摘要:
采用双岩心流动试验方法,首次就温度、渗透率倍数、酸液配方以及注酸排量4个因素对转向酸转向性能的影响进行了研究。研究结果表明,酸液的转向范围及转向程度随温度、渗透率倍数的升高而降低;随配方中转向剂加量的增加而提高;不同的注酸排量影响酸液的转向性能;排量较小时,适当地提高排量利于提高其转向效果,而排量太大可能对转向不利。

Abstract:
The diverting performance influence factors in temperature,permeability multiple,acid formula and the injection flow rate of the self-diverting acid with double-core flow test are studied.The experimental results show that the diverting range and diverting extent decrease with increasing of the temperature and permeability multiple,and will improve with increasing of the adding amount of diverting agent.The different injection flow rate also affects the diverting performance,when the flow rate is low,the flow rate increasing is beneficial to improve the diverting effect,on the contrary,if the flow rate is too high,it will be disadvantageous to the diverting performance.
Key words:  diverting acid  diverting performance  influence factor
