渤海JZ-X气田湖底扇岩性油气藏预测技术研究
Research on Prediction Technology of the Lithological Reservoir of Sublacustrine Fan in Bohai JZ-X Gasfield
摘要
Abstract
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 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.关键词
