The Development Program Design And Optimization For M Reservoir In Sulige Gas Field

Gas reservoir development scheme design is very important in the development processof the gas reservoir, In this paper, the target gas reservoir is at the early stage ofdevelopment,so development plan to develop guidance for gas reservoir has the vitalsignificance to open more in the future. According to the basis of reservoir data, particularlystudy the physical property of reservoir and fluid characteristics, and analyzing the system oftemperature and pressure in gas reservoir, this reservoir is a dry gas reservoir with lowpermeability under the normal pressure system which bases on the above factors. In addition,aapplication of petrel geological modeling software and combined with geological knowledgeto set up geological model, according to the result of log interpretation、test data of highpressure physical properties and fluid characteristic to build a model of reservoir properties,thereby, to have a more intuitive understanding of gas reservoir.According to geological static volumetric method is used to calculate geological reservesof gas reservoir、recoverable reserves and reservoir abundance, furthermore comparativeevaluation of reserves,concluded that the gas reservoir belongs to low yield、low abundance、deep gas reservoir、large gas fields. Analyzed the water energy of the gas reservoir bycombing the production dynamic data and applying the method of dynamic curve method andproduction instructions，obtaining the gas reservoir water energy is weak；meanwhile usingthe method of reduced pressure and analysis of gas well pressure dynamic, to determine thepressure of the gas reservoir system, and according to the above informations of gas reservoir,choosing way of depletion development exploitation of gas reservoir. This paper uses the gaswell production forecasting formulas to evaluate the gas well production capacity,respectively given reasonable productivity and well spacing, for the design of thedevelopment plan provides the reliable theory basis. Furthermore, referring to the principlewell spacing, using the numerical simulation method, putting forward many plans underdifferent well spacing and production, in order to obtain reasonable interval length andproduction by comparing with different horizontal interval length and yield, finally, using themethod of economic evaluation optimization scheme which has the best economic benefits.
