针对辽河油田L区块的油藏条件,在室内进行深部调驱体系提高原油采收率的研究。实验首先对调驱用的聚合物从热稳定性和与交联剂的配伍性进行了筛选,得出了最佳的聚合物;并对对三种表交联剂进行了筛选;最后筛选出了最佳的配方。通过室内实验筛选出的体系封堵效率对高、中、低50.0%、21.4%、28.6%,低渗透驱油效率22.75。 Aiming at the reservoir condition of Block L in Liaohe Oilfield, a deep flooding system is used to increase oil recovery in the interior. First of all, experiments were carried out to screen the polymer used in the toner control from the thermal stability and the compatibility with the crosslinking agent to obtain the best polymer; the three kinds of crosslinking agents were screened; finally, The best recipe. The efficiency of system plugging efficiency was 50.0%, 21.4% and 28.6% for high, medium and low, and the efficiency of low permeability and flooding was 22.75.
