Influencing Factors For ASP Flooding Development Effectiveness In ShuangHe Oilfield

On the basis of the water flooding numerical simulation model of Shuanghe Oilfield,according to the indoor test results of the ASP displacement system,the numerical simulation model of the block is established.And then,the tracking history match of the model is done based on the dynamic development data.According to the history match process,analysis the producing well development effectiveness,and then calculate the remaining oil reserves under different abundance.According the accurate history matching result,determine the development effect influence by the single component and interaction of different component,and then optimize the formulation of each plug of the ASP drive.Using numerical simulation method,according to the specific situation of the objective area and to drive for the influence of system parameters,injection production parameters on the development effect are analyzed,conclude the affect degree of each parameter on the development effect,and the parameters for the optimal range of this area.In addition,on ternary combination flooding each interaction between the drive for the influence of system physicochemical characteristics and exploitation effect are analyzed and according to the specific circumstances of the objective area,suitable for the optimal concentration range in the area of each branch.Finally,the analysis of asp flooding mine dynamic regularity and index variation characteristics,aim at problems in different geological characteristics in the process of development,establish the typical mechanism model to study the effiction of Layered water injection,Layered proration,profile control,Water plugging and hydraulic fracturing in resolving the problems of edge water encroachment,fluid channeling,Insufficient for liquid in updip area,guide the scene to carry out the dynamic adjustment measures,strengthen the development effect of ASP flooding,maximizing reservoir recovery efficiency.
