Abstract
The utility model relates to a tubing drill for an input well, which mainly solves the problems that prior pipe column under a well is high in sand depositing and salvaging cost and is low in work efficiency. The characteristics of the utility model are that: the upper end and the lower end of a cylinder body(1) are respectively connected to an upper terminal(2) and a cuspate body(3); the upper of the cuspate body(3) is hinged with a unilateral wafer(4) which can be open upward; and the side wall of the upper terminal(2) is provided with a relief valve(5). The tubing drill for an input well has the advantages of simple structure, low cost, convenient use and high work efficiency.
Description
Technical field:
The utility model relates in the oil recovery field, oil field long-pending sand fishing device, especially water injection well sand pumping device in the water injection well down-hole string.
Background technology:
In oil recovery field, oil field, some water injection well causes sand to pile up in down-hole string because of formation sand production, has influenced the normal water filling of water injection well.When this class problem occurring, can only solve by operation in the past, already expend lot of manpower and material resources when doing, operating cost is higher, and operation simultaneously needs the time longer, and inefficiency influences normal water filling.
The utility model content:
Salvage the high and ineffective deficiency of cost in order to overcome in the existing down-hole string long-pending sand, the utility model provides a kind of water injection well sand pumping device, and that this water injection well sand pumping device has is simple in structure, cost is low, the characteristics of easy to use and high efficiency.
The technical solution of the utility model is: this water injection well sand pumping device comprises cylindrical shell, and the upper and lower side of cylindrical shell is connected with top connection and pointed body respectively, and the upper end of pointed body is hinged with the unidirectional disk that can upwardly open, and the sidewall of top connection has pressure-relief valve.
Above-mentioned pressure-relief valve is 4; Pressure-relief valve comprises valve ball, spring and lock nut, and lock nut is a ring bodies, and valve ball, spring and lock nut are contained in the sidewall through hole of top connection successively.
The utlity model has following beneficial effect: owing to take such scheme, this device can directly penetrate in the sand, unidirectional disk is opened, sand enters in the cylindrical shell, on when carrying cylindrical shell, unidirectional disk is closed, seal the cylindrical shell bottom, sand can not spill, and like this, the sand that enters into cylindrical shell will be salvaged ground; If hard sand utilizes pointed body that hard sand is smashed to pieces, mention this device then and transfer fast and get final product.Because be full of water in the down-hole string, in dragging for hard sand process, water can enter in the cylindrical shell, when the hydraulic pressure of cylindrical shell was enough, water can be discharged from pressure-relief valve.This apparatus structure is simple, and cost is low, and is easy to use, avoided operation, high efficiency.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model;
Accompanying drawing 2 is A portion partial enlarged drawings among Fig. 1.
1-cylindrical shell among the figure, 2-top connection, the pointed body of 3-, the unidirectional disk of 4-, 5-pressure-relief valve, 6-valve ball, 7-spring, 8-lock nut.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, the water injection well sand pumping device comprises cylindrical shell 1, the upper and lower side of cylindrical shell 1 is connected with top connection 2 and pointed body 3 respectively, the upper end of pointed body 3 is hinged with the unidirectional disk 4 that can upwardly open, the sidewall of top connection 2 has 4 pressure-relief valves 5, pressure-relief valve 5 comprises valve ball 6, spring 7 and lock nut 8, and lock nut 8 is a ring bodies, and valve ball 6, spring 7 and lock nut 8 are contained in the sidewall through hole of top connection 2 successively.
During actual the use, if the down-hole is soft sand, this device can directly penetrate in the sand, and unidirectional disk 4 is opened, sand enters in the cylindrical shell 1, on when carrying cylindrical shell 1, unidirectional disk 4 is closed, and seals cylindrical shell 1 bottom, sand can not spill, and like this, the sand that enters into cylindrical shell 1 will be salvaged ground; If hard sand utilizes pointed body 3 that hard sand is smashed to pieces, mention this device then and transfer fast and get final product.Because be full of water in the down-hole string, in dragging for hard sand process, water can enter in the cylindrical shell 1, when the hydraulic pressure of cylindrical shell 1 was enough, water can be discharged from pressure-relief valve 5.This apparatus structure is simple, and cost is low, and is easy to use, avoided operation, high efficiency.
