蒙古林砂岩油藏是一中高渗透普通稠油油藏，地下原油粘度高达125mPa·S，储层非均质性强，水驱波及系数小，驱油效率低．该油藏89年10月全面投产投注，1995年12月6日正式开展注聚合物现场试验，注聚合物两年来，效果比较明显。在地下原油粘度大于100mPa·S的油藏中开展注聚合物试验，在国内外尚属首例，而且在注聚合物地面工艺上也进行了一些新的尝试。
The Mongolian sandstone reservoir is a medium-high permeability common heavy oil reservoir. The viscosity of underground crude oil is as high as 125 mPa · S. The reservoir heterogeneity is strong, the coefficient of water flooding is small, and the oil displacement efficiency is low. The reservoir was put into full operation in October 89. On December 6, 1995, a field test of polymer injection was officially launched. After polymer injection for two years, the effect was obvious. It is the first case at home and abroad to carry out polymer injection test in reservoirs with underground crude oil viscosity more than 100mPa · s. Some new attempts have also been made on polymer injection floor.
