阶梯水平井双储层合采适用性研究
|
摘要
针对曹妃甸油田阶梯水平井(简称阶梯井)适用储层条件不明确的问题,从储层平面距离、纵向深度差2方面,开展阶梯井储层适用性分析。以地下渗流理论为基础,结合节点分析法,开展不同储层条件下阶梯井产出剖面分析。研究表明,当储层平面距离不大于200 m、纵向深度差不大于30 m时,阶梯井90%的水平段能够有效产出,适合联合储层开采。将研究成果应用于曹妃甸油田明化镇组,部署实施阶梯井1口,双储层联合开发增油效果明显。该研究为边际储量的动用开发提供了新思路。
In order to determine the applicability of the step horizontal well in Caofeidian Oilfield,the step horizontal well applicability for reservoir was analyzed from the lateral reservoir distance and longitudinal depth. The stepped horizontal well production profiles under different conditions were analyzed on the basis of the underground seepage theory and node analysis. Research indicates that 90% of the lateral section contributes to production when the lateral reservoir distance is nor more than 200 m and the longitudinal depth is nor more than 30 m,which is applicable for multi-interval mingled production. It was applied to Minghua Town Formation of Caofeidian Oilfield. A step horizontal well was deployed and implemented,which gains favorable production performance with dual-reservoir comingled production. This research could provide a new idea for the production of marginal reserve.
