1) PRD drill-in fluid
PRD钻开液
1.
A dynamic method is used to study PRD drill-in fluid and the formation time of filter cake on the core and flushing resistance of the filter cake to completion fluids.
室内采用动态方法研究了PRD钻开液与在岩心端面上的滤饼形成时间及该滤饼耐各完井工作液的冲刷性;采用浊度方法研究了PRD钻开液与完井作业液的配伍性。
2) PRD polymer drilling-in fluid
PRD聚合物钻井液
1.
When a well drilling job is completed,the residual gelled PRD polymer drilling-in fluid in the bottom must be treated by a proper gel breaker(GB) to prevent from reservoir formation damage.
用PRD聚合物钻井液钻井完钻后,须对井筒内余留的钻井液实施破胶处理,以免钻井液污染地层。
3) spud drilling fluid
开钻钻井液
4) drilling fluid
钻开液
1.
In the completion of horizontal wells, previous drilling fluid should be matched with consequent demulsification technique, in consideration of safety factors, solid-free drilling fluid system must be improved.
在水平井钻完井作业中,要求先前的钻开液能与后续的破胶技术相匹配,考虑到现场的安全因素,有必要对现有的无固相钻开液体系进行改进。
2.
HRD weak gel drilling fluid is a novel horizontal-well drilling fluid without clay.
HRD弱凝胶钻开液是一种新型无粘土相水平井钻开液,它所形成的弱凝胶具有独特的流变性,表观粘度低、动塑比高、低剪粘度高、静切力恢复迅速、无时间依赖性,具有很好的动态携砂和静态悬砂能力,能有效地克服水平井或大斜度井段携砂难、易形成岩屑床等问题。
