“勘探程度”的思考
|
摘要
勘探程度的传统内涵是对一个探区地震、钻井等实物工作量投入以及资源探明程度的表征。勘探程度的高低是划分勘探阶段的重要依据,但并不总是能够准确地表征一个探区的勘探潜力。勘探实践表明,勘探程度相对较高的老区富油气区带同样时常取得勘探的突破,而这些油气的发现往往与认识的突破有关。鉴于此,提出勘探程度的完整概念表达应该是传统意义上的工作量实施程度加上认识程度,而且认识程度是勘探程度的核心内涵,是决定勘探发现的关键。这一概念的提出有助于对所谓勘探中、晚期探区的勘探思想的进一步解放,有助于对传统意义上勘探程度很高的老区富油气区带,通过深化认识程度,从而实现油气勘探的新突破。
The traditional connotation of the degree of exploration is a token of the seismic and drilling workload and proven degree of resources in an exploratory area. High and low degree of exploration is an important basis for dividing the exploration phase, but it is not always an accurate token of the exploration potential of an exploratory area. Practice shows that breakthroughs in exploration are often made in the old rich oil and gas areas with higher degree of exploration, these findings of oil and gas are frequently associated with the breakthrough in recognition. In view of this, a complete concept of exploration degree should be the traditional sense of workload plus the degree of recognition, furthermore the degree of recognition is the core connotation of exploration degree and it determines exploration and discovery. The proposal of the concept may be conducive to the further emancipation of thinking on the exploration of so-called exploratory areas in middle and late exploration stages. It may also be useful to achieve new breakthroughs in exploration for oil and gas in the old rich oil and gas areas with traditionally higher exploration degree, based on deepening recognition.
