2013年9月19日,由川庆钻探长庆钻井总公司施工的长庆油田第1口水平段超过2 000 m的三维油井水平井——固平28-21井顺利完井,水平段长2 006 m,位垂比达1.73,创造长庆油田油井水平井多项新纪录。这口井位于陇东油田合水区域,是长庆油田为解决这个区域储层品质差、定向井开发单井产量低的难题,进一步落实油藏规模及油层发育状况,为下一步大
On September 19, 2013, the 3-D well horizontal well-Guping 28-21 with a depth of more than 2 000 m at the first section of the Changqing Oilfield constructed by Chuanqing Drilling Company Limited Changqing Drilling Company was successfully completed. The horizontal section length 2 006 m, the bit sag ratio of 1.73, creating a number of horizontal wells in Changqing Oilfield a number of new records. This well is located in the Hedong area of the Longdong oilfield and is a problem for the Changqing oilfield to solve the problems of poor reservoir quality in the region and low single well production in directional wells. The further implementation of reservoir size and reservoir development is the next step toward large
