Abstract
In the construction of oil field well repairing operation, a through scraping, flushing and grinding integrated tool. Is characterized in that: the lower part of the upper joint is in threaded connection with the ball seat short joint; the upper part of the ball seat short joint is provided with a ball seat, and the lower part of the ball seat short joint is in threaded connection with the whole straight groove body; the internal thread at the upper part of the scraping shell is connected with the external thread at the lower part of the straight groove body, the internal thread at the lower part is in threaded connection with the milling head of the spiral groove through mill, 2 rows of grooves are longitudinally arranged at the middle part, 3 grooves are transversely arranged respectively, a pressure spring and a cutting board are arranged in each groove, and each groove is fixed by a fixed stop block, a fixed block and an inner hexagon screw in sequence; longitudinal grooves are uniformly distributed on the outer side of the whole straight groove; spiral grooves are uniformly distributed on the outer side of the spiral groove through-grinding milling head, and wear-resistant materials are laid at the bottom of the spiral grooves. The effect is as follows: the construction method has the advantages that engineering quality accidents are avoided to the maximum extent, one-trip pipe column is started to complete drifting, scraping, sand washing, milling and pipe column pressure test construction, the problems of long well occupying period and high well repairing cost are solved, and construction efficiency is improved.
Description
Technical Field
The utility model discloses an in the construction of oil field workover operation, a logical scraping towards the examination integration instrument that grinds, mills, tubular column pressure testing carries out drifting, scraping, sand washing.
Background
In the process of oil field development, for a measure construction well, a drift size gauge is used for verifying the integrity of a sleeve, a scraper is used for treating dirt and burrs on the inner wall of the sleeve, and a normal construction process can be carried out only after the pressure test of a tubular column is qualified, wherein during construction, the accidents of drill sticking and tubular column blockage are caused due to small inner hole of a tool and small clearance between the tool and the sleeve and poor washing effect; when a large-diameter tool is put into a high-inclination well for sand washing construction, dirt scraped by a pipe column and the tool is deposited on the upper part of the tool, so that the pipe column is stuck and blocked; the inner wall of the sleeve is processed by milling a cone to form scales and salt, and the inner hole is small, the water tank is straight, so that the tool is easy to block, and the washing effect is poor; when drifting, scraping, sand washing, milling and tubular column pressure testing are carried out, no whole efficient tool exists, so that only single-process construction can be carried out when the tubular column is started and stopped, and the construction benefit, the construction period and the well repairing cost are seriously influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a, when workover operation measure well construction, can take one trip the tubular column just can accomplish drifting, scraping, sand washing, milling and tubular column pressure testing construction, solve the problem that exists above, have that the practicality is strong, safe and reliable is showing the advantage.
The utility model discloses a realize like this:
this lead to scraping towards examination integration instrument of grinding comprises top connection 1, ball seat short circuit 2, straight recess expert body 3, scraping casing 4, spiral recess lead to mill cutter head 5, ball seat 6, ball 7, cutting board 8, pressure spring 9, fixed dog 10, fixed block 11, soket head cap screw 12. The upper part of the upper joint 1 is in threaded connection with a well-descending pipe column, and the lower part of the upper joint is in threaded connection with the ball seat pup joint 2; the ball seat 6 is arranged at the upper part of the ball seat short joint 2, and the lower part of the ball seat short joint is in threaded connection with the straight groove whole body 3; the internal thread at the upper part of the scraping shell 4 is connected with the external thread at the lower part of the straight groove through body 3, the internal thread at the lower part is in threaded connection with the milling head 5 of the spiral groove through body, 2 rows of grooves are longitudinally arranged at the middle part, 3 grooves are transversely arranged respectively, a pressure spring 9 and a cutting board 8 are arranged in each groove, and are respectively and sequentially fixed by a fixed stop block 10, a fixed block 11 and an inner hexagon screw 12; longitudinal grooves are uniformly distributed on the outer side of the straight groove whole body 3; spiral grooves are uniformly distributed on the outer side of the spiral groove through-grinding milling head 5, and wear-resistant materials are paved on the convex parts at the bottom.
The utility model discloses following technical scheme has still been adopted:
the assembled ball seat 6 is positioned in the upper joint 1, and can be used for throwing a ball 7 according to construction requirements to carry out pressure test on the pipe column.
The utility model has the advantages that:
the construction method has the advantages that engineering and quality accidents are avoided to the maximum extent, one-trip pipe column is started to complete drifting, scraping, sand washing, milling and pipe column pressure test construction, the problems of long well occupying period and high well repairing cost are solved, and construction efficiency is improved.
Drawings
FIG. 1 is a schematic view of the structure of the scraping, punching, grinding and testing integrated tool of the present invention
Detailed Description
The invention will be further described with reference to fig. 1:
example (b):
during construction, a tool with a proper outer diameter is selected according to the size of the casing and construction requirements, the tool is connected to the bottom of a construction pipe column, and the construction pipe column is put into the casing according to the operation regulation requirements. By combining the straight groove whole body 3 and the spiral groove through-grinding milling head 5, on the premise of meeting the using requirement of the well dredging verification sleeve integrity, the annular space of the oil sleeve is increased, the drill clamping accident caused by dirt deposition is avoided to the maximum extent, and a foundation is laid for realizing the integration of through-scraping; through the organic combination of the straight groove whole body 3, the scraping shell 4 and the spiral groove general grinding milling head 5, the inner diameter of the tool is increased, the integration of well dredging and scraping is realized, and the accidents of drill jamming and pipe column blockage caused by dirt deposition are avoided to the maximum extent. Meanwhile, sand washing, milling and pipe column pressure test construction can be carried out according to construction requirements, and the milling effect is effectively improved through the spiral grooves and the wear-resistant materials.
