求翻译：后续水驱开始后，含水继续下降，在注入0.382PV时，含水下降到最低点78.7％，含水最大降幅14.7个百分点。随着含水量的下降，试验区产油量逐步提高，聚合物注入结束时，产油量上升到注聚前的1.2倍，后续水驱含水下降到最低点时，产油量上升到聚驱前的2.0倍。试验区阶段累积增油0.7566×104t，提高采收率4.52%。根据数值模拟结果，盐上油藏聚合物驱最终采收率提高值为6.0个百分点。是什么意思？

After the start of water flooding, water continues to drop, in injected 0.382pv, the moisture content down to the lowest point of 78.7%, water the largest decline of 14.7 percentage points. With the decline in water content, the oil production of the test area gradually increased, the end of the pol

Follow-up after the start, the drive to continue to decline in fuel injection, in 0.382 PV water fall, 78.7 % to the lowest level, the largest water fall of 14.7 per 100 points.

After the following water drive starts, the watery continues to drop, when pours into 0.382PV, the watery drops to the perigee 78.7%, watery maximum range of fall 14.7 percentage points.Along with the water content drop, the pilot area oil offtake enhances gradually, when the polymer pours into the

Follow-up water drive after starting, water continued to fall, into the 0.382PV, the water fell to the lowest point 78.7%, water per cent 14.7%. As the water falls, test area oil production gradually increased, at the end of polymer injection, oil production increased by 1.2 times before to polymer
