【摘要】 用地震振幅属性分析、频谱分解和三维可视化等技术手段,对牙哈地区康村组和库车组河道砂体的展布进行刻画,用波阻抗反演技术对第三系砂体进行储层预测。结合油气成藏条件分析认为:下第三系油气成藏条件最有利,建议加深YH16井探测岩性体的含油气性;吉迪克组上砂岩段和下第三系内幕砂岩段是现实的勘探目标;康村组和库车组底部的河道砂体是良好的前景勘探目标。更多还原

【Abstract】 Based on seismic amplitude attribute analysis, spectrum decomposition, 3d visualization and other technical means, the distribution of channel sand bodies in Kangcui Formation and Kuche Formation were delineated, by using wave impedance inversion technique the Tertiary sand bodies were predicted. By integrating hydrocarbon accumulation conditions, the following conclusions were reached: (1)The targets is Lower Tertiary are most favorite ones, so continuing the YH-16 well’s further drilling to detect the hydrocarbon potential of the lithologic bodies is suggested. (2)Upper sand interval in Jidike Formation and the Inner sand interval in Lower Tertiary are current exploration targets. (3)The channel sand bodies in Kangcui Formation and Kuche Formation are the excellent future exploration targets.更多还原
