摘要

本文介绍了Bazhenov页岩油层提高采收率方法(EOR)的综合研究进展。潜在的低渗透油藏有效技术正在研究中:以混相驱方式注入伴生油气开采轻质油;注入表面活性剂水溶液,从岩石中分离被吸附的碳氢化合物,改变岩心的润湿性;加热技术将固体碳氢化合物转化为液体和气体,并回收。该项目探索了潜在有效的EOR技术及其对Bazhenov页岩地层各种类型碳氢化合物的影响:封闭孔隙中的可动油、吸附和固体(干酪根)碳氢化合物。实验研究包括:气体组成的选择、表面活性剂组成的选择、过热注水热暴露可能性的研究。该项目目前正处于确定每种方法有效性的阶段,为特定的油田条件选择一种技术,并确定每种方法旨在提取的碳氢化合物资源。

A Comprehensive Project of Thermal, Gas and Chemical EOR Method Application for Bazhenov Shale Formation
The article describes the development aimed at a comprehensive study for enhanced oil recovery methods (EOR) of the Bazhenov shale oil formation. Potentially effective technologies for low-permeable reservoirs are under consideration: injection of associated petroleum gas in the mode of miscible displacement to recover light oil; injection of the surfactants water solutions, to separate sorbed hydrocarbons from the rock and change core wettability; and heating technologies to convert solid hydrocarbons into liquid and gaseous, and recover. The project explore potentially effective EOR technologies and their influence on the various types of hydrocarbons of the shale Bazhenov formation: mobile oil in closed pores, sorbed and solid (kerogen) hydrocarbons. Experimental studies were carried out: the selection of the gases composition, the selection of surfactant compositions, the study of the possibility of thermal exposure by over-heated water injection. The project is currently at the stage of determining the effectiveness of each method, selecting a technology for specific field conditions and identifying which hydrocarbon resources each method is aimed at extracting.
