Production Dynamics Analysis And Prediction Of SA Block In X Tight Gas Field

With the increase of energy demand and the decrease of conventional gas reservoir resources,the development of unconventional gas reservoirs is very important.This study targets the X block of tight gas field block SA,currently has the scale of development,but with the further development of the work,well deployment difficulty increased year by year,production increased year by year,how to maintain a stable block,it is urgent to resolve the problem.So,through the study of dynamic single wells on the target area and combine the block dynamic and static data analysis,found the target block can decline infilling through enrichment zone to make up for the block in the production.After that,the research work is done by combining gas production dynamic analysis and numerical simulation.Statistics and Analysis on the dynamic production data block,complete block of the micro structure,sedimentary facies,sand body distribution,and on this basis to establish a block of three-dimensional geological model and combining with production dynamic data,complete numerical simulation research.In the numerical simulation based on the implementation of enrichment area of geological reserves,reserves and remaining reserves distribution of remaining reserves,complete mobility evaluation research work and the contact block remaining reserves and for the optimization of enrichment area preferred area to carry out fine geologic research,determine the main controlling factors of high yield and high yield were analyzed to determine the influence of typical wells the main factors of high yield of gas wells,to carry out the prediction of encryption development index of single well completion,the preferred region reasonable well spacing and the main development index forecast demonstration,proposed and optimization deployment scheme design encryption,encryption evaluation wells recovery,complete encryption well deployment.To carry out the prediction of encryption development index of single well completion,the preferred region reasonable well spacing and the main development index forecast demonstration,put forward and complete optimization encryption deployment scheme design,evaluation of infill area recovery,complete encryption encryption for well deployment after work carried out to provide a basis and reference,but also provide basis for help and the efficient development of SA block.
