Abstract
A sand washer for scraping a sleeve of an oil water well comprises an upper connector, a main body, a spring, tile teeth and a lower connector and is characterized in that the main body is in a cylindrical shape and provided with a central hole, the upper end portion of the main body is provided with a male thread connected with an upper connector thread, the lower end portion of the main body is provided with a male thread connected with a lower connector thread, three V-shaped grooves are disposed at the periphery between the upper male thread and the lower male thread at the 120-degree position, and three concave grooves are positioned between the V-shaped grooves. Three tile teeth are embedded in the three concave grooves, the inner surfaces of the tile teeth are provided with grooves, and the outer surfaces of the tile teeth are provided with inclined grooves with downwards inclined groove openings. Springs are positioned in the grooves on the inner surfaces, the upper ends of the tile teeth are fixed with the upper connector, and the lower ends of the tile teeth are fixed with the lower connector, and the sand washer for scraping the sleeve of the oil water well is formed. The sand washer for scraping the sleeve of the oil water well has the advantages that the sleeve can be scraped and sand at the shaft bottom can be washed in one time of dismounting a tubular column of the sand washer for scraping the sleeve of the oil water well, thereby being reliable in working and saving cost of well maintenance.
Description
Technical field
The utility model involves in a kind of oil-water well operation downhole tool, and specifically a kind of oil-water well is scraped the cover sand washing machine.
Background technology
What be used for oil-water well at present scrapes the cover device; Do not design flow sand washing, sediment outflow passage, can only scrape the dirty sand on the casing wall, can not be used for the sand washing of oil-water well shaft bottom, strike-off and two operation procedures completion of shaft bottom sand washing need; Grow duty cycle, take to advance effort, improved operating cost.
Summary of the invention
The purpose of the utility model provides a kind of oil-water well and scrapes the cover sand washing machine, overcomes the deficiency that above-mentioned prior art exists:
The technical scheme of the utility model realizes in the following manner:
The utility model comprises top connection, main body, spring, watt tooth, lower contact, and it is cylindrical to it is characterized in that main body is made as, and is provided with centre bore; The upper end is provided with the male thread that is threaded with top connection, and the bottom is provided with the male thread that is threaded with lower contact, on 120 ° orientation of the periphery between the male thread up and down, is provided with three V-type grooves; Between the V-type groove, be provided with three Baltimore grooves, be inlaid with three watts of teeth in three Baltimore grooves, the inner surface of three watts of teeth is provided with groove; External surface is provided with the skewed slot of notch under oblique, is provided with spring in the inner surface recesses, and the upper end of watt tooth is fixed with top connection; The lower end of watt tooth is fixed with lower contact, constitutes oil-water well and scrapes the cover sand washing machine.
The beneficial effect of the utility model has been that oil-water well is scraped cover sand washing machine tubing string next time, can accomplish two work of scraping cover and shaft bottom sand washing, and reliable operation is practiced thrift workover cost.

The specific embodiment
For further disclosing technical scheme of the present invention, elaborate through embodiment below in conjunction with Figure of description: the utility model comprises top connection 1, main body 2, spring 3, watt tooth 4, lower contact 5, and it is cylindrical to it is characterized in that main body is made as; Be provided with centre bore, the upper end is provided with the male thread that is threaded with top connection, and the bottom is provided with the male thread that is threaded with lower contact; On 120 ° orientation of the periphery between the male thread up and down, be provided with three V-type grooves, between the V-type groove, be provided with three Baltimore grooves, be inlaid with three watts of teeth in three Baltimore grooves; The inner surface of three watts of teeth is provided with groove; External surface is provided with the skewed slot of notch under oblique, is provided with spring in the inner surface recesses, and the upper end of watt tooth is fixed with top connection; The lower end of watt tooth is fixed with lower contact, constitutes oil-water well and scrapes the cover sand washing machine.
The utility model operating principle and use method of operating are: the two cover oil-water wells that will assemble are scraped the cover sand washing machine; Top connection 1 screwed connection upper end oil pipe; Lower contact connects lower end oil pipe and sand washing mouth; Rely on shaft mouth operation equipment to be lowered in the Casing Failure, these spring 3 support watt teeth 4 of scraping in the cover sand washing machine are close to internal surface of sleeve pipe when scraping cover, and following drain line is wiped the foreign material that are bonded on the internal surface of sleeve pipe off.After scraping the cover end; Drain line is when sand washing mouth prospect pit bed load face slowly; Carry oil pipe suitably; And install well head and pipeline, and rely on ground installation to inject the high pressure liquid stream in the oil pipe again, scrape circular hole impact shaft bottom sand in main body 2 interior manhole to the sand washing in the center mouths in the cover sand washing machine through this; At this moment shaft bottom sand returns (drain line is slowly descended on sand washing limit, limit) under the carrying of high pressure liquid stream; Constantly discharge well head through lower end sand washing mouth outer wall, oil casing annular space to this main body 2 outside cylinder place three V-shaped groove sediment outflows passages and upper end oil casing annular space of scraping in the cover sand washing machine again, arrive the artificial bottom of a well until sand washing, thereby reach the purpose that oil-water well is scraped cover and shaft bottom sand washing.
