| The low permeability and fractured reservoirs,as the complex reservoirs,are widely distributed in our country,and are the development focus.The technology of detailed reservoir description and the technology of reservoir numerical simulation are the important means of development and exploiting potentialities of the low permeability and fractured reservoirs.And they have important guiding significance to reasonable development of reservoirs,economic and effective exploration potentialities of remaining oil and proposing the next development plan.Adopt the integrating research idea,combine the detailed reservoir description and reservoir numerical simulation,comprehensive research the D165 block from static state to dynamic state and from geology to development.Explore the techniques of developing the low permeability and fractured reservoirs using the technology of detailed reservoir description and the technology of reservoir numerical simulation.In this paper,by using static data,divide the formulation,the stratigraphic division in D165 block is conducted,research the sedimentary characteristics,the reservoir growing characteristics,the sand-body and physical property characteristics.And by using conventional logging data,identify the natural fractures and predict the growing condition of natural fractures in reservoirs.Besides,integrate the results of detailed description into three-dimensional geological modeling software.In the dynamic research,by using the method of reservoir engineering,analysis the development effect,point out the problems during the development process,and evaluate current well pattern and well space.Establish the reservoir numerical simulation model of D165 block,and finish the production history simulation.Finally,research the distribution low of the remaining oil,predict the development of D165 block,propose reasonable well pattern and well space and the next reasonable water injection development policy. |
