湖泊相浊积水道储层构型特征及其对开发生产的影响——以东营凹陷现河油区河146井区沙三中亚段为例
Architectural characteristic of lacustrine turbidite channel and its impact on development and production:taking the mid-Shahejie3 member in He 146 well block of Xianhe oildom of Dongying sag as an example
摘要
Abstract
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.关键词
