| A Comprehensive Evaluation of Gas-transporting Capacity through Faults of Large and Medium Gas Fields in China |
| 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. |
