油管传输电子压力计在注汽评价中的应用

Application of Tubing Conveyed Electric Gauge to Steam Injection Evaluation

哈萨克斯坦某稠油油田×井在注蒸汽测量高温五参数中途遇阻后,为了解地层吸汽情况,焖井后期采用油管传输电子压力计的方式测量了井筒压力和温度。电子压力计数据处理的关键是时深转换。根据油管作业记录结合实测压力响应得到了准确的时深关系,进而绘制了井温剖面。结果表明,油管传输电子压力计取得的数据可用于定性、半定量分析地层吸汽情况,对于汽窜的识别也很有效。

×well is located in a viscous oil oilfield in Kazakhstan, after steam injection the high- temperature logging tool with five parameters was run in hole but got sticked halfway. In order to get information about the steam entry, tubing conveyed electronic gauge was run in the hole to measure the wellbore pressure and temperature in late soak stage. The key point of data processing is time-depth conversion. According to operation records and the measured pressure response, an accurate time-depth relationship was obtained, and then the well temperature profile was plotted. The result indicates that the data measured by tubing conveyed electronic gauge can be used to make qualitative and semi-quantitative analysis of the formation steam injection, so recognition of steam channeling is also very effective.
