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.
