四川石油管理局川中矿区磨105井于1991年3月30日按设计要求顺利完钻,斜深3015m、垂深2721m,最大井斜角39°,最大水平位移1025m,整个钻井工程质量优。该井是一口工艺复杂,难度较大,困难较多的定向斜井兼钻井工艺试验井,它对钻井液提出了3个技术难题。一是良好的稳定井壁性能,二是良好的携砂和净化井底作用,三是较高的润滑性。为了解决这3个问题,川 The Well 105 of Sichuan Oilfield in Sichuan Basin was smoothly drilled according to the design requirements on March 30, 1991. The depth of dip is 3015m, the depth is 2721m, the maximum inclination is 39 ° and the maximum horizontal displacement is 1025m. The whole drilling project is of good quality. The well is a well-designed and difficult-to-process directional well drilling well test well, which poses three technical problems for drilling fluid. First, good stability of the borehole performance, the second is to carry a good sand and purify the bottom of the role, the third is a high lubricity. In order to solve these three problems, Chuan
