Abstract
The utility model relates to a load displayer for sand prevention. The load displayer for sand prevention is characterized by comprising a shaft core pipe, an upper connector, a lower connector and an elastic claw, wherein one end of the shaft core pipe is in threaded connection with the upper connector, the other end of the shaft core pipe is in threaded connection with the lower connector, the elastic claw is arranged outside the shaft core pipe, one end of the elastic claw is sleeved inside the upper connector, the other end of the elastic claw is in threaded connection with the lower connector, and rotation-preventing pins are arranged in the position where the shaft core pipe is connected with the upper connector and the position where the elastic claw is connected with the lower connector. The load displayer for sand prevention has the advantages that the load displayer for sand prevention is an under-well tool connected with other service tools (a switch tool, a closing tool, a sliding sleeve sealing barrel and the like) for use, and is simple in structure, simple and convenient to operate, safe and reliable, thereby being capable of meeting the requirements for the gravel packing well completion sand-prevention operation.
Description
Technical field
The utility model belongs to the oil field development production technical field, particularly relates to a kind of sand control load display.
Background technology
In the present known oil field development, along with increasing of deep-well, complicated well drilling exploitation, especially the continuous innovation of well-completing process improves, and every function and the use of completion tool are all had higher requirement.Sand control is sand control service aid necessary in the gravel filling sand prevention operation with the load display, and its major function plays tubing string position, location, by on propose service and keep a grip on, elastic claw 60 degree inclined-planes contact with sealing drum, produce and propose demonstration, play positioning action.Therefore traditional load display can't be applicable to the gravel pack completion sand control treatment owing to complex structure, complex operation.
Summary of the invention
The utility model provides a kind of for gravel pack completion sand control field simple in structure, easy and simple to handle and safe and reliable sand control load display for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Sand control load display, comprise axle center pipe, top connection, lower contact and elastic claw, described axle center pipe threaded one end connects top connection, the other end lower contact that is threaded, pipe outside, described axle center is provided with elastic claw, described elastic claw one end is sleeved in the top connection, and the other end is threaded with lower contact, and described axle center pipe all is equipped with the anti-rotation pin with top connection junction, elastic claw and lower contact junction.
The utility model can also adopt following technical scheme:
Described elastic claw one end evenly has several bar shaped gap on axis direction.
Described elastic claw middle part is shaped on boss, and described boss mid portion external surface is the face of cylinder, is the conical surface under the upper end face of boss and the rear surface, and the cone angle of the described upper end conical surface is the obtuse angle, and the cone angle of the described lower end conical surface is acute angle.
Advantage and the good effect that the utlity model has are: this sand control is a kind of and other service aid (switching tools with the load display, closing tool, sliding sleeve sealing drum etc.) connect the down-hole service aid that uses together, before above-mentioned service aid is being gone into the well, need finish pipe arrangement on ground and write down corresponding pipe arrangement size, when above-mentioned service aid is transferred to a certain desired location of down-hole, sand control overcomes pulling force with 60 degree chamferings on the elastic claw of load display mutually with the chamfering of being inverted sealing drum inside, on elastic claw is subjected to, carry or shrink when transferring the power of 5～7T, and by being inverted sealing drum, simultaneously stressed process and size are passed to the load display, and be presented on the instrument of operating desk, thereby determine service aid in the position of transferring of down-hole, clear and definite sliding sleeve switch state.This display device structure is simple, easy and simple to handle and safe and reliable, so can be satisfied with the demand of gravel pack completion sand control treatment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, axle center pipe; 2, anti-rotation pin; 3, top connection; 4, elastic claw; 4-1, bar shaped gap; 4-2, boss; 5, box cupling; 6, lower contact.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, sand control load display, comprise axle center pipe 1, box cupling 5, top connection 3, lower contact 6 and elastic claw 4, described axle center pipe threaded one end connects box cupling 5 and top connection 3, the other end lower contact that is threaded, pipe outside, described axle center is provided with elastic claw, and described elastic claw one end is sleeved in the top connection, the other end is threaded with lower contact, and described axle center pipe all is equipped with anti-rotation pin 2 with top connection junction, elastic claw and lower contact junction.Described anti-rotation pin 2 can prevent from producing circumferential movement between elastic claw, top connection and the lower contact.
Described elastic claw evenly has several bar shaped gap on axis direction, in the present embodiment, described elastic claw one end evenly has 6 bar shaped gap 4-1 on axis direction, make elastic claw when being subjected to the pressure of radial inward, and its external diameter produces and shrinks.Described elastic claw middle part is shaped on boss 4-2, described boss mid portion external surface is the face of cylinder, it is the conical surface under the upper end face of boss and the rear surface, the cone angle of the described upper end conical surface is the obtuse angle, when running into the little instrument of internal diameter, resistance is bigger, need execute certain axial tension that adds, and could pass through.The cone angle of the described lower end conical surface is acute angle, and when running into the little instrument of internal diameter, resistance is less, can pass through smoothly.
This sand control is a kind of and other service aid (switching tools with the load display, closing tool, sliding sleeve sealing drum etc.) connect the down-hole service aid that uses together, before above-mentioned service aid is being gone into the well, need finish pipe arrangement on ground and write down corresponding pipe arrangement size, when above-mentioned service aid is transferred to a certain desired location of down-hole, sand control overcomes pulling force with 60 degree chamferings on the elastic claw 4 of load display mutually with the chamfering of being inverted sealing drum inside, on elastic claw is subjected to, carry or shrink when transferring the power of 5～7T, and by being inverted sealing drum, simultaneously stressed process and size are passed to the load display, and be presented on the instrument of operating desk, thereby determine service aid in the position of transferring of down-hole, clear and definite sliding sleeve switch state.
Be lowered in the outer tubing string of sand control, when sand control passes through in the sealing drum with the load display, elastic claw 4 is subjected to seal compression to begin to shrink, to compress stressed process and size simultaneously transmits and is presented on the instrument of operating desk, thereby determine instrument in the position of transferring of down-hole, clear and definite sliding sleeve switch state.
This sand control is with loading the display elastic claw under the situation that is subjected to certain axial tension or pressure, external diameter produces and shrinks, during by the less instrument of internal diameter, simultaneously stressed process and size are transmitted and be presented on the instrument of operating desk, thereby determine that instrument is in the position of transferring of down-hole.
