摘要
从沉积相及构造的基础上,研究了该区块的储层特征;着重进行了储层敏感性实验,对注水过程中的储层损害的主要因素进行了分析,实验最终表明对于大路沟一区储层,盐敏和水敏在注水过程中造成的损害较为明显。进而,提出该区块保护储层的相应措施,比如高能气体压裂,小型酸化等措施。
Studied the reservoir characteristics bases on the sedimentary context and geological structure, focused on the experiment of reservoir sensitivity and analysis about the key factors of reservoir damage during the water infection process. The result of the experiments finally indicated that the salt sensitivity and water sensitivity had more obvious damage of DALUGOU first area. The paper proposed some measures to reservoir protection during the process of water infection, for instance, high energy gas fracture, washing with acid and so on.
