| 摘 要： | 鄂尔多斯盆地部分油田区块发育相互重叠的多套层系,单井开发多套层系,可以有效提高单井产量,降低钻井成本。针对长庆油田目前一套井网多层开发特点,通过不同井身剖面、不同层间跨距等条件与注采井网适应性进行对比分析,优选出"直-增-稳-微降-小角度稳斜"五段式井身剖面及优化设计"五段式"井身剖面的造斜点、造斜率,通过两个试验区43口井钻井实践,初步实现一套井网两层双中靶钻井技术。

| Abstract: | There are overlapping sets of formations in the oil field on Ordos Basin.To increase the well production and reduce drilling cost,two formations are developed in one well.A well network multi-formation system of Changqing oilfield currently is discussed,by adaptability analysis of the span between the different formations,well profile and well network,optimized a "build-up-hold-drop down-small-angle hold" five-phase well profiles and kick off point and build-up rate.the well profile.Forty-three wells are drilled on two test districts,to achieve the desired results that two formations double-target hitting in one network |

| Keywords: | a set of well network doule-target hitting well profile optimized build-up rate |
