In this paper, core, grain size, drilling and production data are used to study the sandbody architectural characteristics of lake turbidite channel reservoirs and its influence on development and production, taking mid-Shahejie3 member in He 146 well block of Xianhe oildom in Dongying sag as an example.This study shows that the turbidite-channel configuration can be divided into the 7levels:bedding, bedding group, single channel superposition of filling body or micro events, single channel, channel belt, channel complex and channel complex set.Meanwhile, we mainly discus the configuration mode of turbidite channel by local dense well pattern and production performance data:the single turbidity channel is 120.0～450.0mwide, with the angle of 0.9°～2.4°in its bottom, and the variation of the thickness of single turbidity channel has a significant exponential relationship with the extension distance.The lateral migration of the sliding turbidity channel is obvious.The smaller the distance between the oil and water wells in the paleo current direction, the better the production effect is.When oil wells and injection wells are located on the side edges of different single channels, the remaining oil is enriched between oil and injection wells.The results of this paper have important guiding significance for enriching the quantitative study of turbidite channel configuration and the adjustment of development countermeasures.%以东营凹陷现河油区河146井区沙三中亚段湖泊相浊积水道储层为例,利用岩心、钻井资料及生产数据等,根据沉积体内部构型单元结构层次特征,将研究区浊积水道构型单元划分为七级,分别为层理、层理组、单一浊积水道内部侧积或加积单元、单一浊积水道、浊积水道带、浊积水道复合体及其组合,分析浊积水道储层构型特征及其对开发生产的影响.结果表明:研究区浊积水道储层构型以单一浊积水道为主,单一浊积水道宽度为120.0～450.0m,水道底部倾角为0.9°～2.4°;浊积水道厚度变化与延伸距离具有较明显指数关系,浊积水道侧向迁移明显;在古水流方向上投影距离小的注采井距生产效果较好;油水井位于不同单一浊积水道侧缘时,油水井间剩余油富集.该结果对浊积水道构型定量研究及开发对策调整具有指导意义.
