孔店—灯明寺探区油气资源结构及勘探效益预测

孔店—灯明寺探区位于黄骅坳陷南部,油气资源丰富,但随着勘探程度的提高,勘探难度越来越大。这就要求勘探者不仅要明确剩余资源潜力,而且要对剩余油气藏的规模结构及勘探效益有比较清晰的认识。本文应用发现过程抽样分析模型对该区剩余油气藏规模结构进行了预测,在此基础上,通过仿真模拟实现了探区勘探效益的预测。预测结果表明,孔店—灯明寺探区大部分剩余石油资源分布于中、小规模油藏中;未来20年,累计探明储量仍呈稳定增长趋势,但勘探效益将缓慢递减。

PREDICTION OF OIL-GAS RESOURCE STRUCTURE AND EXPLORATION BENEFIT IN KONGDIAN-DENGMINGSI EXPLORATION REGION

Kongdian-Dengmingsi exploration region is a petroleum accumulation system in the south of Huanghua depression.With the enhancing of exploration degree,remaining reserves discovery becomes more and more difficult.To guide the exploration better,it is urgent to evaluate and predict not only the distribution of oil pools but also the exploration benefit.The sampling analysis discovery process model was used in this paper.Based on the evaluation results,the undiscovered oil resource is mainly distributed in the middle and little sized pools,and the exploration benefit in the next 20 years will take on a slowly descending trend.
