Analysis of Suitability for Two Types of Reservoirs by MEOR

Abstract

Abstract: The microbial treatment and pilot test of two different types of low permeability reservoirs were conducted by cooperation of No.3 Production Plant of Xinjiang Oilield Company with NPC Mictobial Company. USA. The results showed that the glutenite reservoir of Middle Triassic in District No, 1 west had mueb more responses than that of the fractured basement reservoir of Carboniferous in District No.1. This pa-per analyzes the effect of diferences among permeability, porosity, salinity and percolation mechanism for low permeabilily reservoirs on micro-bial recovery process, proposes some proper regulation measures for special reservoirs, and makes suggestions for optinmum processing progrurn and introducing real-time monitoring techniques.

Key words: MEOR, EOR, reservoir type, pilot lest
