Abstract:

The contradiction between improving gas field production rate and controlling formation sand production has become the one of the main problems which restain the gas field exploitation in loose sandstone.To gas well testing and exploiting,it is of important significance that the critical production pressure difference of gas formation sand production is precisely predicted,which is taken as the one of important factors of gas well allocation.The mechanism of sand production in loose sandstone gas field is analyzed in detail,well logging data is used to calculate lithologic mechanics parameters,and also,MohrCoulomb destroyment criterion is used to calculate critical production pressure diffrence of gas well sand production.By comparing the productional sand production pressure diffrence of several wells in S gas field with the calculated critical sand production pressure diffrence,it is found that there is a quite promise coinsidence,which suggests that the method is reasonable and is meaningful for determing reasonable production pressure difference in loose sandstone gas field.

Key words: loose sandstone, gas formation sand production, critical production pressure difference, well logging curve, method application
