国内完井技术现状及研究方向建议

STATUS QUO AND RESEARCH DIRECTION OF WELL COMPLETION TECHNOLOGY IN CHINA

完井是油气井建井过程中的重要环节,直接关系到油气勘探开发的效果和经济效益。国外对完井技术十分重视,通过多年的发展,在完井方面形成了许多成熟配套的技术。国内在完井技术方面虽然取得了一些进步,但是与国外相比,还有很大差距,特别是在不同储层合适的完井方式选择、水平井完井、欠平衡井完井、小井眼完井、分支井完井、高含硫气田完井等,从而影响了油气井的产量及经济效益。文中介绍了国内外的完井技术现状,分析了国内与国外的差距,并探讨了以后完井技术的研究方向。

The well completion is the important key in the well construction process,it influences the exploration& development effect and economic benefits of the oil and gas well. Overseas very attach importance to completion technology,through development in many years,many mature technologies have formed. Compared with the overseas,China have big gap in completion technology, especially in the selection of appropriate completion methods, horizontal well completion, under-balance well completion, small hole well completion, high sulphur gas field completion etc, thus the output and the economic benefits of oil/gas well has been affected. This article introduces the state of the art and existent problems of completion,and discusses the research direction of completion technology in the future in China.
