基于流压的缝洞型油藏能量评价研究

The Energy Evaluation Research of Fracture-Vuggy Reservoir Based on the Analysis of Flow Pressure

以流压资料为基础,根据物质平衡原理及其变形,研究了不同储集类型单元驱动能量转换及变化特征,为制定开发政策提供依据。研究表明,流压与静压具有相同或相似的变化趋势,流压资料能更直观体现驱动能量的转换;根据Dpr-Npr相关性,建立了适合塔河油田不同类型单元能量评价模版与指标界限标准;明确了不同类型单元能量变化特征,为相似单元开发提供参考。

Based on the data of flowing pressure,according to the principle of material balance and its variant,we studied the drive energy change and variation characteristics in different reservoir types of units to provide the basis for development policy. Studies have shown that flow pressure and hydrostatic pressure are the same or similar trends,and flow pressure can provide better performance in driven energy conversion. According to the Dpr-Npr correlation,Tahe oilfield has established different types of units energy evaluation template and index boundary criteria,which defines the different types of units of energy variation characteristics and can provide reference for similar unit development.
