摘　　要：文章介绍了多分层试井仪的压力测试原理以及压力测试模型,并对压力下降法和压力恢复法求地层渗透率等参数进行了分析比较。建立了柱形压力恢复法和球形压力恢复法的数学模型,为提高多分层试井仪的测试精度提供了理论参考。Based on the pressure data analysis and the data measuring, this paper explains the pressure buildup and pressure formation testing of MSWT Compares the means of pressure drawdown and pressure buildup in calculated the permeability of formation, establishesd mathematical models for cylindrical pressure buildup and orbicular pressure buildup, and provids the theoretical basement for the reason of rising the precision of MSWT.
