双高期油藏层内非均质对剩余油的影响及分析
|
摘要
针对辽河油田J1 6块油层厚度大,层内非均质严重的特点,通过地震精细解释,细分韵律段,构建等时地层格架,精细刻画了单砂体内部构架,研究表明,纵向剩余油集中在反韵律厚层的项部,主要受上部隔层、下部夹层及重力影响.2008年挖潜井在厚层顶部投产取得了较好的效果,说明对于双高期油藏层内非均质对剩余油的分布具有控制作用,这对进一步挖掘老区油藏潜力,提高采收率都具有很重要的意义.
Block J16 is a highly heterogeneous reservoir with thick oil layers.Based on seismic interpretation, meticulous study of rhythm has been carried out.An isochronous framework is established.Meticulous study on inner framework of monosandbody has been carried out.It objectively reveals that residual oil exits on the top of the antirhythm thick layer , mainly affected by the upper compartment, lower interlayer and gravity.The good results of potential wells at the top thick layer of production have been achieved in 2008.The results show that medium heterogeneity controls on the distribution of the residual oil in the mature field.This is of significant importance to tap the reservoir potential for EOR.
