Abstract
The utility model relates to the technical field of well completion equipment, in particular to a fracturing sliding sleeve with an elastic sleeve ball seat. The prior art has the problems that the efficiency is low, the consumed time is long, and the number of fracturing stages is substantially restricted. To solve the problems, the utility model provides the following technical scheme: the fracturing sliding sleeve with the elastic sleeve ball seat comprises a sliding sleeve housing and a slider arranged in the sliding sleeve housing, wherein the slider and the housing are connected by a shear pin; the sliding sleeve housing is also provided with the elastic sleeve ball seat inside; the slider and the elastic sleeve ball seat are in threaded connection, and the slider is arranged above the elastic sleeve ball seat; and the inner surface of the sliding sleeve housing is provided with a groove, and the groove is formed below the elastic sleeve ball seat. By adopting the fracturing sliding sleeve with the elastic sleeve ball seat, provided by the utility model, the well completion efficiency is improved, and the time is saved.
Description
Technical field:
The utility model relates to the completion equipment technical field, is specifically related to a kind of fracturing sliding bush with the resilient sleeve ball seat.
Background technology:
Along with the demand of increasing horizontal well multi-region pressure break, many fracturing technique of having arisen at the historic moment.Efficient is hanged down and the problem of length consuming time yet the restrictions because water is developed such as existing fracturing technique such as bridging plug, these technology of while also show.Although common pitching drives the sliding sleeve fracturing technology in existing technical certain improvement that obtained, " common pitching drives the sliding sleeve fracturing technology " equipment refers to: whole ball seat is connected with sliding part, be connected by shear pin between sliding part and the shell, these parts have formed a fracturing sliding bush.Fracturing process: at present, every one-level only has a fracturing sliding bush, and the area of pressure break is very limited.In order to increase the pressure break area, have to increase progression.But horizontal well depth is limited, so progression just is restricted.So just cause low, the consuming time length of efficient, the problem that concurrent fracturing progression is significantly limited.
The utility model content
The purpose of this utility model provides a kind of fracturing sliding bush with the resilient sleeve ball seat, the problem that is significantly limited to overcome low, the consuming time length of efficient that prior art exists and pressure break progression.
For achieving the above object, the technical scheme that the utility model provides is: a kind of fracturing sliding bush with the resilient sleeve ball seat, comprise the sliding sleeve shell and be arranged at the interior sliding part of sliding sleeve shell, be connected by shear pin between sliding part and the shell, its special character is: also be provided with the resilient sleeve ball seat in the sliding sleeve shell, be threaded connection between described sliding part and the resilient sleeve ball seat and sliding part is arranged at the top of resilient sleeve ball seat, the inner surface of described sliding sleeve shell is provided with groove, and groove is arranged at the below of resilient sleeve ball seat.
Be equipped with sealing ring between above-mentioned sliding part and the sliding sleeve shell and between resilient sleeve ball seat and the sliding sleeve shell.
Above-mentioned screw thread is trapezoidal thread.
The utility model has following advantage and effect with respect to prior art:
1. the utility model fracturing sliding bush can form systems and uses with a plurality of the linking together of one-level, thereby realizes finishing open operation with a plurality of fracturing sliding bushs of one-level with a ball, improves completion efficiency and saves time;
2. the utility model also is applicable to open hole well and the joint that improves the tubing string internal pressure, and this joint can be installed in the optional position of tubing string;
3. simple and reliable design only has one group of shear pin;
4. the utility model does not need to pump into bridging plug and perforating gun, has saved a large amount of water resources;
Description of drawings:
Fig. 1 is the structural representation before the utility model action;
Fig. 2 is the structural representation after the utility model action;
Fig. 3 is the structural representation of resilient sleeve ball seat;
Fig. 4 is that the A of resilient sleeve ball seat is to schematic diagram;
Wherein, 1-sliding part, 2-sliding part sealing ring, 3-screw thread, 4-resilient sleeve ball seat, 5-ball seat lower seal, sealing ring on the 6-ball seat, 7-sliding sleeve shell, 8-groove, 9-shear pin, 10-pressure break ball.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated.
With reference to Fig. 1, Fig. 3, Fig. 4, a kind of fracturing sliding bush with the resilient sleeve ball seat, comprise sliding sleeve shell 7, be provided with sliding part 1 and resilient sleeve ball seat 4 in the sliding sleeve shell 7, be connected by shear pin 9 between sliding part 1 and the shell 7, be arranged at the top of resilient sleeve ball seat 4 between described sliding part 1 and the resilient sleeve ball seat 4 by screw thread 3 connections and sliding part 1, the inner surface of described sliding sleeve shell 7 is provided with groove 8, groove 8 is arranged at the below of resilient sleeve ball seat 4, the structure of described resilient sleeve ball seat 4 is equipped with sealing ring referring to accompanying drawing 3 between above-mentioned sliding part 1 and the sliding sleeve shell 7 and between resilient sleeve ball seat 4 and the sliding sleeve shell 7.Above-mentioned screw thread 3 is trapezoidal thread.
With reference to Fig. 1, Fig. 2, during use, a plurality of the linking together of the utility model fracturing sliding bush formed a system, at first pressure break ball 10 is dropped in the resilient sleeve ball seat 4, then increase the pressure in the tubing string, until after shear pin 9 cut off, sliding part 1 and resilient sleeve ball seat 4 moved downward together, open the pressure break mouth and finish pressure break.When resilient sleeve ball seat 4 moves to groove 8, the chuck of resilient sleeve ball seat 4 bottoms partly separately enters groove 8 by the elastic force of resilient sleeve, give pressure break ball 10 reserved enough spaces guarantee pressure break ball 10 smoothly by resilient sleeve ball seat 4 on the resilient sleeve ball seat 4 that falls in the next sliding sleeve.So such action just can be finished a series of pressure break work.
