Eastern Oil-water Transition Zone In Southern Fuyu Detailed Reservoir Description

Eastern Fuyu oil field development in the southern transition zone reservoir, there are many constraints, mainly: 1) ineffective water flooding. Well irregular because, well perfect, poor well conditions have caused water distribution complex edge, block water flooding is poor, the low degree of control, the remaining potential. Team, particularly in East and East 10 team 4,6. 2) oil-water interface complex. Abnormal development of faults in this area, water distribution is very complex, there is laminated sandwich water gas, the existence of vertical water 2 to 3 sets of systems, each with its own oil-water interface. To the development of great difficulty. 3), yet in-depth understanding of sedimentary reservoir. Effective water work area is poor, despite the 2004-D seismic interpretation was accurate, but block the deposition, reservoir system needs to be thorough, regular fluid migration within the block, the remaining oil distribution is unclear. 4), longitudinal and lateral reservoir heterogeneity serious. Because vertical and horizontal reservoir heterogeneity, so that the process of water flooding, thick layers of serious flooding in parts of high permeability, low permeability and the site has not yet been waves; layer formation of high permeability to water channeling; plane by sedimentary phase bands, easy to form into the phenomenon of water flow. Meanwhile, the block of crude oil with the more complex, especially the highest Fuyu oil viscosity, to a certain extent affected the water effects. 5), comprehensive understanding of the geological reservoir needs to be deepened. Work area fault, a very complex water distribution and development contradictions, but the low level of recovery, has great potential. Deepens the understanding of basic geological reservoir, the premise is to improve development efficiency.Problems for the block, launching the "transition zone in southern Eastern Fuyu reservoir description" field research projects will be established logging database to enhance deposition and reservoir geological knowledge in order to further tap the potential, enhanced oil recovery, extend the field life, improve economic efficiency to provide a reliable basis. Through the structure, sedimentary facies, the spatial distribution of reservoir sand bodies and other research, in the original log data interpretation based on the results, combined with production performance data, analyze the reservoir, to find out the plane and the vertical water distribution, analysis of the The original oil-water distribution area, to provide support for the development of adjustment. Stratigraphic correlation through the study area, faults and micro-structure, sedimentary facies, reservoir distribution and heterogeneity of studies, development of oil fields in the water high water cut, reservoir description of the research results, network deployment and Infill adjusted to address the interlayer and contradictions within the water injection, the remaining oil fields and tapping the potential forecast value of a positive reference.
