红浅1 井区八道湾组油藏水平井开发优化研究

针对准噶尔盆地红浅1 井区八道湾组稠油油藏扩边及未动用储量的地质特点，运用数值模拟方法、经济分析方法，进行了水平井部署优化研究。在确定不同油价下水平井产量界限的基础上，优化水平井的关键技术参数，确定厚度下限为2 m，水平段长度200~300 m，水平井井距100 m.研究结果表明，运用水平井整体吞吐开发可以取得较好效果，采收率可达到28.4%.

Horizontal Well Deployment Optimization in Badaowan Formation in Wellblock Hongqian-1

In view of the geological characteristics of the delineation and undeveloped reserves in Badaowan heavy oil reservoir in Wellblock Hongqian-1 in Junggar basin, research on the integral steam-stimulation horizontal well deployment optimization is made by means of numerical simulation and economic analysis. According to the economic production limits under different oil prices, the technical parameters have been optimized for horizontal well deployment. It is determined that the low limit of pay zone thickness for horizontal well development is 2 m, the lateral length is 200 ～300 m, the well spacing is 100 m. The study shows that using integral steam-stimulation horizontal well development in this well block can get satisfactory results, and the recovery factor can be up to 28.4%.
