Abstract
The utility model discloses a rapid sand-washing device for oil/water well operation in oil field, which comprises a suspended shaft (1), a quick coupler assembly (2), sealing assemblies (3), an intermediate adapter (4), and a central tube (5). The central tube (5) is connected with the lower part of the suspended shaft (1). A group of sealing assemblies (3) is arranged at the juncture of the central tube (5) and the suspended shaft (1) to form a sealing pair. The suspended shaft (1) is connected with the central tube (5) by the intermediate adapter (4) in a way that a blind hole in the lower part of the suspended shaft (1) is communicated with an inner through hole of the central tube (5). A radial through hole is formed in the blind hole section in the lower part of the suspended shaft (1) and used for the connection with the quick coupler assembly (2). The utility model has the advantages of simple structure, quick connection, no risk of sand plugging, and no environmental pollution.
Description
1. technical field:
The utility model relates to a kind of quick sand flushing device, is applicable to oil field oil, well operation, particularly is the power tool that a kind of sand washing is used.
2. background technology:
The oil field is in oil, well sand washing operation, and elbow sand washing commonly used though the method is simple, runs into the fireballing well of sand setting, easily causes sand card tubing string, and wastes time and energy, and easily misses contaminated environment.
3. summary of the invention:
The purpose of this utility model is: a kind of quick sand flushing device is provided, effectively prevents sand card tubing string, and time saving and energy saving, good seal performance, free from environmental pollution.
The utility model is achieved in that quick sand flushing device is made up of hanging axis, snap joint assembly, black box, transition joint, central tube, the bottom of hanging axis is connected to central tube, the cooperation place of hanging axis and central tube has one group of black box to constitute sealing pair, hanging axis is connected by transition joint with central tube, the blind hole of hanging axis bottom and the inner via hole of central tube join, and the blind hole section in the hanging axis bottom has a radial direction through hole and is connected with the snap joint assembly; During construction, the upper end card elevator of hanging axis, hose is connected on the snap joint assembly, the following termination sand clean out pipe post of central tube, water under high pressure is from hose during sand washing, the snap joint assembly enters inner chamber and implements sand washing to tubing string, when having dashed an oil pipe, take elevator, hose is thrown off fast with the snap joint assembly, hydraulic tongs unloads this device from the upper end of well head sand washing tubing string rapidly, meanwhile, the sling sand washing oil pipe of the another set of quick sand flushing device that another root connects already of elevator, hydraulic tongs sand washing tubing string rapid and in the well is connected, snap joint assembly and hose rapid abutting joint are continued sand washing to sand flushing device, circulate repeatedly thus and finish until sand washing.
The utlity model has simple in structurely, connection speed is fast, and is easy to operate, prevents tubing string sand card, characteristics such as free from environmental pollution.
4. description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Among Fig. 1, the 1-hanging axis; 2-snap joint assembly; The 3-black box; The 4-transition joint; The 5-central tube
5. embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further elaborated:
The utility model is by hanging axis (1), snap joint assembly (2), black box
(3), transition joint (4), central tube (5) are formed, the bottom of hanging axis (1) is connected to central tube (5), hanging axis (1) has one group of black box (3) to constitute sealing pair with the cooperation place of central tube (5), hanging axis (1) is connected by transition joint (4) with central tube (5), the blind hole of hanging axis (1) bottom and the inner via hole of central tube (5) join, and the blind hole section in hanging axis (1) bottom has a radial direction through hole and is connected with snap joint assembly (2); During construction, the upper end card elevator of hanging axis (1), hose is connecing on the snap joint assembly (2), the following termination sand clean out pipe post of central tube (5), water under high pressure is from hose during sand washing, snap joint assembly (2) enters inner chamber and implements sand washing to tubing string, when having dashed an oil pipe, take elevator, hose is thrown off fast by snap joint assembly (2), hydraulic tongs unloads this device from the upper end of well head sand washing tubing string rapidly, meanwhile, the sling sand washing oil pipe of the another set of quick sand flushing device that another root connected already of elevator, hydraulic tongs sand washing tubing string rapid and in the well is connected, snap joint assembly (2) and hose rapid abutting joint are continued sand washing to sand flushing device, circulate repeatedly thus and finish until sand washing.
