摘要:
为加快热德拜油田水平井钻井开发步伐,通过对岩石力学特性、岩石理化特性、井眼轨道、钻具组合、钻头选型等方面的研究,形成了以PDC钻头复合钻井技术、井眼轨迹控制技术、防漏堵漏钻井液技术、筛管顶部双级注水泥固井技术等为主的科学、合理的配套工艺技术,并应用于现场施工,加快了热德拜水平井开发步伐,节约了开发成本。2012年水平井平均钻井周期为42.96天,完井周期53.38天;2013年水平井平均钻井缩短至19.58天;完井周期37天,同比钻井周期缩短54.4%,完井周期缩短41.1%。
Abstract:
In order to speed up the development of horizontal well drilling in Redebye oilfield, by the study on rock me-chanical properties, rock physical and chemical properties, wellbore trajectory, BHA and bit selection, a science is formed of mainly by PDC bit combined drilling, well trajectory control, plugging drilling fluid and two-stage cementing at screen top technologies, and a rational matching processing technology is also developed.These are applied in the field construc-tion to speed up the horizontal well drilling in Redebye and save the development cost.In 2012, the average cycle of hori-zontal well drilling was 42.96 days and well completion period 53.38 days;in 2013, those were 19.58 days and 37 days, being shortened by 54.4%and 41.1%respectively.
