摘　　要：探井在钻井、完井过程中,其储层不可避免地受到钻井液、完井液的伤害,因而必须进行改造以解除伤害、还储层原始面目,同时加深对储层的认识,获取储层的相关资料,为下一步勘探、开发打下良好的基础。探井增产酸化针对新区、新层的资料有限,而钻井试油时间要求快,改造的效果也就有好、有差。在对近两年探井增产酸化工艺涉及到的情况进行总结的基础上,分析了影响探井增产酸化效果的因素,针对性地提出了探井增产酸化工作建议,有助于提高探井增产酸化作业效果。During the drilling and completion works in an exploratory well, reservoirs will be inevitably damaged by drilling or completion fluids. The reservoirs must be rehabilitated to relieve from damage and regain their original features, and so a deeper knowledge and the related data can be obtained from those reservoirs for a good start of further exploration and development in this area. However, for the lack of information on new reservoirs in a new exploration block, acid stimulation will be significantly influenced also by early production test within a short time. This study summarized how the acid stimulation technology has been used in recent two years, then analyzed what factors can affect the results of acid stimulation, and finally put forward some positive suggestions on how to improve the effects of acid stimulation technology applied in exploratory wells.
