辽河坳陷潜山油气资源参数体系研究与评价

Research and Evaluation on Parametric System of Buried Hill Petroleum Resources in Liaohe Depression

辽河坳陷潜山油气资源极为丰富。根据刻度区选择的"三高"原则,选取了勘探程度高、地质认识程度高、资源探明程度高的大民屯潜山等5个地区作为潜山类比刻度区,通过对这些刻度区油气藏的储层、烃源岩、配套史、圈闭、保存等条件进行研究,建立了适合潜山油气资源评价的类比参数体系和取值标准。利用统计法计算了5个潜山刻度区的油气资源量,结合参数体系取值得分,建立了辽河坳陷潜山油气资源类比评价模型。应用该模型,预测出辽河坳陷10个潜山带的资源量,分析了剩余油气资源分布情况,优选出5个有利区带。研究结果对进一步拓宽潜山勘探领域具有一定的指导意义。

The buried hill petroleum resources are very rich in the Liaohe Depression. In this paper,based on the ' three- high' principle of calibratedregion selection,five regions like Damintun buried hill with high exploration maturity,high geologic understanding level and high proved resource degree were selected as the analogy calibrated regions for buried hill. By means of studying the reservoir,source rock,matching history,trap and preservation conditions of oil and gas reservoirs in these calibratedregions,this paper built an analog parameter system and valuing standard suitable for evaluation on the buried hill petroleum resources. Furthermore,this paper used statistical method to predicthydrocarbon resources of the five buried hill calibratedregions,and combined with parametric system and value scoring,built an analog evaluation model of buried hill petroleum resources in the Liaohe Depression. Then,this model was used to predictthe resources of 10 buried hill zones in the Liaohe Depression,analyzed the distribution of remaining petroleum resources,and optimized fivefavorable zones. The study results have some referencesfor further widening the buried hill exploration area.
