Analyzes the in situ pressure testing curve of SFT by means of the straight line simulated. Using the least square method the value for fomation pressure is obtained, the calculation of testing radius based on the stable sepage flow principle is made.

• 分析了SFT现场实测曲线，利用最小二乘法拟合的直线求得了地层压力，并采用稳态渗流原理计算出测试半径，进而应用这些资料分析了油气藏压力，泥浆柱压力以及确定了动用层位和井间连通关系等参数。
