利用抽汲压力—温度曲线判断管外窜槽方法与应用

Method of Using Data of Swabbing Pressure-Temperature Curve to Estimate Outside Casing Channeling and Its Application

经对管外窜槽与管外不窜槽资料对比分析,发现地层温度资料在压力资料无法得出正确结论的情况下,地层温度资料起着决定性的作用。利用抽汲期间层内压力—温度曲线与监测压力—温度曲线进行对比分析,可判断下封隔器密封性或地层是否存在管外窜槽。因此,在试油测试过程中,对地层温度资料的分析应引起足够的重视。

Comparing data of outside casing channeling and no channeling, under condition of pressure material having no means of deriving exactness consecutive, formation temperature data plays a decisive role. By using comparison and analysis of internal pressure-temperature curve and monitor pressure-temperature curve during swabbing period, seal situation of packer and whether appearing outside of tubes channeling or not is judged. Therefore, at oil testing process, analysis of formation temperature material should be pay attention to greatly.
