Kanzawa pointed, the abdominal vertebra BMD of PTH gene individuals in BB genetype is obviously higher than those of Bb and bb genetype,so he considered that the BstBI polymorphism of PTH gene has dependability with BMD while the DraⅡpolymorphism of PTH gene has no dependablity with BMD.3 The polymorphism of estrogen receptor gene and postmenopausal osteoporosisPMOP is a metabolic bone disease existing in post-menopause femmes, as a result of these femmes\' hypofunction of ovary,ESG level drawdown and the disequilibrium of bone couple procedure,the bone resorption of osteoclast exceeds the bone formation of osteoblastic,osteopenia and bone fragility accrescence have developed,then induces fracture and so on.

It is to divide the flow units, and then calculate the single well controlled reserves regarding the flow unit as the calculating unit, finally, compare and analyze the results from this method, single well controlled area method and dynamic pressure drawdown method respectively. The comparison result proves the scientificity and practicability of the flow unit method.

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.
