摘要
Abstract
Some experiments on seven schemes of CC2 injection are conducted using heavy oil with 100 mPa-s viscosity to evaluate the effect for enhancing oil recovery with CO2 in heavy oil reservoir under reservoir condition. The schemes include GO2 huff-n-puff, CO2 huff-n-puff followed by CO2 and water drive, CO2 huff-n-puff followed by water drive, water alternating CO2 injection (WAG), water drive, CO2 drive, displacement of CO2 slug by water. It is found that WAG and huffn-puff followed by water drive are the two best injection modes for heavy oil reservoir with viscocity of 100 mpa·s. It is conduded that CO2 huff-n-puff followed by water drive is a potential engineering scheme forimproving oil recovery.关键词
