摘　　要：裂缝性生物礁灰岩储层具有内部断层及裂缝发育,底水沿裂缝高速窜井,在油田开发过程中受到高含水的影响,基质中的剩余油较难采出。目前控水颗粒充填裂缝堵水工艺措施应用广泛,在控水颗粒充填过程中,充填压力的确定关系着充填施工的成败并影响油井开发效果。文章通过理论公式方法,并结合现场挤注测试,形成礁灰岩储层裂缝充填压力的预测方法。应用结果表明,预测结果与施工过程中的工程数据基本吻合,为裂缝性礁灰岩储层控水颗粒充填提供了技术支撑。The fractured biohermal limestone reservoir has internal fault and fracture development,and the bottom water is channeled along the fracture at high speed.The remaining oil in the matrix is difficult to recover due to the influence of high water cut in the process of oilfield development.At present,the technology measures of water plugging process in crack of water-controlled particle filling are widely used.In the process of water-controlled particle filling,the determination of filling pressure is related to the success or failure of filling construction and affected the development effect of oil well.In this paper,a method for predicting the filling pressure of reef limestone reservoir fractures is established by means of theoretical formula and field squeeze test.The application results show that the predicted results are basically consistent with the engineering data in the construction process,which provides technical support for water-controlled particle filling in fractured reef limestone reservoirs.
