八面河油田保护油气层的钻井液技术分析

On the Drilling Fluid with the Reservoir Protecting Ability in Bamianhe Oil Field

随着石油勘探开发的不断深入,人们越来越意识到油气层保护的重要性。实施良好的储层保护技术措施,是提高勘探开发效益的有效方法。八面河油田经过二十年的勘探和开发,为确保油田的可持续发展,提高油田开发的综合经济效益,油气层保护技术至关重要。目前八面河油田地层面临油气层压力低、水敏性强、均质性差、结构疏松、易垮塌等特点,如何进行油气层保护,已经逐步成为钻井液技术研究的首要任务。

With the going on of oil exploration and drilling,people have come round to the importance of protecting the hydrocarbon reservoirs.A good protection technique can effectively improve the efficiency of exploration.After two decades of exploration,it’s imperative for Bamianhe Oil Field to employ reservoir protection technique to guarantee a stable development and better economic benefits.The stratum of Bamianhe Oil Field is plagued by low pressure,strong water sensitivity,poor homogeneity,loose structure and unstableness so how to protect reservoirs when drilling has become the priority of drilling fluid study.
