In view of practical problem during Sulige gas field development, this paper complete follow study content. Study material balance theory of two district compound gas reservoir. Carry out stress sensitivity experiment on matrix rock and labor created fracture core from Sulige gas field with America Core Company high pressure high temperature flow experimental instrument to study stress sensitivity change rule of different permeability matrix rock and created fracture core at the condition of time and again switch on and off well and different drawdown pressure. Carry out depletion experiment on matrix rock of different permeability serial combination with different kinds of allocation, using double core clamper serial connected experimental apparatus, to study gas well production performance of bi-zonal compound low permeability reservoir during low pressure production stage. At the basis of experimental study, establish single well simulation model to analyze development index infection caused by stress sensibility and production performance infection rule caused by inner formation and outer formation of bi-zonal compound gas reservoir permeability variation while considering stress sensitivity.

Their parties abroad were less varied than before; and at home she had a mother and sister whose constant repinings at the dulness of every thing around them threw a real gloom over their domestic circle; and, though Kitty might in time regain her natural degree of sense, since the disturbers of her brain were removed, her other sister, from whose disposition greater evil might be apprehended, was likely to be hardened in all her folly and assurance by a situation of such double danger as a watering place and a camp. Upon the whole, therefore, she found what has been sometimes found before, that an event to which she had looked forward with impatient desire, did not, in taking place, bring all the satisfaction she had promised herself.
