摘要:
GS油田中淺層N1-N21油藏經過20多年的注水開發已進入中高含水期,油藏水淹嚴重剩余油分布復雜,準確評價水淹層確定剩余油富集區是油田開發面臨的首要問題。以巖石物理實驗與測井資料為基礎,明確研究區水淹機理與水淹特征,建立水線法與流體替換法求取油藏原始儲層參數,提高水淹層定性識別的精度; 在相滲實驗基礎上,建立產水率計算模型,形成水淹層6級劃分標準,實現水淹層分級解釋定量評價。通過現場實際應用,該方法可以有效識別水淹層,提高水淹層的解釋精度,水淹級別解釋與生產測試結論更加吻合。不同的水淹層解釋方法都有區域適用條件,準確求取殘余油飽和度、束縛水飽和度、含水飽和度與產水率是水淹層定量評價的基礎,但對于低礦化度水淹層電性特征接近于原始油藏電阻率的儲層目前沒有較好的方法解決。
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.
