AN ASSESSMENT SIMULATION SYSTEM OF NATURAL GAS RESOURCES
-
摘要: 本文根据含油气盆地油气成藏与分布的特点,提出了一个既适用于孔隙性气藏又适用于裂缝性气藏的“天然气资源评价模拟系统”。它是一个建立在超母体概念和对数正态分布概率体制上,以勘探层为评价单位,以局部构造为预测基础的新方法。在评价过程中,系统将勘探实践资料、地质学家的经验和预测模式结合成一个反馈机制,通过地质与统计模型间的相互校验和匹配来研究预测过程,并由此估算评价区的天然气资源量、潜量和气藏个数,最后进行资源评价和勘探决策。Abstract: Based on the characteristics of the formation and distribution of oil/gas pools in petroliferous basin,this paper proposed anassessment simulation system applicable for natural gas resources either attribated to porous or fissure types of gas pools. This new system is developed on the concept of super population and the probability of normal logarithmic dis tribution, taking plays as assessment units and local structures as prediction basis.
