截至2012年底,胜利油田已有70个油田累计已开发储量43.59亿吨。经过多年的开发,增加了大量的地震、钻井和开发动态等资料,新资料证实个别已开发区块的储量状况和开发状况存在矛盾,或储量计算参数有明显变化,需进行储量复算。初步分析影响储量变化的主要原因是通过对油藏地质的重新认识,含油面积、有效厚度、孔隙度、含油饱和度发生了显著变化。通过典型区块分析,提出了储量复算过程中应注意的问题,对今后的储量复算工作具有一定的指导意义。
As of the end of 2012, Shengli Oilfield has accumulatively developed reserves of 4.359 billion tons in 70 fields. After years of development, a great deal of information on earthquakes, drilling and development has been added. The new data confirm that there are contradictions between the reserves and developments of individual developed blocks or that there are obvious changes in reserves calculation parameters. The main reason for the preliminary analysis of the changes in reserves is that through the re-understanding of the reservoir geology, the oil-bearing area, effective thickness, porosity and oil saturation have undergone significant changes. Through the typical block analysis, the problems that should be paid attention to in the process of reserve recalculation are put forward, which is of guiding significance for the future recalculation of reserves.
