热德拜油田水平井优快钻井配套技术

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％。

Matching Technology of High Quality and High Speed Drilling for Horizontal Well in Redebye Oilfield

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.
