摘要
陈家洼陷是辽河盆地西部凹陷内的一个生油洼陷,洼陷内沙三段下亚段发育有多套浊积砂体和厚层泥岩,具有自身发育地层岩性圈闭的条件。利用地震属性分析、地震分频处理和模型约束波阻抗反演等技术,对沙三段下亚段的砂体沉积规律和分布特征进行了分析和描述,预测了砂体分布的优势区。在此基础上,结合钻井、测井和岩心资料,对沙三段下亚段4~(th)SQ2和4~(th)SQ3层序顶界面的有利砂体进行了预测。结合沉积相划分结果,对沙三段下亚段地层岩性圈闭的形成模式进行了分析,预测了有利圈闭的分布区域。
Chenjia depression is the main oil source area in the west sag of Liaohe basin.Several series of turbidite sandbodies and huge thick mudstone are developed in its lower Sha3 sub-member.The depression has the condition of forming formation lithologic trap. Using the seismic attribute analysis,frequency division and model- based impedance inversion,the sedimentary laws and distribution characteristics of sandbody in lower Sha3 sub-member was de- scribed and analyzed,and the favorable area of sand distribution was forecasted.Based on the results,combined with the drilling, logging and core data,the beneficial sandbody of the top of 4~(th)SQ2 and 4~(th) SQ3 was identified.Referred with the division results of sedimentary faceis,the forming pattern of formation lithologic trap in lower Sha3 sub-member was analyzed,and the distribution of beneficial traps was predicted.
