| Chang3of Zhuang73Investment in development since2009, plane pressure unevenlydistributed, high proportion of low-yielding wells,production decline fast, local micro-fractures, lead to some wells flooded, the obvious contradiction between layers, uneven waterproblems are gradually exposed, and large local differences.This study in the village73long three reservoirs on the basis of basic geologicalresearch,anatomy reservoir fractures distribution rules and the development of law,understanding of reservoir water flooding the law, effective law see the water, the pressuredistribution and the law of diminishing, identify the main problems that exist in reservoirdevelopment, reservoir engineering through comprehensive research, OK adapt technologypolicy and stable long three reservoirs efficient countermeasure development:Fine injection relationship analysis, improve water efficiency, partition management,adjusting the injection parameters, profile adjustments, Improve water drive extent, improveedge injection patterns, establish an effective driving pressure system to ensure long-termstable. |
