Study on Treatment Technology of Coal Slurry Drilling

For coal slurry drilling method drilling technology is very important,but the use of waste drilling mud will cause serious environment pollution,how to solve the problem has become a waste mud treatment method of drilling wells cut a restrictive factors of the development. Experimental research group of different pH value,different metal cation in mud sedimentation rate and inorganic salt water and mud structure and the influence of the potential influence of Zeta dynamic studies,cationic discuss the influence of the change of mud. Experimental results show that the pH adjustment for mud will join the quality to the slurry after 6.8 dried mud weight of 4%～2.5% Fe3+ salt of the mud dehydration effect is good,and the engineering application.
