大港油田滩海地区酸化工艺技术研究与应用

Acidification Technology Research and Application for Dagang Oilfield in Sea Beach Area

通过深入分析滩海油田储层的地质、流体、岩矿和储层所隐藏着的各种伤害机理,在理论分析、大量试验以及工艺方案的基础上,将类似油田和储层酸化实验研究有关的经验结合起来,全面且深入的对大港油田滩海地区酸化工艺技术进行了细致的研究,以此将与之相适应的配套技术提出来,并应用到具体的实践活动当中。酸化工艺的成功施工率与有效率都高达100%,极大的促进了增产效果的显著提升,进一步将油层中所包含的自然产能释放出来,有助于提高人们对于储层的认识程度。

Through the deep analysis of the geology,fluid and all the hidden damage mechanism in rock ore and reservoir of sea oilfield reservoir and on the basis of theoretical analysis,a large number of trials and technology solutions,this paper has combined the similar oilfields with the relevant experience of reservoir acidification experimental researches and carried on the detailed,comprehensive and in-depth study of the acidification technology for Dagang oilfield in beach area,on which basis,the corresponding supporting technologies have been pushed out and applied to the concrete practice.The success construction rate and efficiency rate of acidification technology are as high as100%,which has greatly promoted the significant increase of yield-increasing effect and further released the natural capacity contained in reservoir,besides,it is helpful for people to raise their awareness degree for the reservoir.
