相控储层预测技术在五_2东克上组扩边中的应用
|
摘要
结合区域地质背景,利用地震,测井,录井资料与含油气性分析了五2东克上组地层特征,并对克上组5个砂层进行层序地层划分对比。受地震资料分辨率的影响,据含油气情况将砂层合并为T2k25、T2k23+4、T2k21+2三个砂层组反演预测和沉积相分析,认为克上组发育辫状河三角洲沉积体系。沉积相控制下的优质砂体展布与富油气带密切相关,2013年五2东难采储量区方案的实施取得良好效果进一步验证了相控储层与油气,在此基础上预测各层砂体的下步有利滚动扩边区。
Combined with regional geological background,using seismic,logging,well logging date and hydrocarbon bearing interval,the stratigraphic characteristics of upper karamay group in East five2 thare analyzed,and five sand units in group have the sequence stratigraphic classified and correlated.Affected by the seismic resolution and hydrocarbon formation,Upper karamay group is divided into T2k25、T2k23 + 4、T2k21 + 2sand groups for inversion prediction and sedimentary facies analysis,then it developed the braided river delta sedimentary system in this area.The high-quality sand body distribution is controled by sedimentary facies,and it's related to the rich oil zone.The implementation of the East five2th's difficult recoverable reserves had achieved good results in 2013,which had verified the eonclusion.Also the extension area of the each layer sand had been predicted by the research.
