摘要
三北油田经过30年的开发,已进入高含水开发后期,开采难度大。针对这种情况,建议:1、继续进行降压开采;2、立足于层间轮采,对长期开采同一层位井,适时调层改采;3、高部位井可恢复生产,改变液流方向,调整平面上井间干扰;4、在轴部等剩余油地区恢复三类井;5、采取化堵、卡堵水等措施,解决井层间层内非均质性。
After 30 years development, later stage of high water-cut development has come. Oil production is difficult. Suggestions： 1. going on reducing the pressure and producing oil. 2. A rotary production in different layers is main production method. Meanwhile, exploitation in the same layer being exploited for a long period should be stopped. 3. To restore production of high-location well, change flow direction and adjust interfere between wells on the same surface. 4. To restore three kinds of wells in residual oil area located on the axle section. 5. To solve the aeolotropy between wells and formations through melt-shield and block-shield way.
