Abstract
To develop new technology and advanced approaches to reduce viscosity of crude oil reservoirs, increase permeability and improve flow rate of high viscous light oil reservoir, and then further improve recovery of block with more intensive well network, steam-flooding pilot studies were implemented from 2006 to 2008. Based on the formation nature characterized of high viscosity, low permeability, high clay content, and thin effective thickness, in-house physical modeling was undertaken in feasibility study; steam injection parameters and injection methods were optimized with numerical simulation; ground anti-swelling and wellbore heat insulation technologies were carried out; field tests included 3 wells, and cumulative increase of recovery was 1.81×104 t. The studies indicated suitable reservoir geological conditions for steam-flooding extraction of low permeable high viscous light oil reservoir.
