Research on Microscopic Characteristics of Remaining Oil Distribution after Strong Alkali ASP Flooding by Laser Scanning Confocal Technology

Abstract:

Different types of micro-pore structure and variation characteristics after long-term washing have a greater impact on micro-remaining-oil migration direction, distribution and content. This article applied Confocal Laser Scanning Technology to study reservoir fluid property and remaining oil micro distribution after strong alkali ASP flooding. Comparing the Laser Confocal analysis pictures of natural core after water drive and ASP flooding, coming to the conclusions that strong alkali ASP flooding sweep out larger amounts of heavy oil than water drive. Counting the ratio of different types micro-remaining-oil, and analysing on the displacement effects and mechanism of different types remaining oil after strong alkali ASP flooding.
