由于常规预前置液对地层造成损害，通过室内试验研制出了低损害压裂预前置液ZY－9601，文中主要介绍了ZY－9601的破乳效果、表面活性和对地层原始渗透率的影响，以及不同条件下的适应性。现场应用表明，该产品能有效防止地层损害，达到一定的增产目的。
As a result of conventional pre-fluid damage to the formation, through the laboratory test developed a low damage fracturing pre-fluid ZY-9601, the article describes the ZY-9601 demulsification effect, surface activity and permeability of the original formation Influence, and adaptability under different conditions. Field application shows that the product can effectively prevent stratigraphic damage, to achieve a certain increase in production.
