川东地区占三分之二进尺的311mm井段，有砂桥、沉砂，常需划眼；大段泥页岩地层易井塌，尤其是地面地层倾角大时，井塌就更为严重。为此，进行了MMH正电胶钻井液的室内试验和现场应用。结果表明，以MMH为主体的正电胶钻井液具有十分明显的“固／液”转化的独特的流变特性，结构能很快形成，又能很快且很容易地被拆散；水眼粘度η∞很低，卡森动切力τc和剪切稀释系数Im很高，剪切稀释性很好；有很好的井眼净化能力，有很好的抑制性和井壁稳定能力。所以，MMH正电胶钻井液在川东地区有广阔的推广应用前景。
The 311mm well section in east Sichuan, which is two-thirds of the footage, has sand bridges and grit. It is often necessary to draw an eye. Large shale formations are prone to collapses, especially when the dip of the ground strata is large. . To this end, the MMH positive gel drilling fluid laboratory tests and field applications. The results show that the MMH-based positive-electrode glue drilling fluid has a very distinct “solid / liquid” conversion of the unique rheological properties, the structure can be quickly formed, but also quickly and easily be disassembled; water-eye viscosity η ∞ low, Carson dynamic shear force τc and shear dilution coefficient Im is very high, shear thinning well; good wellbore purification ability, have good inhibition and borehole stability. Therefore, MMH positive rubber drilling fluid in the eastern region has a broad promotion prospects.
