石油地质勘探与储层评价的具体方法

Specific Methods of Petroleum Geological Exploration and Reservoir Evaluation

伴随着中国石油勘查技术的快速进步,石油行业呈上升发展趋势,取得了较为优异的成绩,但在地质勘探和储层评价层面上探索的力度还不够,整体发展水准还比较欠缺。在当前全球石油资源愈加匮乏的背景下,石油开采业遇到了困境,如果还只是运用传统的技术很难得到长足的发展和进步。所以,应积极提高石油地质勘查水平能力,从根源上满足中国石油开采业发展的基本需要。基于此,文章首先介绍了石油地质勘探基本概况和内容;其次描述了石油地质勘查实际状况和发展前景以及勘探存在的问题和策略,阐述了石油地质勘探技术要点,如:测井技术、物探技术和钻井技术;最后提出了石油储层评价的具体方法,包括:欠平衡钻井、综合分类、整体定量等,同时还介绍了具体的案例。

With the rapid development of petroleum exploration technology in China,the petroleum industry is on the rise and has made excellent achievements.However,the exploration efforts in geological exploration and reservoir evaluation are not enough,and the overall development level is still relatively short.In the context of the increasing shortage of global oil resources,the oil exploitation industry has encountered difficulties,and it is difficult to achieve substantial development and progress ifit only uses traditional technology.Therefore,we should actively improve the ability of petroleum geological exploration to meet the basic needs of the development of petroleum exploitation from the root.Based on this,the paper first introduces the basic situation and content of petroleum geological exploration;Secondly,it describes the actual situation and development prospect of petroleum geological exploration,as well as the existing problems and strategies of exploration,and expounds the key points of petroleum geological exploration technology,such as logging technology,geophysical exploration technology and drilling technology.Finally,the concrete methods of oil reservoir evaluation are put forward,including underbalanced drilling,comprehensive classification,integral quantification,etc.At the same time,concrete cases are introduced.
