摘要:
邵伯、肖刘庄地区主要发育近岸水下扇沉积体系,黄珏、真武、曹庄地区发育扇三角洲沉积体系,邵伯、樊川深凹部位发育湖底扇。近岸水下扇控型圈闭成藏主要受沉积相带和储层物性控制,内扇、中扇、外扇均可成藏。扇三角洲沉积为陡坡带最主要的沉积体系,紧邻烃源岩,通过大断层和不整合面沟通油源,成藏条件优越。湖底扇圈闭在深凹带较为发育,其成藏主要受输导体系和储层物性控制,分析认为小断层、微裂缝是油气输导的主要通道。针对扇控型圈闭预测的两大难点——储层埋深跨度大、物性预测难,建立了“从扇体形态描述到定量预测再到物性预测”的扇控圈闭地震识别技术模式,识别出多个圈闭,实施钻探了多口探井,取得了良好的勘探效益。
Abstract:
The nearshore subaqueous fan deposition systems are mainly developed in the Shaobo and Xiaoliuzhuang area,the Huangjue,Zhenwu,and Caozhuang areas have fan delta sedimentary systems,and the Shaobo and Fanchuan deep depressions have lacustrine fans.The formation of underwater fan-controlled traps in the nearshore is mainly controlled by sedimentary facies and reservoir physical properties,and the inner,middle,and outer fans can form reservoirs. Fan delta in steep slope is the main depositional system,which is close to the source rocks,communicates with the oil source through large faults and unconformities,and has the superior conditions for forming reservoirs.The lacustrine fan traps are more developed in deep depressions,their accumulations are mainly controlled by the transmission system and reservoir physical properties.The analysis results show that small faults and microfractures are the main channels for oil and gas transmission.Aiming at the two major difficulties in the prediction of fan-controlled traps,such as large depth of the lay and hard to predict physical properties,it was established a technical model of seismic identification for fan-controlled traps from the description of fan body shape to quantitative prediction to physical property prediction,which identified a number of traps,drilled some exploratory wells,and has obtained good exploration effects.
