The Sebei gas field is featured by multiple layers,loose and sanding production so the production potential of the gas wells was seriously reduced. By taking advantage of dynamic data obtained from well testing,production testing,and historic production data,gas production profile,sand-producing differential pressure,as well as static logging data,a new way of establishing deliverability equation for commingling production is recommended. The new method is convenient for determining the coefficient in the deliverability equation and the absolute open flow potential by combining the theoretical formula with the empirical formula. By combining with MMBS (a performance evaluation software based on the theory of multi-zone material balance),this method can be used for both optimizing proration production and dynamic prediction. Example calculation shows that the result obtained from the newly established proration production optimization method is consistent with that of actual production thus it is significant for gas field production.

Aimed at the difficulty of development and geological research of the bloke 4 of Shuguang Oilfield, Liaohe basin, quantitative sedimentary micofacies research is held according to the sedimentary principle and logging interpretation, the result of stochastic sedimentary microfacies modeling is used to restrict the space distribution of reservoir parameters, and thus it can derive fine geological model, which solve the disfigurement that sedimentary facies research outcome disconnect with reservoir parameter distribution. This method realizes successfully the fine sedimentary micofacies modeling of Dujiatai reservoir of the bloke 4 of Shuguang Oilfield, and provides geological reference to remaining oil research and development adjustment.
