RFT评价储层渗透性能

The Study of RFT in the Evaluation of Reservoir Permeability

本文采用压力恢复法球状模型，从理论上得到重复式电缆地层测试器（ＲＦＴ）渗透率评价公式，并结合塔里木盆地轮南油田实际资料，对油藏开发过程中的渗透性能进行综合评价，从而扩展了ＲＦＴ的应用范围。

The formula of evaluating the permeability of Repeat Formation Tester can be gained theoretically by using the spherical model of pressure resumption. With the actual data from Lunan oil field of Tarim Basin, the characteristics of permeation during oil reservoir exploitation are comprehensively evaluated. As the result, the application of RFT has expanded.
