Strategies of High Profitable Development for Low Beneficial Gas Reservoirs in Shandong Province

摘要

Low beneficial shallow gas reservoir is one of the important resources for Shandong Province. Technologies of high profitable development for low beneficial gas reservoirs are launched through integrated reservoir managements during various development stages. Progressive exploration and development is put in practice during initial phase, based upon gas reservoir characterization and made gas reservoir engineering research as major measure to enhance drilling success ratio. When entering production mid-stage, performance analysis should be strengthened, and development adjustment should be conducted timely based on available data so as to extend stable production period. And that in the course of late period , management of gas wells should be classified, and fine reservoir characterization is carried into effect fully utilizing geological and performance data, regarding research of distribution rules of remaining gas as breakthrough point. During production, all-process gas formation protection is paid much attention to all the time, and an overall set of technological production measures are explored targeting high gas well de-liverability. The application of integrated reservoir management has effectively improved ultimate recovery factor of the reservoir, as well as development benefit. And it could provide guidance for other type of gas reservoir at the same time.
