摘要:
惠州A工区目前已有常规采集地震资料分辨率较低,导致目的层段薄层砂体接触关系难以确定,岩性圈闭边界线难以落实,小断层成像不清楚,难以满足勘探需求。在该工区进行了南海东部地区首次高密度三维地震采集试验,与常规拖缆采集地震相比,高密度采集方案电缆间距缩小至50 m,源缆的沉放深度浅放至5 m,电缆长度增加至5 100 m,采集方向垂直于砂体沉积展布方向; 从而缩小了采集面元,提高了覆盖次数,拓宽了地震频带。处理成果显示,高密度采集地震资料分辨率和成像质量有较大幅度提升,断层成像干脆,砂体展布轮廓清晰,井震标定吻合度更高。在高密度地震资料基础上进行了钻井,证实了构造和储层的预测精度更高,推动了该区的岩性圈闭勘探进程,为南海东部岩性圈闭勘探提供了问题解决思路和方案
