Description
Technical Field
The utility model relates to a strainer technical field specifically is a sand control strainer that can be used to powder fine sand stratum geothermal well.
Background
The development process of hydrothermal geothermal resources usually needs to dig a well and put into a submersible pump to take water for utilization, if the geothermal water contains a large amount of sand grains, the submersible pump and geothermal water utilization equipment are blocked or seriously damaged, and therefore strict sand prevention is needed in the well forming process.
The sand control water filter pipe for the geothermal well in the fine sand stratum is provided to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a can be used to sand control strainer of powder fine sand stratum geothermal well has solved the sand control and needs to throw the gravel, if throw the gravel and block up in the canopy, cause the problem of mud play sand very easily.
In order to achieve the above purpose, the utility model provides a following technical scheme: a sand prevention strainer pipe for a ground heat well in a fine sand stratum comprises a strainer pipe, wherein a female buckle is arranged at the top of the inner side of the strainer pipe, and a male buckle is arranged at the bottom of the outer surface of the strainer pipe;
the surface fixed mounting of strainer has the inlayer cage, one side fixed mounting that the strainer was kept away from to the inlayer cage has outer cage, the inboard of outer cage and inlayer cage is provided with the filter material.
Further, the strainer is processed by a petroleum casing pipe, the steel grade of the petroleum casing pipe is J55, and the specification is 177.8 multiplied by 8.05mm.
Further, outer cage and inlayer cage are trapezoidal silk lantern ring, the interval between outer cage and the inlayer cage is 5cm.
Further, the filter material is quartz gravel, quartz gravel's particle size is 2mm.
Furthermore, round holes are formed in the periphery of the outer surface of the water filtering pipe, and the diameter of each round hole is 4cm.
Compared with the prior art, the technical scheme of the application has the following beneficial effects:
this sand control strainer that can be used to ground fine sand stratum geothermal well, strainer and the poor sandstone one-to-one of cemented degree during the construction, strainer accessible box and pin thread link to each other with the oil casing, go into the well down, permeate water strongly, need not throw the gravel material sand control, and drilling aperture requirement is little during the construction, practices thrift construction cost and cycle.
