Adjustment Of The Reservoir Waterflood Development Technology T114 Wellblock C6 Low Penetration

With the rapid growth of global oil demand, oil and gas exploration and development objects become increasingly complex, the grades of the reserves is getting worse, low and ultra-low permeability reservoir will become the main target of China’s future oil field development. This article is an example to T114well block C6reservoir, the oil field’s production dynamic, the right to establish a quantitative model of the pressure difference between the oil wells production split method and layer a reasonable reflection of the C6to four years of development, the reservoir formed water flood structural differences and structural differences of pressure between the layers. Using a variety of reservoir engineering analysis of reservoir properties differences, pressure differences between layers and water injection strength differences to improve the effect of water flooding of low permeability reservoirs extract.1.by the geological survey of the development of information in T114and find the process of developing problems and contradictions, and the proposed injection well network integrated adjustment system, the use of these methods effectively guide adjustment oilfield comprehensive adjustment, slowing the rate of rise of water cut accelerate the momentum of production decline rate increase, making the oilfield development effectiveness is improved;2.T114well area cut rise features include micro fractures affected by reservoir fractured breakthrough and reservoir heterogeneity controlled porosity breakthrough, mainly in the fractured breakthrough;3. According to the interlayer pressure structural differences mathematical model, bottomhole flowing pressure stratification and production split, found a difference in pressure between layers and each layer dynamic data;4.studied the ability to absorb water injection wells, oil production capacity, the calculated maximum injection pressure wellhead injection wells and the minimum reasonable flow pressure limit;5. studied the critical spacing and single well limit daily fluid production rate;6.presented two adjustment programs.
