资源与目标一体化评价技术及其勘探意义

资源与目标一体化评价技术,主要对盆地、含油气系统、区带、圈闭以及勘探开发区块进行资源潜力评价和空间分布预测,并通过地质风险、工程、经济等方面的综合评价和决策分析,对有利目标进行评价和优选,对于提高勘探效率,降低勘探风险,实现油气资源动态管理具有重要意义。通过对该技术在国外研究和应用现状及发展趋势的分析,结合当前我国油气资源评价和勘探目标评价现状,指出了我国油气勘探评价存在着数据库建设滞后、各种评价参数积累不够、参数选择随意性大等问题,认为我国石油公司应坚持“以自主开发为主,适度引进”的思路,发展具有自主知识产权的核心勘探评价技术,以提高油气勘探水平,增强国际竞争力。

Integrated Evaluation Technology of Resources and Targets and Its Implication for Petroleum Exploration

The integrated evaluation technology of resources and targets is mainly used to evaluate resources potential and predict spatial distribution of basins, petroleum systems, zones, traps, exploration and development blocks. Besides, ii is used to evaluate and select favorable targets based on comprehensive evaluation and decision analysis. It is of great significance to improve the efficiency of exploration, reduce exploration risks, and rcalize dynamic management of oil and gas resources. This paper analyzes the research, application, and outlooks of this technology in foreign oil companies. In accordance with the progress of resources evaluation and targets evaluation in China, this paper summarizes the main challenges facing Chinese oil companies, such the backward database construction, inadequate accumulation of evaluating parameters, and random parameters selection, etc. It is believed that Chinese oil companies should develop core exploration and evaluation technologies with independent intellectual property on the basis of independent development and moderate introduction so as to improve oil and gas exploration and strengthen international competitiveness.
