摘　　要：柴窑区块为下寺湾油田主力开发区块,属于低孔隙低渗透油藏,在开发初期表现无自然产能、自然递减快、后期低产、含水率高等特征。从2012年注水开发以来通过不断对该区块注水开发效果分析评价,总结出合理有效开发措施,为以后注水稳产开发工作做好调整及改进。Chaiyao block as main development block in Xiasiwan oilfield, belongs to low porosity and low permeability reservoir. At the beginning of development, it showed the characteristics of no natural productivity, quick natural decline, low late yield, higher water content and so on. Since development of water injection in 2010, analysis and evaluation of water injection effect of the block has been carried out, and the reasonable and effective development measures have been summarized.
