Abstract
The utility model discloses a scraping sand rammer which comprises a scraping sand rammer main body and a central tube. Four inclined sand scouring holes communicated with a central hole of the main body are arranged on the inclined shoulder part of the main body; four spiral sand-proof clamping slots are arranged on the surface of the main body; the central tube is threaded in the central hole of the main body; the lower end of the central tube is screwed with the main body through a threaded connector; and the part of the central tube, located at the lower part of the main body, is provided with an inclined sand scouring tine. Sand scouring fluid is pumped in from the ground and then is injected to the main body through an oil pipe; part of the sand scouring fluid obtains great scouring force through the central tube and the inclined sand scouring tine to scour a sand bridge at the bottom of an artificial well; and the other part of the sand scouring fluid returns from the annular rooms in the main body and the central tube to the annular room of the oil pipe through the inclined sand scouring holes so as to improve the sand carrying capacity. The scraping sand rammer overcomes the disadvantage of poor sand carrying capacity of the straight sand scouring mode.
Description
Technical field
The utility model relates to a kind of underground work instrument, particularly a kind of scraping sand washing machine.
Background technology
At present in the related underground work maintainability job execution process of oil exploitation industry, sand washing and scraping drifting flow chart are that substep carries out, in the job execution design, require each flow chart that relevant quality and safety requirements are arranged, not only ensure the quality of products but also down-hole accident can not take place, so can not in a kind of operation, carry out this two kinds of job executions simultaneously.
Summary of the invention
The purpose of this utility model is the problem that sand washing and scraping can not be carried out simultaneously when solving above-mentioned underground work, and a kind of scraping sand washing machine that can carry out drifting, scraping under the prerequisite that satisfies sand washing work is provided.
The utility model includes scraping sand washing machine body, central tube, the oblique shoulder of scraping sand washing machine body offers four inclined to one side holes of sand washing, the inclined to one side hole of sand washing is communicated with the centre bore of scraping sand washing machine body, the external surface of scraping sand washing machine body offers four spiral sand control draw-in grooves, central tube is set in the centre bore of scraping sand washing machine body, apparatus threaded jointing in central tube lower end is screwed onto with scraping sand washing machine body, and the part that central tube is positioned at scraping sand washing machine body bottom is a tiltedly point of sand washing.
The effect of four spiral sand control draw-in grooves in the utility model is to prevent that the sandinteeter that termination of pumping produced in the sand washing process from sinking to blocking scraping sand washing machine body, the effect in four inclined to one side holes of sand washing is to break up sand bridge on the scraping sand washing machine body with sand cleaning fluid, the sand washing tiltedly effect of point is the powerful kick that guarantees sand cleaning fluid, breaks up sand plug.
The course of work of the present utility model and principle are: ground pumps into sand cleaning fluid and is injected in the scraping sand washing machine body by oil pipe, part sand cleaning fluid reaches powerful sand washing power through central tube, the oblique point of sand washing, sand bridge in the sand washing artificial bottom of a well, the annular space of another part sand cleaning fluid in scraping sand washing machine body and central tube returns out from the inclined to one side hole of sand washing and enters the oil pipe annular space, to improve the prop-carrying capacity of sand cleaning fluid, improved the weak shortcoming of prop-carrying capacity in the positive sand washing mode.The sand control draw-in groove is a spirality, to guarantee the cylindricity of scraping sand washing machine body, reaches the requirement of scraping construction.
The beneficial effects of the utility model are:
1, better carries out the underground work construction, alleviate the job execution workload, reduce operation and account for the well time, improve rate when recovering the oil.
2, in a job execution operation, can finish sand washing and two kinds of underground work constructions of scraping simultaneously, have higher economic value by this instrument is installed.
Description of drawings
Fig. 1 is a half sectional view of the present utility model.
The specific embodiment
See also shown in Figure 1, be embodiment of the present utility model, it includes scraping sand washing machine body 1, central tube 3, the oblique shoulder of scraping sand washing machine body 1 offers four inclined to one side holes 2 of sand washing, the inclined to one side hole 2 of sand washing is communicated with the centre bore 7 of scraping sand washing machine body 1, the external surface of scraping sand washing machine body 1 offers four spiral sand control draw-in grooves 4, central tube 3 is set in the centre bore 7 of scraping sand washing machine body 1, the threaded jointing 5 of apparatus is screwed onto central tube 3 with scraping sand washing machine body 1, the part that central tube 3 is positioned at scraping sand washing machine body 1 bottom is a tiltedly point 6 of sand washing.
The effect of four sand control draw-in grooves 4 in the utility model is to prevent that the sandinteeter that termination of pumping produced in the sand washing process from sinking to blocking scraping sand washing machine body 1, the effect in four inclined to one side holes 2 of sand washing is to break up sand bridge on the scraping sand washing machine body 1 with sand cleaning fluid, the sand washing tiltedly effect of point 6 is the powerful kicks that guarantee sand cleaning fluid, breaks up sand plug.
Ground pumps into sand cleaning fluid and is injected in the scraping sand washing machine body 1 by oil pipe, part sand cleaning fluid reaches powerful sand washing power through central tube 3, the oblique point 6 of sand washing, sand bridge in the sand washing artificial bottom of a well, the annular space of another part sand cleaning fluid in scraping sand washing machine body 1 and central tube 3 returns out from the inclined to one side hole 2 of sand washing and enters the oil pipe annular space, to improve the prop-carrying capacity of sand cleaning fluid.
