规模序列法在已开发油气聚集带资源评价中的应用——以东营凹陷中央隆起带为例

Application of scope sequence method to resource evaluation of developed oil-gas accumulation zones-taking central uplift belt, Dongying sag as an example. PGRE,

介绍了油气藏资源评价的规模序列法原理。采用规模序列法,分层系、分油藏类型预测分析了具有代表性的已开发油气聚集带(东营凹陷中央隆起带)的资源量以及剩余资源量。与以往资源评价相比,从评价石油资源量向评价高成熟区带剩余可探明储量以及预测剩余资源量的层系、类型方向发展,可以更好地指导勘探。通过对已开发油气聚集带最终探明储量的预测,结合其资源量的评价结果,可以比较准确地计算出资源转换率,用以预测相类似的构造单元的勘探潜力。

The principle of scope sequence method on oil -gas resource evaluation is introduced. The resources quantity and remaining resources quantity in representative developed oil -gas accumulation zone ( central uplift belt, Donying sag) are estimated and analyzed by series of strata and hydrocarbon reservoir types using this method. Compared with the former resource evaluation, it is developed from petroleum resource quality evaluation to remaining possible proven reserves evaluation in high -mature province and remaining resource quality prediction by series of strata and type. It can guide exploration better. Through the ultimate proven reserves forecast for the developed oil -gas accumulation zones and the estimated result of resource quality, the resources conversion rate can be calculated accurately, and it can predict the exploration potential of the analo- gous structural units.
