针对裂缝性油藏,提出了预交联凝胶颗粒调剖剂。研究了预交联凝胶颗粒与裂缝宽度的匹配关系,以及表活剂对调驱体系的影响,通过驱油实验评价了体系在裂缝中的调驱性能。结果表明,预交联凝胶颗粒对裂缝性油藏具有较好的调驱效果,加入表面活性剂以后,预交联凝胶颗粒的弹性减弱,预交联凝胶颗粒能够运移至裂缝深处,预交联凝胶颗粒-表面活性剂体系能够在水驱基础上可提高裂缝岩心采收率13%~14%。 For fractured reservoirs, pre-crosslinked gel particle profile control agent is proposed. The matching relationship between the pre-crosslinked gel particles and the width of the crack and the effect of the surfactant on the flooding system were studied. The flooding performance of the system in fractures was evaluated by flooding experiments. The results show that the pre-crosslinked gel particles have better regulative effect on fractured reservoirs. After addition of surfactants, the elasticity of the pre-crosslinked gel particles is weakened and the pre-crosslinked gel particles can migrate to the crack depth , The pre-crosslinked gel particle-surfactant system can improve fracture recovery by 13% -14% based on water flooding.
