Description
Technical field
The present invention relates to drilling liquid technology field, particularly to a kind of high inhibition Aethoxy Sklerol drilling fluid, for water sensitivity mud
The drillng operation of shale formation.
Background technology
Water sensitivity mud shale easily hydration swelling and cause undergauge, collapse, the down-hole such as bit balling and bit freezing complicated, give and bore
Well engineering brings harm greatly.Come with the oil base drilling fluid with high inhibition shale hydration dispersibility the most both at home and abroad
Solve problems.But oil base drilling fluid has, and cost is high, pollute the problem such as environment, poor stability.To this end, have oil base drilling well
Fluidity energy, and cost is relatively low, can meet the water base drilling fluid system of environmental requirement becomes the focus of research, such as polymeric alcohol at present
Drilling fluid, cation sulphonated polymer mud, but the inhibition such as polyglycol drilling fluid, cation sulphonated polymer mud is not enough, and lubricity is also
Cannot fully meet construction demand, cause when water sensitivity mud shale stratum carries out Horizontal Well Drilling well operations, the borehole wall peels off, collapses
Collapse, the down-hole complexity such as backing pressure occurs often.In recent years, investigated the polyamine type with strong rejection capability that a class is novel both at home and abroad
Water base drilling fluid system, this drilling fluid use polyamine and potassium ion with the use of, there is extremely strong suppression shale hydration swollen
Swollen ability, the high inhibition hydration of potassium salt can make stratum hardening, causes mud stone to produce crack, and the generation in crack can aggravate again
The intrusion of solid, liquid phase in drilling fluid, can cause the periodicity of mud stone well section to collapse time serious, potassium salt can aggravate drilling tool corruption in addition
Erosion, the too strong meeting of inhibition makes drilling fluid rheology be difficult to control to, and dehydration increases.
Summary of the invention
The present invention is directed to a mud shale borehole well instability difficult problem in prior art, provide one quickly borehole wall stratum to be realized
High inhibition and effectively block and stop the high inhibition Aethoxy Sklerol drilling fluid of filtrate invaded formation.
The object of the present invention is achieved like this, a kind of high inhibition Aethoxy Sklerol drilling fluid, each including following weight proportion
