The oilfield crude oil pipeline paraffin removal tool of claim 1, wherein: the center shaft hole of blade holder is provided with the location tangent plane, and the shaft hole terminal surface is the D type, and cooperatees with the location tangent plane of output shaft, is difficult to skid to be convenient for fix with screw.

The technical field is as follows:

the invention relates to an oil field pipeline cleaning technology, in particular to a paraffin removal cutter for an oil field crude oil pipeline.

Background art:

in the process of oil exploitation, crude oil needs to be pumped to the ground from the underground, because the temperature of the oil in the underground deep layer is higher, wax contained in the crude oil is liquid and has good fluidity, the temperature of the crude oil is lower as the crude oil is closer to the ground, the wax is separated out from the crude oil and is attached to the inner wall of the oil pumping pipe, the wax attached to the inner wall of the oil pumping pipe is thicker and thicker for a long time, the inner diameter of the oil pumping pipe is smaller and smaller, and even the oil pumping efficiency is seriously influenced due to blockage. At present, tools and pipe columns in a well are placed on the ground, the pipe columns are cleaned by a steam vehicle and then are put into the well, or the well is washed at high temperature and high pressure, or the pipe columns are cleaned in a hoisting and pulling mode, but the production period is greatly prolonged by the modes, and the production cost is increased.

The invention content is as follows:

the technical problem to be solved by the invention is as follows: overcome prior art's not enough, provide a reasonable in design, can progressively clear up and clean effectual oil field crude oil pipeline paraffin removal cutter.

The technical scheme of the invention is as follows:

the utility model provides an oil field crude oil pipeline paraffin removal cutter, includes blade holder and blade, the blade holder is cylindrical, and its one end is provided with central shaft hole, and the other end has two at least fixed slots along the circumference equipartition, each all fix one in the fixed slot the blade, the pore wall that runs through central shaft hole is provided with the screw hole, be provided with the screw in the screw hole, each the blade all includes the cutter body, the interval is provided with the sword tooth on the cutter body, all the tooth root line of sword tooth is the broken line to, each broken line for the contained angle of blade holder center pin is different, makes the blade presents the shape that the front end is little the rear end is big, is convenient for cut the pipeline.

The central shaft hole is sleeved on an output shaft of a rotating motor of the power crawling device and is fixedly connected with the output shaft through the screw, or the central shaft hole is sleeved on one end of the transition shaft and is fixedly connected with the other end of the transition shaft through the screw, and the other end of the transition shaft is fixedly connected with the output shaft of the rotating motor.

The center shaft hole of blade holder is provided with the location tangent plane, and the shaft hole terminal surface is the D type, and cooperatees with the location tangent plane of output shaft, is difficult to skid to be convenient for fix with screw.

The invention has the beneficial effects that:

1. the invention removes the adhered objects on the inner wall of the crude oil pipeline by rotary cutting of the cutter, and particularly removes the paraffin on the inner wall of the crude oil pipeline, thereby having better effect.

2. The outer surfaces of the blades are provided with the serrated cutter teeth, so that the cutting effect is improved, the generatrix of the outer surfaces of the blades is in the shape of a broken line cone, the blades can be cleaned gradually, the cutting difficulty is reduced, the cutting efficiency is improved, and in addition, the cutter seat is flexible and can swing, so that the cutting range is enlarged.

3. The shaft hole of the tool apron is provided with the positioning tangent plane, the end surface of the shaft hole is D-shaped and is matched with the positioning tangent plane of the output shaft, so that the tool apron is not easy to slip and is convenient for jackscrew fixation.

4. The cleaning device has the advantages of reasonable design, capability of gradually cleaning, good cleaning effect, strong practicability and higher economic and social benefits.
