In order to speed up the development of horizontal well drilling in Redebye oilfield, by the study on rock mechanical 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 construction to speed up the horizontal well drilling in Redebye and save the development cost. In 2012, the average cycle of horizontal 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.
