- 摘要:
准确预测油气藏的储层展布规律对油气勘探、开发十分重要。依据地震沉积学理论,对JZ-X气田原始地震资料进行分频处理,提高目标体识别精度;通过精细小层划分与对比和地层切片技术建立等时研究单元;在此基础上对湖底扇沉积特征进行深入研究,提出了基于沉积特征差异的地震属性优选思路,创新性地利用方差体地震属性代替原始传统成果数据,较好地刻画出湖底扇岩性油气藏的平面展布规律和垂向演化特征。研究成果为JZ-X气田后期开发方案调整提供了可靠地质依据。
It is very important for oil and gas exploration and development to accurately predict the reservoir distribution rules. Under the guidance of the theory of seismic sedimentology, we improve the resolution of conventional main frequency seismic profiles by means of seismic frequency division interpretation techniques. The research unit is established by fine layer partition and contrast and stratigraphic slice technology.Through the study of the in-depth study of sublacustrine fan sedimentary characteristics, the seismic attribute optimization based on sedimentary characteristics difference is proposed,and the innovative use of variance of seismic attributes is adopted to replace the original traditional result data, which can better depict sublacustrine fan lithologic reservoir plane distribution and vertical evolution characteristics.This study provides reliable geological basis for the later development plan research of JZ-X gasfield.
