摘要
大牛地属于低压、低渗、低丰度的三低油气藏,能否实行优快钻井成为制约水平井发展的主要因素,通过对井身结构、钻具组合、钻头选型及泥浆体系结构等统计分析,总结出适合大牛地气田水平井优快钻井技术,形成了一套大幅度提高机械效率、缩短钻井周期,适合大牛地工区的优快钻井技术。
Daniudi is an oil arid gas reservoir with low pressure, low permeability and low abundance, whether the opti- mized fast drilling is in put in use become the main factors restricting the development of horizontal wells. Through the sta- tistical analysis on the well stnJcture, BHA, bit selection and the drilling mud system, an optimized fast drilling technology is summarized, which is suitable for Daniudi gas field and can snbstantially improve the drilling speed and shorten the drill- ing cycle.
