由于水平井技术具有能在很大程度上提高油田的动用储量和采收率等优点,越来越被各油田单位所重视,但在水平井钻井施工过程中,如何提高钻井速度、缩短钻井周期一直是工程技术人员所困扰的难题。文章详细分析了水平井快速钻技术在伊拉克AHDEB油田AD 205H井的应用,通过对地层岩性和倾角分析,从科学控制井眼轨迹,合理调整钻井参数,优化钻具组合和钻井液配置等方面入手,使水平井快速钻井技术得到成功实践。
As horizontal well technology can greatly improve the utilization of oil reserves and recovery and other advantages, more and more attention by the oil field units, but the horizontal well drilling process, how to improve the drilling speed and shorten the drilling cycle It has always been a problem for engineers and technicians. In this paper, the application of horizontal well rapid drilling technology to AD 205H well in AHDEB oilfield in Iraq is analyzed in detail. Through the analysis of formation lithology and dip angle, from the aspects of scientific control of wellbore trajectory, reasonable adjustment of drilling parameters, optimization of drilling assembly and drilling fluid configuration Start with horizontal well rapid drilling technology has been successfully implemented.
