摘要 在致密油藏进行储层改造酸化的过程中,酸液配方的不得当可能导致地层的堵塞,严重影响油藏的评价与开发,所以酸液的优选至关重要。为了优选出最佳的酸液配方,以长庆油田某区块岩心为例,对各种药剂的种类与浓度进行复配和筛选,最终优选出储层的高效酸液配方。实验结果表明:高效的酸液配方既能减小酸液对储层的伤害,也能提高近井地带储层的渗透率,达到油井高产、稳产、提高采收率的目的。 In the dense reservoir acidification process,improper acid liquid formulation may lead to the formation blockage,which will seriously affect the reservoir evaluation and development.So it is very important to choose proper acid liquid.In order to obtain the best acid liquid formulation,taking the core from a block of Changqing oilfield as an example,types and concentration of various agents were screened,finally optimized reservoir efficient acid liquid formulation was determined.The results show that,the efficient acid liquid formulation can decrease acid damage to reservoir,and improve the permeability of reservoir near the wellbore.
