摘要
通过天然水驱和人工注水油藏的地质、开发实际资料对比,得出以下认识:1.天然水驱油藏的地质特点是含油面积小、流度大、天然能量充足;2.天然水驱油藏的开发特点是采油速度高、无水采收率高、最终采收率高;3.其开发效果好于人工注水油藏的原因是水驱波及系数和驱油效率均较高,其中驱油效率较高是主要的。
Following conclusion are reached by a comparison of actual geological and development data from a naturally water flooded and artificial water flooded oil reservoirs. 1. Naturally water flooded Oil reservoir is characterized geologically by small area, high K/u, and sufficientty active acquifer; 2. Naturally water flooded oil reservoir is characterized by high production rate, high water-free oil recovery and high ultimate oil recovery in its development. 3. The main reason why naturally flooded reservoir is superior to the artificially water flooded reservoir in their development is due to its high conformance and high displacement efficiency in which displacement efficiency is considered to be more important.
