钻井液用降粘剂基浆的确定

Definition of basic mud used inevaluation viscosity reducer

讨论了确定降粘剂基浆的几条原则,提出以降动切力率来表示降粘效果的概念.用大量的测试结果总结出各类基浆的配方、操作程序及污染物质的加量,结合理论解释其合理性.用常见各种牌号的降粘剂验证所选用基浆的可行性.

:This article discusses some criteria used for electing basic mud and a concept of vis-cosity reducing effect by using a ferm of miving fangential force reducing ratio,sums up theingredients of every kind of basic mud,operating procedure and adding amount of contami-nant,and theoretically shows the rationality of it,and verifies the feacibitity of elected mudby using commonly used viscosity reducers.
