油气在生排运聚成藏过程中须经历生烃、排烃、运烃、聚烃和资源等 5个门限。某一确定的油气运聚成藏系统进入任一个门限都将损耗一部分烃量。在实际地质条件下 ,源岩生成的烃量只有超过进入各个门限时损耗烃量之和才能大规模聚集成藏 ,并构成油气勘探的远景区。根据物质平衡原理研究油气生成量和损耗量之间的平衡关系 ,建立了相应的地质模型。在此基础上 ,提出了门限控烃作用及其计算模型。文中阐明了各门限的地质含义、判别标准及其控油气作用机理 ,给出了应用实例
Hydrocarbons should undergo five thresholds of hydrocarbon generation, hydrocarbon expulsion, hydrocarbon transport, poly-olefins and resources in the process of raw drainage and accumulation. A certain amount of hydrocarbons will be lost if any certain hydrocarbon accumulation system enters any threshold. Under actual geological conditions, the amount of hydrocarbon generated by the source rocks only aggregates into large amounts and accumulates until the sum of the amount of depleted hydrocarbons reaches each threshold, and constitutes a prospective area for oil and gas exploration. According to the principle of material balance, the paper studies the equilibrium relationship between oil and gas production and loss, and establishes the corresponding geological model. On this basis, the threshold control of hydrocarbon and its calculation model are proposed. In this paper, the geological meaning of each threshold, criterion and the action mechanism of oil and gas are explained, and the application examples
