PRD弱凝胶钻井液性能评价

PRD弱凝胶钻井液是一套具有优异携沙性能,良好的滤失性能,对地层伤害较小的优良无固相钻井液。文中通过PF-VIS配制的一种PRD弱凝胶钻井液与普通的钻井液,在动滤失,岩心污染程度,以及PRD弱凝胶钻井液自身抗温性能三方面做的相关室内实验进行了对比。通过实验对比数据,对该钻井液的性能进行了评价,并证明其具有良好的抗温性能和储层保护性能。

The PRD weak gel drilling fluid performance evaluation

The PRD weak gel drilling fluid is a excellent portability sand performance,good fluid loss Performance and less damage to the stratum excellent free drilling fluid.Through in this article PF-VIS preparation of a PRD weak gel drilling fluid with ordinary drilling fluid.In the dynamic filtration,core pollution levels,and PRD weak gel drilling fluid temperature resistance three aspects of the laboratory experiments were compared.By experimental comparative data,to evaluate the performance of the drilling fluid and prove that it has good temperature resistance and reservoir protection performance.
