我们在小口径复杂地层钻进中遇到漏水地层时，常用水泥灌浆堵漏，并用氯化钙作快干剂。在扫灰心时，由于氯化钙的作用，使皂化油破乳，并形成油泥粘附在钻具上，甚至将双管钻具粘在一起失去单动性。钻机也不能开高速，且因通水不良，导致烧钻。我们曾在皂化油中加入水玻璃，虽能减轻破乳的程度，但不能完全避免。后来我们经过试验，发现吐温 We encountered in the small bore complex strata drilled leakage strata, commonly used cement grouting plugging, and use calcium chloride as a fast drying agent. In despair, due to the role of calcium chloride, the saponified oil demulsification, and the formation of sludge adhesion to the drilling tool, and even the double-tube drill stick together lost mobility. Drill also can not open high-speed, and due to poor water, leading to burning. We used to add sodium silicate saponification oil, although can reduce the degree of demulsification, but can not be completely avoided. Later we tested and found Twain
