Description
Technical field
The utility model relates to oil field, specifically refers to recovered oil inside pipe wall Shave tool.
Background technology
Along with the development of petroleum industry, rolling up of various oil field note sink hole, make various oil pipelines, aqueduct demand also increases, profit pipe tube inner wall after permanent use will be attached with many oil stains, the impurity such as dirt, because the main component of the surface dirt layer of profit pipe is firmly thick calcium carbonate scale and sulfate scale, containing a small amount of fine and close hard Fe2O3, BaSO-4, S--rSO-4, just comparatively block when using profit pipe to carry out the dynamic monitoring work such as the test pressure measurement of oil well and oil-field flooding, affect monitored results, bring difficulty to water filling simultaneously, sometimes need again to change pipeline toward contact, inconvenience is brought to well maintenance, for avoiding the generation of down-hole accident, profit pipe need be extracted and cleaning, nowadays with the cleaning of the chemical method such as pickling, not only comparatively serious to those encrustations, namely dirty thing thickness large and hard time, the de-sludging DeGrain of profit pipe, and seriously polluted, electromagnetic induction heating is better to the cleaning performance of viscous crude, wax deposition profit pipe, but is not very desirable to the elimination effect of dirty thing, and the Technolgy of High Pressure Water jet Cleaning also also exists high pressure dynamic seal (packing) instability, cause outlet system wastage large, the problems such as the efficiency of pump is low, the normal discharge pressure of high-pressure pump is 70Mpa, but actual discharge pressure is only 40 ~ 50Mpa, discharge pressure is low, makes out water kinetic energy little, directly causes that cleaning quality is unstable, cleaning first-time qualification rate is low, the serious profit pipe of therefore fouling, scale by foulant and chemicals stifled real after cannot realize high pressure water cleaning.
Utility model content
The purpose of this utility model is to provide recovered oil inside pipe wall Shave tool, solve in the past cleaning oil pipe trouble, cost is high and clean halfway problem.
The purpose of this utility model is achieved through the following technical solutions:
Recovered oil inside pipe wall Shave tool, comprise inside offer the support cylindrical shell of water injection path and be fixed on the scrub-brush of described support cylindrical shell rear, described support cylindrical shell is arranged at intervals with multiple cutter group, described cutter group comprises spaced set of blades A and set of blades B, multiple set of blades A, the external diameter of set of blades B increases progressively to the direction of rear along first section of supporting cylindrical shell, and it is identical with the internal diameter size of oil pipe near the external diameter of the set of blades B supporting cylindrical shell rear, support cylindrical shell and be provided with the swing cavity caved inward, the radial hole for water spraying be communicated with water injection path is had on the top of described swing cavity, the top of radial hole for water spraying is fixed with can at the water hose swinging free activity in cavity, the movable end of described water hose protrudes from the upper end of swing cavity and is placed between set of blades A and set of blades B.For the state that the Chemical cleaning means such as prior art mesohigh water jet cleaning and pickling are not good to the cleaning effect of dirt in oil pipe, by the mode of cutting in conjunction with water-jet cleaning and physics, degree of depth cleaning is carried out to the hard calcium carbonate scale of densification numerous in oil pipe and sulfate scale, to ensure reusing of oil pipe, thoroughly solve in the past cleaning oil pipe trouble, cost is high and clean halfway problem, during utility model works, the front end supporting cylindrical shell is placed in oil pipe, ensure the edge of a knife of cutter group and the contact internal walls of oil pipe, motor and water pipe is connected at the tail end supporting cylindrical shell, while motor drives support barrel body rotation, support cylindrical shell is pushed ahead, High-Pressure Water is injected again in water pipe, cutter group High Rotation Speed starts to cut the dirty thing of tube inner wall, now cut by cutter group the dirty thing chip produced then to pile up between oil pipe and support cylindrical shell, the utility model offers the swing cavity internally caved on support cylinder body outer wall, water hose is fixed on and swings in cavity, the high-velocity flow flowed out by water injection path enters in water hose through after radial hole for water spraying, water hose self has certain suppleness, swiftly flowing current can drive the movable end of water hose to freely swing in swing cavity, and then the emission direction of high-velocity flow is constantly changed, namely constantly start to rinse single cutter group cut the dirty thing chip of generation, clean current simultaneously and form eddy flow with support barrel body rotation, and then the other end of dirty thing chip along oil pipe is discharged, be positioned at the scrub-brush supporting cylindrical shell rear then the residual dirty thing that tube inner wall adheres to thoroughly to be removed, and then reach the object of oil pipe cleaning,
Wherein, be directed to the internal cleaning of the serious recovery oil pipe of fouling, the cutter group supported on cylindrical shell is carried out targeted design by the utility model, cutter group comprises set of blades A and set of blades B, and the external diameter of multiple set of blades A and set of blades B increases progressively to the direction of rear along first section of supporting cylindrical shell, and then first the cutter group supported on cylinder body outer wall can the part larger to oil pipe inside dirt thing thickness be cut, remaining dirty thing part thoroughly is cleared up by second or N number of cutter group, employ the combination of multiple cutter group substantially, the work overburden of first cutter group and follow-up N number of cutter group is avoided to occur the phenomenon of idle running, substantially increase cutting cleaning efficiency, and because support cylindrical shell and cutter group entirety form a taper shape, the dirty thing chip cutting can directly be discharged in oil pipe with current fast, prevent from oil pipe and support between cylindrical shell occurring blocking.
