井震联合在陆相三角洲前缘储层预测中的应用——以太北开发区为例
|
摘要
陆相三角洲前缘储层砂体薄,河道砂体窄小且分布零散,单一技术难以准确刻画砂体边界及井网控制不住的窄小河道砂体。优选了区分砂泥岩明显的自然电位(Usp)曲线并用其重构拟波阻抗曲线,应用地震特征参数反演结果的高频部分,与Inver TracePlus反演相结合来拓宽反演结果的频带,提高了地震纵向上小层的识别能力。编制了井震联合绘制沉积微相图流程,对太北开发区葡萄花油层组Ⅰ层三角洲前缘相储层进行了再认识研究,砂体变化体现在宽带状分布的河道砂体分叉增多,窄条带状分布的河道砂体连续性变差,这些认识在补充调整井部署中得到了应用和验证。
In continental delta front,reservoir sand body was thin,channel sand body was narrow and scattered,a single technique was difficult to accurately depict the sand body boundary and narrow channel sand body under the control of well pattern.A spontaneous potential curve was chosen for obviously distinguishing sand shale and reconstructing wave impedance curve for filtering,the high frequency inversion result of seismic characteristic parameters was used to widen the inversion results of frequency band,improve the recognition ability of the seismic vertical small layers in combination with InverTrace Plus inversion.A flow process is compiled for the sedimentary microfacies figure with well-seism combination,reservoirs in PⅠdelta front facies in Taibei Development Zone are recognized,sand body changes present wide distributive channel sand body with bifurcation increase,continuity of narrow ribbon distributive channel sand body becomes poor,these understandings are used and proven in the supplement and deployment of adjustment wells.
