应用油气藏规模序列法预测金湖凹陷的油气资源

成熟探区未发现油气资源量的规模备受关注。根据金湖凹陷的油气藏规模序列,应用 Pareto 定律估计该区的油气地质资源总量为 10 802×104 t, 分布于 159 个油藏中; 未发现油气地质资源量为 4 038×104 t, 分布于 58 个油藏中。这反映了该区的油气勘探程度较高,但仍有一定的勘探潜力,大量中小油气藏是今后勘探的主攻目标。油气藏规模序列法预测油气资源,计算过程简单,具有广阔的应用前景。

Application of Pool Size Sequence Method to Prediction of Petroleum Resources in Jinhu Sag

The scale of oil-gas resources undiscovered in mature hydrocarbon province is greatly paid attention to.This paper presents a pool size sequence method and estimates the remaining petroleum resources in Jinhu sag with the total amount of the resources of 10 802×104 t and their distribution in nearly 159 reservoirs, of which the undiscovered resources amount to 4 038×104 t, distributing in about 58 reservoirs.Although it has a higher extent of exploration in this area, there still exist some potential for petroleum prospecting.A great number of medium-small-sized pools will be as key targets for further exploration in the future.The pool size sequence method can be applied to make a prediction of the petroleum resources by way of simple procedure, and is of a broad application prospect.
