| 中文摘要:通过统计我国63个大中型气田天然气输导通道类型得到,断裂输导是我国大中型气田天然气运移的主要通道.通过定义和求取断裂输导天然气能力综合评价参数,对我国46个大中型气田断裂输导天然气能力进行了综合评价,并据断裂输导天然气能力强弱将它们划分为输导能力强、中等和弱三个等级.通过定义和求取大中型气田天然气聚集效率,对我国46个大中型气田天然气聚集效率进行了研究,并据天然气聚集效率的高低将它们划分为高效、中效和低效3个等级.通过断裂输导天然气能力综合评价参数与盆地类型和天然气聚集效率之间关系研究,得到盆地类型不同,大中型气田断裂输导天然气能力不同.天然气聚集效率不同,所需要的断裂输导天然气能力也不同. |

| Abstract:Based on statistics of gas-transporting pathway types of 63 large and medium gas fields in China,the authors consider that fault-transportation seems to be the main gas pathway in large and medium gas fields of China.Through defining and calculating the comprehensive evaluation parameters for gas-transporting capacities through faults,this paper evaluated the gas-transporting capacities though faults of 46 large and medium gas fields in China.They were divided into three degrees,i.e.,strong,middle and weak.By defining and calculating gas accumulation efficiencies of large and medium gas fields,this paper studied the gas accumulation efficiencies of 46 large and medium gas fields in China.They were divided into three degrees,namely,high,middle and low.Based on an investigation of the relationship between the comprehensive evaluation parameters for gas-transporting capacities through faults and gas-accumulation efficiencies of large and medium gas fields,it is considered that different types of basins decide different gas-transporting capacities through faults of large and medium gas fields.Different gas-accumulation efficiencies require different gas-transporting capacities through faults. |
