大庆油田正在进行全面加密井网的调整工作。针对差油层的加密井网,采用哪一种注水方式更有利呢?本文认为采用五点法面积注水方式较好。因为:1)可获得较高的水驱控制程度以及使油井多方向受效;2)可以满足对差油层进行强化开采的需要;3)从注采平衡的角度分析,五点法注水方式也是有利的;4)国内外的研究都表明,五点法井网的开发指标高于其它注水方式;5)可以满足调整井网在整个开采期内不断提高采液量的需要。大庆油田近两年的一些加密调整方案中已开始推荐五点法注水方式。
Daqing Oilfield is underway to complete the adjustment of the well network. For the poor oil well formation of the well pattern, what kind of water injection method is more advantageous? This article that the use of five points area injection method is better. Because: 1) can obtain a higher degree of waterflood control and multi-directional wells to be effective; 2) to meet the needs of enhanced oil recovery poor reservoir; 3) from the injection and production balance point of view, five-point method is 4) Both domestic and international research shows that the development index of the five-point well pattern is higher than that of other water injection patterns; and 5) It can meet the need of adjusting the well pattern to continuously increase the production volume during the entire mining period. Daqing Oilfield in recent years some of the encryption adjustment program has begun to recommend five-point method of water injection.
