测井资料在文东油田储层预测中的研究与应用
|
摘要
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 key of high-precision reservoir parameters inversion technology which is how the acoustic time and density logging data cmbine with seismic data. The core is specific application of well logging data.As Wendong oilfield has characteristics of thin single-layer sand body, poor lateral continuity and seismic reflection disorder,etc., it is difficult to obtain good result by using only traditional research methods.To solve this problem, reservoir random modeling prediction researches combined with key technologies are used to study the distributional characteristics of the sand body, and typical single sand body was forecast. It provided a basis for the evaluation and adjustment of tapping the potential of oil and gas reserves.
