Research And Application On Complex Formation Blocks Cluster Directional Well Drilling Technology In Thailand Oil Field

Along with the development of drilling technology. Platform cluster well type oil industry at home and abroad have become a relatively mature drilling technology and is widely used in inland and offshore oilfield development. In view of the Thailand SINO-US formation soft hard interaction in oil fields. Had come on Tibetan development area. Convenient management of oil gathering and transferring.The NONG SA, BUNG MUANG block of the Thailand SINO-US oil land, is China’s overseas oil project for a long time, the region is all platform cluster Wells, has the following construction difficulties:complex formation; poor drill ability; the complex relationship of pressure; the narrow mud density window; the touch problems prominent; the late trajectory control is difficult.This article through to SINO-US oil platform cluster Wells of the research and application of the technology for directional well, For trajectory control soft hard interaction formation is difficult. Construction in complex geological conditions and Slow rate of penetration and so on, In the well ore trajectory control, reduce down hole complex situation and platform cluster Wells security technology has achieved a breakthrough, has obtained the good effect of scientific research and technology practice and economic and social benefits.In this paper, the research content to summarize cluster Wells technology experience, just to in the application of the technology, the forming technology of template, as a relatively mature drilling technology in petroleum drilling industry.The topic of research, implement the platform cluster well type in the successful application of SINO-US oilfield. Formed a set of cluster Wells well track precision control technology, drilling cycle is shorten by more than ten percent, Thailand every year profit margins in the construction well maintained at more than sixty percent.In this paper, the research process and the whole SINO-US directional well by analogy analysis, has completed the construction of the project 65 Wells now. provides resources for other projects. The technology is bound to other projects in the region scale popularization and application.
