    GEOPHYSICS TECHNOLOGY FOR FINE DESCRIPTION OFDEEP WATER RESERVOIR AND ITS APPLICATION

    • 摘要: 沉积储层识别与精细描述是深水区油气藏勘探的重点及难点。针对深水沉积砂体内部储层横向变化快、纵向多期叠置切割、非均质性强等储层预测及评价难题,提出了利用地震甜点/梯度融合属性定性识别沉积体,高精度频谱成像精细雕刻沉积体内幕,多相约束随机地质建模实现储层精细描述的技术方案,实现了储层定性分析向半定量评价转变,解决了深水沉积体识别与储层精细评价难题,对加快复杂深水碎屑岩油气藏勘探步伐具有积极的推进作用。

       

      Abstract: Reservoir recognition and fine description are critical to oil and gas exploration in deep water area. It is rather difficult task since reservoirs are always changing rapidly in lateral, multiphase superimposed vertically and strongly anisotropic. To solve those problems in reservoir prediction and evaluation, this paper adopts high precision spectral imaging and multiphase constraining random geologic modeling as tools to improve the interpretation from qualitative to semi-quantitative and to solve the problems encountered in recognition of deep water sedimentary bodies and reservoir evaluation.
