摘要
孔西斜坡勘探程度较低,储层类型较为复杂,且横向、纵向变化较大。通过分析该区地震、地质、测井等资料,多参数联合,建立不同岩性储层识别标准,以正演模型为指导,开展地震储层预测研究,定性、定量的描述储层在横向、纵向上的展布。通过该方法对孔西斜坡油页岩发育区的砂体进行描述、确定了致密油勘探潜力区带,取得了较好的效果。有利于指导油页岩发育段内部泥质粉砂岩等致密储层识别与评价,对类型油藏的研究具有一定的借鉴意义。
The reservoir in Kong Xi slope is complicated with lateral, longitudinal variation, which leads to less exploration. Different identification criteria of lithologic reservoirs are established through the analysis of seismic, geological and logging data and multi-parameter joint. Guided by the forward model, seismic reservoir prediction researches are carried out to qualitatively and quantitatively describe reservoir in the horizontal and vertical distribution. The method is used to describe the sand body of shale development zone in Kongxi slope, determine the potential exploration zone of tight oil successfully. It proves to be useful for identification and evaluation of tight oil reservoirs such as argillaceous siltstone in the oil shale developing section.
