摘　　要：针对某稠油田含水上升快的问题进行弱凝胶调驱井组试验。研究表明,与注水井酸化联合作业,能够改善层间吸水不均,缓解平面矛盾,改变注入水驱替方向,可显著改善注入水沿优势通道突进的现象。如果注凝胶前主力出水层位为主要产出层,笼统注入凝胶时要考虑对注水量进行调整,避免因注凝胶造成主力层位吸水不足导致地层压力下降,从而影响油井供液能力。Aimed at water cut going up quickly,the experiment of weak gel profile control is applied in well group.The research reveals that weak gel profile control combined with acidification can improve water injection profile,relief plane water flood conflict,change the flow direction of water flood,and enhance the water flooding effect obviously.Furthermore,the research results also reveal that if the major producing zone is the main water producing zone before injecting weak gel,the water injection needs be optimized during commingling weak gel injection,so as to avoid lack of water injection in the main producing zones results in the decreasing of formation pressure and influence the oil well yields.
