一种新型注入剖面组合测井仪及其应用

A new injection profile combination logging tool and its application

为了提高注入剖面测井的准确性,研制了一种新型注入剖面组合测井仪。该仪器由流量处理单元、伽马处理单元、井温处理单元、磁性定位处理单元、调制式传输、电源电路六部分组成。一次下井可同时测取流量、伽马、井温、磁性定位四组参数。具有测取资料精度高、单芯电缆传输、流量可单点测量也可连续测量以及现场监测和维修方便等特点。

In order to improve the accuracy of water injection profile logging, a new water injection profile logging tool is developed. The tool consists of flowrate processing unit, gamma processing unit, temperature processing unit, magnetic signal processing unit, modulating transmission unit and electric processing Unit. The tool can measure four parameters at the same time, They are flow rate, gamma , temperature and casing collar locator. The design of the tool is put emphasis on the quantity of the logging data, monitors of the spot application, the maintenance and examination of the breakdown. The measuring data's accuracy is high, the data transmits by the single core cable, and the flow rate can be measured by fixed-point way and continuous way.
