摘要
砂砾岩储层因其具有近物源、断裂多期活动等特点,使其成为凹陷陡坡带重要的油气勘探目标之一。通过对东营凹陷MF地区进行层序地层分析,根据地震剖面反射特征,将Es4上亚段划分为5个长期基准面旋回,结合地震多属性分析和波阻抗反演技术,最终在Es4上亚段识别出5套有利砂砾岩体。通过对MF地区砂砾岩储层研究的勘探实践,总结出砂砾岩储层勘探的三要素,高分辨率地震资料是寻找砂砾岩扇体的基础,层序地层学是寻找砂砾岩扇体的理论指导,地震储层预测技术是寻找砂砾岩扇体的有效手段。
Glutenite reservoirs in the abrupt slope zone was an important exploration target ,because it was near the source and had multi-phase activity characteristics,etc。The upper member of Es4 was divided into 5 long-term base level cycles by analyzing the sequence stratigraphy in MF Area and based on the character of seismic profile reflection.Eventually five sets of favorable glutenite reservoirs were identified in combination with exploration of the glutenite reservoirs in MF Area ,3 factors of glutenite reservoir exploration were summarized. It shows that high resolution seismic data are the basis for searching for the glutenite fan ,the sequence stratigraphy is the theoretical guidance for searching for the glutenite fan,seismic reservoir prediction technology is an effective means to looking for glutenite fan.
