波阻抗反演是高精度储层参数反演技术的核心环节,也就是如何将测井资料的声波时差和密度与地震资料有机结合起来,核心就是测井资料的具体应用。而文东油田具有砂体单层厚度薄、横向连续性差、地震反射紊乱等特征,只采用常规的储层研究方法很难得到好的研究结果。针对这一问题,利用储层随机建模预测研究等配套关键技术进行砂体分布特征研究,并对典型单砂体进行了预测,为油气储量评价及调整挖潜提供了依据。
Wave impedance inversion is the core of high-precision inversion of reservoir parameters. That is, how to combine the acoustic time difference and density of logging data with seismic data, and the core is the application of logging data. The Wendong oilfield has the characteristics of thin monolayer thickness, poor lateral continuity and seismic reflection disturbance. It is difficult to get good results by conventional reservoir research methods. In response to this problem, we have studied the distribution characteristics of sandbodies by using the key technologies such as stochastic modeling and prediction of reservoir, predicted the typical sandbodies, and provided evidences for the evaluation and adjustment of potential reserves.
