丘陵油田陵2西区三间房组油藏注水运动规律

The rules of movement of injection water in the west of Ling 2 block of Sanjianfang Group of Qiuling Oilfield

目的了解丘陵油田陵2西区三间房组油藏注水在平面上、纵向上的运动规律。方法在充分认识油藏静态地质特征的基础上,利用压力测试、油井产液剖面、注水井吸水剖面等测试结果,结合注水井和采油井生产数据的动态分析,认识各种地质及生产动态因素对注水效果的影响和控制作用。结果丘陵油田陵2西区三间房组注入水在平面上主要受沉积微相、砂体平面延伸方向及储层物性三方面因素的控制,纵向上受沉积韵律性及层间差异性的影响。结论提出平面上封堵、转注,纵向上封堵、补孔及调整注水压力与注水量等措施,以达到提高油藏采收率的目的。

Aim To study the movement law of injection water in the horizontal and on the vertical in the west of Ling 2 block of Sanjianfang Group of Qiuling Oifield.Methods Based on the sufficient study in static state of the reservoir,by the use of the results of the pressure test, the production profiles, the injection profiles and the data of production, study kinds of geology and production factors which affected and controlled the movement of injection water.Results The injection water was mainly affected by sedimentary microfacies, sandbodies distribution and reservoir property in the horizontal, and sedimentary rhythm, interayer difference vertically.Conclusion Series of adjustment measures were recommended for the enhancement of oil recovery factor.
