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 oil well pressure profile was measured several times under different working regimes and time conditions by using the magnetic positioning, pressure and temperature combination logging tool. The average density of the well medium was calculated by the pressure variation. The depth of the oil well and the height of the foam section were determined according to the density value , And the liquid level data measured by the liquid level monitor are used for comparative analysis. The position of the outlet section, the foam section and the oil section are judged according to the change of the density, thereby providing quantitative data for the dynamic analysis of the reservoir.
