摘　　要：张店油田为屋脊状层状油藏、纯含油带窄,油层紧贴断层分布,若采用直井开采效果差,无法钻穿钻全所有含油层,利用双靶定向井钻井技术能够较快查明断层遮挡形成的多油层窄油藏,有效地完善注采井网,提高储量动用程度,使张店油田难采储量转化为可动用储量,变低效开发为高效开发。Zhangdian Oilfield is a layered reservoir where oil ~ bearing zones are narrow and located near faults. If developed with vertical wells, development effects would be poor as vertical wells cannot penetrate all oil layers. Dual - target directional wells can penetrate several narrow oil layers, effectively improve injection- production pattern, and put more oil reserves into production. Application of this technology in Zhangdian oilfield has converted the hard - to - recover reserves into producing reserves and the low efficiency wells into highly efficient wells.
