摘要
吐哈油田是早期注水开发的低渗透油田,经过几年的开发,取得了良好的经济效益,但目前平面和剖面矛盾越来越突出,严重影响油田开发效果,为此,调剖技术作为综合治理的重要手段之一应该受到足够的重视。本研究结合油田的特点,研究出了以金属盐"YL"作为交联剂的延迟交联粘弹调剖剂配方,并在现场进行了推广应用,取得了良好的效果。
Tuha Oil Field is an early water-flooding oilfield with lower permeabilities.Through years' development,very good economic benefits have been obtained.But,the contradictions inside and between the layers have become more serious so that the Oilfield could not get good development results.Therefore,we' ve had to stress the importance of the injection profile adjustment technology since it is an important means of comprehensive treatments.Based on the characteristics of the oil field,this paper searched out a prescription taken YL as the cross-linker for the time-delay injection adjustment crosslinkers and had it used at the site,very good results have been obtained.
