摘要:
泰国E区块地层上部井段存在大段泥页岩,易造浆和发生垮塌;目的层属火成岩裂缝型油气藏,施工安全密度窗口窄,易发生喷漏同层复杂。针对该情况,开展了硫酸钾胺基钻井液配方室内研究,结果表明,硫酸钾和有机胺TJX-1配伍后抑制性明显提高,页岩膨胀率降低72.1%,滚动回收率达到92.9%;优化配方后的钻井液体系流变性能稳定,加入成膜封堵剂LXJ-1能够显著提高钻井液封堵性能。结合现场施工难点制定了配套技术方案,并在WBEXT-3D等多口井进行了成功应用,有效解决了松软泥页岩地层造浆和井壁垮塌问题,较有效地控制了目的层喷漏同层复杂,使同区块井机械钻速提高43.5%。
Abstract:
There are large sections of mud shale in the upper well section of Block E in Thailand,which makes it easy to make pulp and collapse. The target reservoir is an igneous fracture type oil and gas reservoir. The window of construction safety density is narrow,and the leakage can easy to occur in the same layer. Because of this situation,the K2SO4 amine-based drilling fluid formula was researched in the lab,the results showed that the combination of K2SO4 and organic amine TJX-1 obviously improved the inhibition,the expansion rate of shale was decreased by 72.1%,and the rolling recovery rate reached 92.9%. The rheological properties of the optimized drilling fluid system were stable,and the addition of film-forming blocking agent LXJ-1 can significantly improve the plugging performance of the drilling fluid. Based on the difficulties with the construction in the field,a supporting technical scheme was formulated and successfully applied to several wells,such as WBEXT-3D. The problems of slurry formation and shaft wall collapse of soft mud shale are effectively solved,the complexity of target formation leakage is effectively controlled,and the rate of penetration(ROP) of the well in the same block is increased by 43.5%.
