地震资料极性判别与道积分技术在渤中M油田的应用
摘要
渤中M油田的主力油层段埋藏较深,且地震资料主频较低,常规的反演技术应用效果较差。针对这些实际情况,结合储层均为砂、泥岩薄互层的特点,充分利用道积分技术不受钻井及构造解释影响、最大限度尊重原始地震资料的优势,更好地研究了M油田的储层展布。基于子波极性的精细分析及合成地震记录的验证,得到了与已钻井吻合度较高、能反映主要目的层段储层物性及厚度的道积分数据体;优选了该层段基于道积分数据体的正振幅之和作为敏感属性,准确预测了主力油层段储层的平面展布规律、调整井的储层厚度及油层厚度;在浅层通过优选基于道积分数据体的最小振幅属性,发现了一个成藏条件较好的河道砂体。经过井轨迹优化兼探该潜力砂体,新发现290×104 m3探明石油地质储量,在该砂体上投产的4口井使M油田的产量翻番,实现了油田的立体高效开发。
