B239超前注水建立有效驱替压力系统研究
Researches on Building Effective Displacement Pressure System of Advanced Water Injection in B239 Well-Block Reservoir
摘要
Abstract
The Chang 6 ultra-low permeability reservoirs test block of well-block B239 is developed with advanced water injec-tion. However,the development effect has not reached expectations as planned. For this reason,we carryied out the research on the effectiveness of advanced water injection on improving development results. Based on the pattern of the infill wells adjustment,we designed the research plan by combining reservoir engineering and numerical simulation method. Researches show that the advanced water injection is more effective if the well spacing of the well network system reaches the effective distance. If the well spacing is too wide,advanced water injection cannot work or the effect is little. In that case high pressure will only appear at the bottom hole,without effective displacement. This study provides theoretical basis and technical support to advanced water injection development in other low permeability and ultra-low permeability oilfields,which has an important guiding significance for the exploitation of such oilfields.关键词
