The utility model discloses a cleaning device for mud cake on the inner wall of a drill rod. The cleaning device consists of a reciprocating pump, a high-pressure hose, a water joint, a winch, a fixed pulley and a high-pressure jet current cleaning tool, wherein the high-pressure jet current cleaning tool is connected with the high-pressure hose, and is conveyed to a position to be cleaned in the drill rod through the winch; the reciprocating pump is used for pumping a circulating medium, i.e., drilling mud into the high-pressure jet current cleaning tool through the high-pressure hose; a cleaning medium sprayed out of a spray nozzle on the side wall of the high-pressure jet current cleaning tool at a high speed can be used for fulfilling the aim of cleaning mud cake on the inner wall of the drill rod; and in the previous process, the reciprocating pump is used for providing required power for cleaning the inner wall of the drill rod, and the winch is used for driving the high-pressure jet current cleaning tool to ascend or descend in the drill rod through the high-pressure hose, so that cleaning of the inner wall of the entire drill rod is realized. Due to the adoption of a method disclosed by the utility model, the problem of incapability of placing a latch jack and lifting an inner pipe assembly out of a drill hole caused by scaling on the inner wall of the drill rod during rope core drilling can be solved effectively, and high cleaning efficiency and high cleanliness are realized.
Description
Technical field
The utility model relates to a kind of cleaning device of drilling rod inwall mud skin, and this device is used to clean the mud skin of wire line coring drilling rod inwall.
Background technology
As everyone knows, core drilling generally adopts the diamond wire line coring to creep into, and basket can be freely put in the drilling rod at the bottom of the hole, does not propose drilling rod when coring, and with special-purpose fisher inner tube assembly is salvaged, and completion is cored.The big efficient of coring that improved of this drilling method has alleviated working strength of workers.But the rod rotation speed that the diamond wire line coring creeps into is high, is generally 800～1100r/min, and solid phase particles in the mud is because bigger centrifugal force can be attached to forming the mud skin on the drilling rod inwall, and this phenomenon is called drilling rod encrustation effect.Analyzing the reason of wire line coring drilling rod encrustation, is solid matter in the mud, comprises clay particle, rock dust, not consoluet chemical treatments or flocculate, and the deposit of other solia particles on inside pipe wall.Solid phase particles in the mud is attached to tube wall on centrifugal action, and constantly deposition and compacting, the cementation of clay and organic polymer in addition, and deposit will dewater gradually and become very closely knit, and stick to securely on the drilling rod inwall.
The drilling rod inwall influences the input of fisher and the lifting of inner tube assembly after forming the mud skin, and inner tube assembly is stuck in drilling rod when often occurring coring; When throwing in inner tube assembly, transfer not in placely, cause drilling accident.In order to obtain rock core, the scene often need propose several to tens drilling rods, just can transfer fisher inner tube assembly is salvaged, and has increased non-cutting time, has influenced drilling efficiency.
The processing mode that generally adopts now is the solid concentration in the control mud.For reducing solid content (general requirements sand content＜0.2%) in the mud, the diamond wire line coring creeps into the lows solids mud that adopt more now.That have even adopt no solid phase mud.The job site also adopts vibrosieve, hydrocyclone to wait the solid concentration of controlling in the flushing liquor.But after running into nature and making the stratum of slurry, still have the mud skin to accumulate on the drilling rod inwall.Because it is high rotating speed grinding formula detritus that the diamond wire line coring creeps into the mechanism of fractured rock, in drilling process, inevitably landwaste can appear.Run into such stratum, will regularly detect the solid concentration in the mud.If find untimelyly, fisher still can occur and can't drop into inner tube assembly and can't be promoted to the problem outside the hole.Though clay-free drilling fluid is played a role to control mud content, the mud cost of raw material is too high, and certain limitation is arranged.After the drilling rod encrustation takes place in the job site; Usually drilling rod is proposed several, unloading lies on the workbench, with a thicker wire; On thicker wire, adopt on-the-spot woven bag or rag to break into joint; Be admitted to the drilling rod inwall from an end of drilling rod, pull out, realize cleaning the mud skin of drilling rod inwall from an other end.
Summary of the invention
The purpose of the utility model is in order to solve during wire line coring creeps into; Because drilling rod inwall mud skin is blocked up; Causing that fisher can't drop into inner tube assembly can't be promoted to the problem outside the hole; And woven bag or rag that the thicker wire that extensively adopts now fixedly breaks into joint clean the low and cleaning dirty problem of drilling rod inwall mud skin drilling efficiency, and the cleaning device of the drilling rod inwall mud skin that a kind of cleaning efficiency is high, wash degree is high is provided.
The utility model is made up of reciprocating pump, high-pressure hose, water swivel, winch, fixed pulley, high-pressure spray cleaning means; The high-pressure spray cleaning means is to be made up of reducing joint, outer tube and guide head; The upper end of outer tube is fixedly connected reducing joint; The lower end fixed guide head of outer tube, the sidewall of outer tube offer the interior low outer height of several spray-hole spray-holes and are oblique setting; Eight spray-holes are divided into two layers and arrange; Four every layer are evenly distributed, the layer with layer between corresponding spray-hole be 45 °, high-pressure hose one end links to each other with the outlet pipe of reciprocating pump; The other end of high-pressure hose is communicated with water swivel; The other end of water swivel is communicated with high-pressure rubber pipe, and high-pressure rubber pipe one end is wrapped on the winch, and high-pressure rubber pipe is connected with the high-pressure spray cleaning means through the top fixed pulley; Realize high-pressure rubber pipe and rising and the decline of high-pressure spray cleaning means in drilling rod through winch, high-pressure rubber pipe is communicated with the reducing joint of the high-pressure spray cleaning means of bottom.
The beneficial effect of the utility model: can effectively solve during wire line coring creeps into, because of the drilling rod encrustation can't drop into the problem that fisher and inner tube assembly can't propose to hole; Technology is simple, easy construction; Good through the test cleaning performance, can be widely used; In the drilling process, confirm the wash number of drilling rod inwall, can avoid the skinning problem of drilling rod inwall effectively according to strata condition; Cleaning efficiency is high and wash degree is high.
