纯47断块注入水锥进油藏特征研究

以油藏水锥理论为依据，分析研究厚油层中不同沉积韵律层水锥的基本模式与特征，通过研究分析确定，该断块油水界面是波状起伏的倾斜曲面，其特高含水期同样蕴藏着可观的剩余油潜力，有效地控制该断块注入水锥进是提高剩余油动用程度、改善开发效果的关键。通过实施综合措施，提高了该断块的采收率，对同类油藏进一步改善开发效果、提高采收率与经济效益具有现实的参考作用。

Study on coning of injected water in fault block Chun 47

According to reservoir water coning theory, basic modes and characteristics of water coning in thick reservoirs with different sedimentary rhythm are analyzed and studied. It is determined that the oil - water contacl of fault block Chun 47 is fluctuating and tilted. There may be considerable residual oil even in high water cut period. The key to improving residual oil producing degree and development effect in this block is to control coning of injected water. By using comprehensive measures, the recovery factor and recoverable reserves of this block has been improved. This study is a reference to similar reservoirs for further improving development effect, recovery factor and economic benefit.
