摘要
注入压力上升是聚合物驱注入井最重要的动态变化之一，也是保证聚合物驱效果的重要影响因素。依据压力系统的变化特征对大庆油田南一区西东块注聚后注入参数进行优化调整，减少井间干扰。首先应用霍尔曲线斜率的变化对低压井和高压井进行初步的调整，再应用散点图法依据注入速度与注入压力的关系，合理调整注入压力，匹配注入参数。优化调整后，全区注入压力趋于均衡，注入参数与油层匹配性更好，油层动用程度提高。
The rise of injection pressure is one of the most important performances for polymer flooding, and it is also an important influencing factor to assure good results of polymer flooding. The optimized adjustment of the injection parameters after polymer flooding is conducted to reduce inter-well interference according to the change characteristics of the pressure system in East-west Fault-block of Nan No. 1 Block in Daqing Oilfield. Firstly, based on the slope changes of Hall curves, the initial adjustments are caught out for the wells with low and high- pressure; Then the injection pressures and matched injection parameters are properly adjusted by scatting diagram and the relation between the injection rates and their pressures. After optimized adjustment, the ＇injection pressure of the whole block tends to be balanced and the compatibility between the injection parameters and the oil layers is much better. Finally the development degree of these oil reservoirs is greatly improved.
