水平井测井解释技术综述

Technology Review on the log interpretation of horizontal well

水平井的大规模钻井和应用是20世纪后期石油工业的一个亮点.水平井技术在新油田开发和老油田调整挖潜上成效显著,它可降低勘探开发成本、大幅度提高油气单井产能和采收率等.回顾了水平井及水平井测井解释发展历史,比较了垂直井和水平井测井及解释评价上的异同,分析了水平井测井环境以及测井解释所面临的问题,简述了一些水平井测井数据处理方法及综合解释中应注意的问题,最后根据我国目前的水平井测井解释现状分析了存在的问题,提出了今后发展的思路:以跟踪国外和创新发展国内水平井解释技术为目标,开展复杂条件下各种测井方法的正反演研究,研究各种环境影响因素的校正方法,注意多学科的交叉综合,结合垂直井测井解释经验和水平井测井的特点提高水平井测井解释水平.

The highlight in oil industry is the application of horizontal well technology during the later of twentieth century. The remarkable effects of horizontal well technology on the development of oil fields result from the reduction of the costs of exploration and development, and the evident improvement of producility or recovery ratio of oilgas in single well, et al. The evolved history of horizontal well technology is described, the different and the same in log interpretation are illustrated between the horizontal well and the vertical well, the well logging environments and the current problems analyzed in the log interpretation of horizontal well, and some aspects being paid attention to in processing and comprehensive interpretation of horizontal well logs presented simply. The existing problens in the terpretation of harizontal well logging are pointed out according to the current situation in our country, and some ideas are showed in the end, that are, based on the following of foreign methods and the innovating of domestic technologies in horizontal well log interpretation, the research of forward and inversion methods should be done to logs in complex environment, the means investigated to correct the effects of various of environments, the integrated applications of multi-discipline knowledge and interpretation experiences of vertical well reinforced tO improve log interpretation of horizontal well.
