摘要:
GS油田中浅层N1-N21油藏经过20多年的注水开发已进入中高含水期,油藏水淹严重剩余油分布复杂,准确评价水淹层确定剩余油富集区是油田开发面临的首要问题。以岩石物理实验与测井资料为基础,明确研究区水淹机理与水淹特征,建立水线法与流体替换法求取油藏原始储层参数,提高水淹层定性识别的精度; 在相渗实验基础上,建立产水率计算模型,形成水淹层6级划分标准,实现水淹层分级解释定量评价。通过现场实际应用,该方法可以有效识别水淹层,提高水淹层的解释精度,水淹级别解释与生产测试结论更加吻合。不同的水淹层解释方法都有区域适用条件,准确求取残余油饱和度、束缚水饱和度、含水饱和度与产水率是水淹层定量评价的基础,但对于低矿化度水淹层电性特征接近于原始油藏电阻率的储层目前没有较好的方法解决。
Abstract:
After more than 20 years of water injection development in GS oilfield, the middle and shallow N1-N21 reservoirs in GS oilfield have entered the medium and high water-cut period, their reservoir flooding was serious, and the residual oil distribution was complex, so it is the primary problem for oilfield development to accurately evaluate the residual oil enrichment area in the water flooded layer. In order to solve this problem, based on the rock physics experiment and logging data, the water flooding mechanism and flooding characteristics in the study area were determined, the waterline method and the fluid replacement method were established to obtain the reservoir original reservoir parameters, which improved the accuracy of the qualitative identification of the flooded layer. In addition, on the basis of phase seepage experiment, the calculation model of water production rate was established, the standard of 6 classification of flooded layer was formed, and the quantitative evaluation of the classification interpretation of flooded layer was realized. Through the practical application in the field, this method can effectively identify the flooded layer, improve the interpretation accuracy of the flooded layer, and the interpretation of the water flooding level was better consistent with the conclusion of the production test. Different interpretation methods of flooded layer have regional applicable conditions, accurate extraction of residual oil saturation, bound water saturation, water saturation and water yield were the basis of quantitative evaluation of flooded layer, but for low salinity flooded layer, because its electrical characteristics were close to the original reservoir resistivity, there is no better method to solve so far.
