Application of filtration control and deep-penetrating variable-viscosity acid fracturing technologies;
滤失控制与变粘酸深穿透酸压工艺技术的应用
New variable-viscosity acid has been studied and introduced into Tahe oilfield since 2004, conventional acid-fracturing techniques were broke through and good retardation and deep penetration of the acid were achieved.
塔河油田2004年以来研究和引进新型变粘酸体系并突破常规酸压工艺,实现了酸液缓速和深穿透的目的。
