采油井液面深度测量准确性评价方法探讨

Evaluation of the Accuracy of Fluid Surface Measurement in the Oil Well

采用磁性定位、压力、温度组合测井仪在不同工作制度及时间条件下多次测量油井压力剖面,通过压力的变化计算井内介质的平均密度,根据密度的数值确定油井液面深度及泡沫段高度,结合液面监测仪测试的液面资料进行对比分析,根据密度的变化值判断出气段、泡沫段及油段的位置,为油藏动态分析提供定量数据。

The paper shows that using CCL,pressure and temperature combination well log instrument measures the pressure profiles of wells in different conditions and repeatedly,then calculates average density of the media in the well from the pressure profile.According to density values determines wells liquid surface depth and the section of bubble.It gives the comparison with the results of the liquid surface monitoring instrument,and the errors analysis of test of the liquid surface monitoring instrument.
