富泥型深水重力流沉积特征及沉积演化规律分析
A Study on the Sedimentary Characteristics and Evolution of Mud-rich Deepwater Turbidite Reservoir
摘要
Abstract
Located in the southern West African Basin,Z Oilfield has low net pay and low net-to-gross ratios,belonging to the mud-rich deep-water gravity-flow deposits.Based on the well penetrations,seismic attributes and production data,the facies types,sedimentary configuration boundaries of the Z Oilfield were identified.The facies distribution characteristics and sedimentary evolution of Z Oilfield were summarized,leading to the following conclusions:1)the Z Oilfield has developed main channel,levee,main lobe,lobe fringe,shale and slump;2)channel and lobe configuration boundaries were identified through changes in seismic axis strength,seismic amplitude attributes,and RGB frequency division attributes;3)for Z Oilfield,the bottom oil group developed unconfined channel-lobe system,dominated by lobes,transitioning upwards to confined channel systems,with strong vertical stacking of channels,and on the top oil groups weakly confined channel systems have developed,with stronger lateral migration,and smaller scales of individual channels.关键词
