示踪剂在砂砾岩油藏开发中的应用

微量物质示踪测试的工作程序简单易行,不受油层埋深、储集层性质及流体性质限制。克拉玛依油田五，东上乌尔禾组复杂砂砾岩油藏进行的4个井组的示踪剂测试结果与生产实际相吻合;解释确定的复杂砂砾岩油藏渗流特征及断层性质封闭,对现场实际注采工作提供了明确的指导,对确定今后开发调整提供了可靠的依据。这项技术可广泛应用于砂砾岩油藏的开发中。

Application of Micromatter Trace Test to Glutenite Reservoirs

In early stage of glutenite reservoir development, it is hard by using conventional dynamic monitoring data to interpret and grasp such issues as direction of reservoir heterogeneity, flowing regularity and availability of injected water, existence of high permeability zone, effect of fault on water injection, well response, residual oil saturation in high-capacity channels, etc. For these reasons, the micromatter trace tester was introduced in 2002 for its simple and feasible procedure and being independent of reservoir depth, reservoir quality and fluid property. The tracer test has been run in four well groups of complex glutenite reservoirs of Upper Wuerhe formation of East District 5-(3) in Karamay oilfield, and the results are in accordance with the actual situation. The interpreted and ascertained percolation and sealing fault in the reservoirs can be as a guide for field injection-production efforts and as a solid basis for further development and adjustment.
