【Abstract】 Based on studying deeply the permeation los ing mechanism of oil or gas through a fault and its influence factors, the influence of strata denudation to the permeation losing of oil or gas through a fault is analyzed, and the geological and mathemati cal models for the influence of strata denudation to the permeation losing of oil or gas through a fault is established. The modeling calculation results indi cated that strata denudation maks the permeation losing amount of oil through a fault to increaes, the permeation losing amount of gas through a fault to decrease. The results tally with the change of factors influencing the permeation losing amount of oil or gas through a fault vs. depth.更多还原
