Abstract

Abstract:

Sealing ability of cap rock in large and medium gas fields mainly depends on the thickness of cap rock,displacement pressure,interior energy of gas reservoir(pressure coefficient)and gas property(flowing viscosity).Cap rock sealing index(CSI)of gas reservoir is directly proportional to gas accumulation efficiency.The accumulation efficiency of China's large and medium gas fields can be classified into three categories:(1)High efficiency gas reservoirs have accumulation efficiency of over 100?10⁶ m³/(km²·Ma).They are mainly distributed in Tarim,Qaidam,Yinggehai-Qiongzhou,Bohai Bay and Songliao basins,of which Tarim,Qaidam and Yinggehai-Qiongzhou basins are in the majority.(2)Moderate efficiency gas reservoirs have accumulation efficiency in the range of 10?10⁶-100?10⁶ m³/(km²·Ma).They are mainly distributed in Sichuan,East China Sea,Songliao,Bohai Bay,Tarim and Turpan-Hami basins,and most of them are in Sichuan basin.(3)Low efficiency gas reservoirs have accumulation efficiency of lower than 10?10⁶ m³/(km²·Ma).They are mainly distributed in Ordos and Sichuan basins.For the formation of large and medium gas fields in China,the CSI value of cap rocks should be over 10⁹m/s.For gas fields with relatively higher accumulation efficiency,however,the CSI value of cap rocks should be raised even higher.

Key words: cap rock, sealing ability, comprehensive evaluation, index, accumulation efficiency, large and medium gas fields
