严重层内非均质油藏提高水驱波及体积技术研究

Research of improving waterdrived swept volume technology in serious inner heterogeneous of layer reservoir

本文探讨严重层内非均质油藏改善开发效果的途径 ,应用油藏描述技术研究沉积微相、储层非均质性 ,分析开发潜力及剩余油分布特征 ,针对沙二上 2 + 3油藏大厚层内泥质条带多、厚度大、水驱动用不均的状况 ,采取以层内调剖堵水为主 ,结合配套的注采工艺技术来提高大厚层内的水驱波及体积 ,改善油藏开发效果 ,方案实施效果显著 ,注采剖面改善 ,水驱动用程度提高 。

This paper studies serious inner heterogeneous of layer of reservoir improving development effecting pathway, Application reservoir description studies sedimentary mini-faces, Quantity of reservoir heterogeneous, analyses development potential and distribution character of remanining oil, As to reservoir of pucheng S 2U 2+3 many trip of mud in big-thick layer. Thickness is thin. Water-driving is odds, the paper Applies profile control and water shutoff with injection-production technology, water driving oil volume of big-thick layer and development effecting has Improved. Project efecting was very well, injection-production profile is improved, water-driving recovery efficiency is increased.
