testing and packer setting, for the later stage snubbing serving provides technical support.The string matching suspension is located joint and can be made things convenient for the pulling downhole electronic pressure bomb, implements the down-hole dynamic pressure measurement, for the gas storage Safety Operation Analysis provides technical measures.
Description of drawings
Fig. 1 is that gas storage hangs pressure gauge pressure measurement completion tubular column structural representation.
The specific embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
Gas storage hangs pressure gauge pressure measurement completion tubular column from top to bottom by forming such as lower member:
The mobile pipe nipple B13+ oil pipe 1 circulation slide sleeve 4+ oil pipe 1+ grappling seal assembly 5+ hydraulic setting permanent packer 6 milling exntension tubs 7+ oil pipe 1+ shutoff of the mobile pipe nipple A2+ storm valve 3+ of oil pipe 1+ are located joint 8+ oil pipe 1+ pipe 9+ suspension with holes and are located joint 10+ horn mouth 11.
Flow pipe nipple A2 and mobile pipe nipple B13 and storm valve 3 with the footpath, can reduce notes, adopt process mesohigh fluid to the erosion of storm valve 3, prolong the application life of storm valve 3.
By steel wire operation, utilize special tool open and close circulation slide sleeve 4, can realize that oil jacket is communicated with, and reaches the purpose of liquid-circulating in the well.
Utilize the anchor fluke anchoring string of grappling seal assembly 5, and adopt the insert-seal mode to be connected with hydraulic setting permanent packer 6 upper ends, realize the fixing of tubing string, reduce and annotate displacement and the wriggling of adopting tubing string in the process.Realize this packer setting in sleeve pipe by the hydraulic setting mode, realize the purpose of shutoff oil jacket annular space.
In later stage kill-job or the not kill-job well workover process, after hydraulic setting permanent packer 6 top tubing strings trip out, can be lowered to special tool the packing element outer wall of hydraulic setting permanent packer 6 is carried out milling, simultaneously can connect milling exntension tubs 7, hydraulic setting permanent packer 6 and bottom tubing string thereof are tripped out smoothly.
Steel wire operation is lowered to special instrument, can be located joint 8 places in shutoff and realize shutoff in the tubing string, but the fluid,matching compacting shows setting of hydraulic setting permanent packer 6, can be used with circulation slide sleeve 4, sets up liquid-circulating in the well; Also can cooperate operation device under pressure to realize with pressure lower tubular column.
By the steel wire operation mode, downhole electronic pressure bomb 12 instruments such as grade can be lowered to, hang on to hang and be located in the joint 10, realize dynamic pressure measurement and the various functions of downhole instrument, for the gas storage Safety Operation Analysis provides technical measures.After joint 10 shutoff were located in suspension, pipe 9 with holes can be set up down-hole notes, gas production circulation road.
Horn mouth 11 can be reserved larger chamfering in the completion tubular column lower end, be convenient to being lowered to and tripping out in oil pipe of through tubing equipment or equipment.
