摘　　要：克拉玛依油田九区稠油油藏纵向上发育多套油层,主力油层齐古组注蒸汽吞吐、汽驱开发25年之后,已进入产量递减期。为了确保九区持续稳产,利用定向井技术结合直井,再建了一套开发克拉玛依组油藏的新井网,成功解决了地面井位难以确定的问题。定向井与直井的结合应用,保证了老区潜力层设计井网的实施和开发井网的完整性,实现了同时开发齐古组和克拉玛依组两套油层的目标。The heavy oil reservoir in District No.9 in Karamay oilfield is characterized by multi-set oil reservoirs in vertical,of which the major reservoir Qigu formation has developed by steam stimulation and steam drive processes for 25 years,and now it has entered into production decline stage.In order to keep the stable production of the District No.9,using directional well technology combined with vertical wells,a set of new well patterns for development of Karamay reservoir has established and successfully solved this problem.The combination and application of directional well and vertical well ensure the implementation of the potential layer design pattern and the integrity of the development pattern in this district,realizing the target of simultaneous development of Qigu reservoir and Karamay reservoir.
