摘要
With multiple sources and multiple stages for strike-slip,the Moliqing Fault Basin has a complicated fracture pattern,and the source stage and reserve distribution still remain discussing.By means of high-resolution sequence stratigraphy,combining lithologic,electric and seismic data together,the 2nd member of the Shuangyang Formation in the Moliqing Oilfield has been divided into 4 4th-grade sequences(equivalent to mid-term base-level cycles) and 13 short-term base-level cycles.A high-resolution sequence stratigraphy framework of the Moliqing Oilfield has been established.Grain size,seismic attribute and facies analyses have been applied to study sediment-ary micro-facies.Using facies-constrained stochastic modeling method,the reservoir distributing features of high-exploitation blocks A and B have been fitted and the optimal parameters and models have been selected.Then these parameters are applied to the reservoir prediction in blocks C and D which are in low exploitation degree.Six oil-bearing reservoirs in the 2nd member of the Shuangyang Formation in the south of block C have been predicted with this method.The change from qualitative analysis to semi-quantitative and quantitative analyses in reservoir research provides more reliable foundation for the exploration and development of lithologic reservoirs.
