抗高温水基钻井液研究现状

Research Progress of High Temperature Resistance Water-based Drilling Fluid

井下复杂的地层状况(如高温)决定了钻井的深度,水基钻井液是钻井液的一种,钻井液处理剂的优化对深井的开采意义尤其重大,处理剂耐高温的性质往往决定钻探是否成功。论述了水基钻井液中处理剂耐高温性的研究现状,对耐高温水基钻井液中试剂进行比较和评价,并指明了今后的研究方向。

The complex conditions of downhole decide the depth of the drilling.Water-based drilling fluid is an important kind of drilling fluid. Its treating agent is the key to the exploitation of deep well, and high temperature resistance of the treating agent is very important. In this paper, the current status and progress of high temperature resistance research of the treating agent were discussed, and some suggestions about the future research were put forward.
