水平井在草古1潜山裂缝性稠油油藏开发中的应用

Application of horizontal well in developing Caogu 1 buried-hill fractured heavy oil reservoir

方法采用油藏地质研究、数值模拟研究和现场试验分析等技术，对胜利油区草古１潜山裂缝性稠油油藏利用水平井开发的可行性进行了研究。目的在分析水平井开发潜山油藏可行性的基础上，利用水平井开发潜山稠油油藏，提高开发效果。结果利用水平井开发草古 １潜山裂缝性稠油油藏的生产实践证明，水平井日产油能力一般为 ２０～３０ ｔ，而相邻直井一般为 ７～１０ ｔ，水平井产油量是其邻近直井相同生产时间产油量的 ２～３倍。结论水平井开发潜山裂缝性稠油油藏取得了较好的开发效果。

Method Applying reservoir geological study, numerical simulation and site experimental analysis, feasibility of horizontal well in developing Caogu 1 buried-hill fractured heavy oil reservoir is studied. Purpose To improve recovery of buried-hill reservoir with horizontal well based on feasibility research. Result The proven production indicates that daily oil production with horizontal well ranges between 20-30 tons, while those of adjacent wells are only between 7- 10 tons. Conclusion Satisfactory results can be achieved in developing buried-hill fractured heavy oil reservoir with horizontal wells.
