Abstract
The utility model discloses a fluid power swelling cone under the shaft. The fluid power swelling cone under the shaft comprises a swelling cone body, wherein a center pipe is fixedly connected into the swelling cone body, four grooves are formed in the swelling cone body, every two of the four grooves are symmetrically formed, and an expansion device is arranged in each groove. By the adoption of the technical scheme, the fluid power swelling cone under the shaft can perform chambering on a cased well and a sand control screen of an open hole and is simple and reliable in structure.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of underground hydraulic expansion cone.
Background technology
Oil well, in oil recovery process, shakes out and easily causes the underproduction, the stopping production of oil well, and the wearing and tearing of aggravation ground and underground equipment, also there will be sand plug, sand to bury phenomenon.Approximately there is 80% sand well employing mechanical means sand control in the whole world, mainly contains sand control pipe sand control, gravel filling sand control etc.Expansion sand control screen is a kind of new sand control technique, and screen expansion, to the borehole wall, can significantly be improved to area of passage, simultaneously can sand production gear is outside at oil pipe.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and a kind of bloat tool that expands sand control screen internal diameter by fluid power is provided, and can be used for the underground hydraulic expansion cone of cased well and open hole well sand control screen ream operation.
For addressing the above problem, the utility model by the following technical solutions: a kind of underground hydraulic expansion cone, comprises the cone body that rises, in the described cone body that rises, be fixedly connected with central tube, the described cone body that rises is provided with four grooves, and four grooves are symmetrical arranged between two, in each groove, are provided with expansion gear;
