水驱砂岩油藏特高含水期优势通道定量描述方法研究的中期报告 摘要： 本研究旨在探讨水驱砂岩油藏特高含水期优势通道的定量描述方法。在前期研究的基础上，本文重点对用于描述水驱砂岩油藏优势通道的指标进行了探讨，并对水驱砂岩油藏特高含水期优势通道的定量描述方法进行了分析。研究发现，水驱砂岩油藏特高含水期的优势通道主要体现为成岩作用、油藏构造和地质构造三个方面。本研究将从这三个方面出发，选取与油藏产水关系关键的指标，对水驱砂岩油藏特高含水期优势通道进行定量描述。 关键词：水驱砂岩油藏；优势通道；特高含水期；定量描述方法；成岩作用；油藏构造；地质构造 目录： 1. 引言 2. 相关理论分析 2.1 水驱砂岩油藏优势通道 2.2 特高含水期的主要因素 3. 定量描述方法 3.1 成岩作用指标的选取 3.2 油藏构造指标的选取 3.3 地质构造指标的选取 4. 研究进展 5. 结论 参考文献 Abstract: The aim of this study is to explore the quantitative description method of the preferential channel in water-driven sandstone reservoirs with high water content. Based on the previous research, this paper focuses on the indicators used to describe the preferential channel in water-driven sandstone reservoirs and analyzes the quantitative description method of the preferential channel in water-driven sandstone reservoirs with high water content. The study found that the preferential channel in water-driven sandstone reservoirs with high water content is mainly reflected in diagenesis, reservoir structure and geological structure. This study will select key indicators related to oil production and water production from these three aspects to quantify the preferential channel in water-driven sandstone reservoirs with high water content.
