Described well drilling pipe column lower end is connected with drill bit.Drilling fluid containing solid phase abrasive particle is ejected by the hydrophthalmia of well drilling pipe column from drill bit, reach shaft bottom and up return, on the drilling fluid that returns quickly through the annular clearance of well drilling pipe column and the borehole wall, make drilling fluid form a kind of abrasive Flow with certain erosion ability, erosion grinding sticks to landwaste and the mud cake of the borehole wall.Therefore the abrasive Flow that the drilling fluid containing solid phase abrasive particle is formed can expand borehole diameter, solves and adheres to bit freezing and hole shrinkage bit freezing problem.This abrasive Flow erosion grinding can also be stuck in junk (as block is fallen in rock stratum) between the borehole wall and well drilling pipe column simultaneously, abrasive Flow has stronger ablation, can by little for the size of junk mill, by rotating and shortly carrying well drilling pipe column, make junk loosen and be taken out of well head by abrasive Flow, reach solution and fall block bit freezing problem.
Described drilling fluid cleaning system comprises solid control equipment and sewage-treatment plant, and solid control equipment and the annular clearance between well drilling pipe column and the borehole wall are connected, and sewage-treatment plant is connected with solid control equipment.By in drilling fluid that annular clearance returns out containing a large amount of landwaste, abrasive particle and other solid-phase component, use solid control equipment that solid matter is isolated drilling fluid, re-use sewage-treatment plant and drilling fluid is made purified treatment, reach the requirement of environmental protection.
Described sewage-treatment plant is connected with drilling fluid pot, and the drilling fluid after sewage-treatment plant purified treatment can inject drilling fluid pot, recycles.
Described sewage-treatment plant is connected with dosing pond, and the drilling fluid after sewage-treatment plant purified treatment can inject dosing pond, recycles.
Described sewage-treatment plant is connected with nature, and the drilling fluid after sewage-treatment plant purified treatment, reaches environmental protection requirement, directly can be discharged into occurring in nature.
In technique scheme, the high-pressure spray well system beneficial effect containing solid phase abrasive particle of the present invention is:
1. the abrasive Flow that the drilling fluid containing solid phase abrasive particle is formed, erosion grinding sticks to the landwaste of the borehole wall, plays and expands well and make the borehole wall smooth, improves the effect of hole quality, and solves the problem adhering to bit freezing, undergauge bit freezing simultaneously;
2. the abrasive Flow that the drilling fluid containing solid phase abrasive particle is formed, while expansion well, erosion grinding can also be stuck in junk (as block is fallen in rock stratum) between the borehole wall and well drilling pipe column, solve block bit freezing problem;
3. drilling fluid is through sewage-treatment plant, reaches the requirement of environmental protection, and the drilling fluid after purified treatment can recycle.
