The Reconstruction Method On Ultrahigh Water Cut Stage On Sapugao Reservoir Well Network Layer System

Sazhong development area after49years of development has entered the development ofthe high water cut stage.Various types of reservoir enhanced oil recovery has beennoticed;good perforations in high water cut stage SaPuGao reservoir reserves, the thickness ofthe use of and potential restructuring development Department reconstruction of the wellnetwork model, developed on Sa District to optimize the long-term planning to promotesecondary development of reservoir research, to improve oil recovery and development of theoverall effectiveness to ensure that the oil field continued stable production, create greenharmony "century Oilfield significance.According to the theory of reservoir engineering, fine reservoir geological description ofthe outcome of perforations in various types of reservoir development status, the distributionof reserves, the remaining oil characteristics, to investigate the status of the development ofdifferent sets of SaPuGao types of reservoir well network, sub-blocks demonstrated varioustypes of reservoir wells network development model, through the perforations in Sa Pusophomore, three types of reservoir potential understanding of the the Sa Pu sophomore,reorganization of the three types of oil layers Department, well reconstruction, and formed aSa Pu area varies sophomore, the personality of the three types of reservoir tertiary oilrecovery well network deployment and exploitation of the way. Deduce two three types ofreservoirs and Gaotaizi reservoirs wells net three times, and argues the combination ofdifferent sets of well water network polymer flooding stage strata. Sought by studying thevarious types of reservoir potential of Sa Pu Sa in the field, explore the deployment of acombination of various types of reservoir strata in the secondary development and wellnetwork, the secondary development of the perforations in the provision of technical support,improved oilfield the development of the overall effectiveness.Promote the use of article research can be carried out in Sazhong Development Area andDaqing Changyuan oil production plant, with broad application prospects, and achieved goodeconomic and social benefits.
