摘要

摘要: 通过对江汉盆地潜江凹陷王-广-浩地区古近系潜江组潜4段0油组半咸化期砂岩储层的预测,形成了一套剖析盐湖盆地复杂岩性区储层的预测方法——"四定法"储层预测技术,即:地质地震复合相定相带、岩石物理建模定标志、多属性地质综合分析定边界、确定性反演定厚度。近3年来,采用"四定法"在潜江凹陷进行边研究、边实践、边总结,发现了多个高产滩坝岩性油藏,取得了较好的勘探效果。该方法的推广应用,可有效提高复杂岩性区储层预测的准确性。

Abstract: Sandstone reservoirs were predicted so as to propose a new method for the studies of reservoirs with complicated lithology in saline lake basins. The study area was the semi-saline period in the oil group no.0 in the fourth member of the Paleogene Qianjiang Formation (E_2q₄⁰) in areas W, G, and H in the Qianjiang Sag of Jianghan Basin. The method was called "four-definition", which defines sedimentary facies through integrating geologic data with seismic data, defines markers through petrophysical modeling, defines geological boundaries through comprehensive multi-attribute geological analysis, and defines stratigraphic thicknesses through definitive inversion. Applications in the Qianjiang Sag succeeded in finding several high-yielding oil pools of beach bar facies, showing that the method can improve the prediction accuracy in reservoirs with complicated lithology.
