摘要
红南油田2块白垩系三十里大墩组油藏开发历史长,水淹状况严重,地质情况复杂。原有综合调整方案需要在后期大量监测及措施基础上进一步优化调整。在油藏开采过程中,很难判断是放大生产压差带来的底水锥进还是边底水沿裂缝窜进,因此也存在进一步深化认识的可能性。在精细地质研究的基础上,深入研究了油藏油水运动规律,总结了水淹规律及影响因素,分析了油藏不同地区产水规律及来源,进而开展了剩余油分布规律研究和综合调整方案研究,有针对性地提出了调整方案。
It had a long oilfield development history of Cretaceous reservoirs in Sanshilidadun Formation of Block 2of Hongnan Oilfield,where serious reservoir water-flooding was induced with complex geologic conditions.The original comprehensive reservoir adjustment scheme needed to be further optimized based on wide monitoring and stimulation at the late stage.In reservoir development,it was hard to judge if the coning of bottom-water was induced by pressure difference in production or the bottom-water channeling along the fractures,therefore there was a possibility of deepening understanding of it.On the basis of fine geologic study,the law of oil-water movement in the reservoirs is deeply studied,the influential factors of water-flooding are summed up.The rules and resources of water production from different areas are analyzed.Consequently the remaining oil distribution rules and its adjustment scheme are studied,by which a new adjustment program is put forward.
