Description

Tracer sampling metering device Technical Field The utility model relates to the technical field of sampling and metering devices, in particular to a tracer sampling and metering device. Background In the field of oil exploration and development, tracer technology is widely used as a high-efficiency and accurate tool for monitoring underground fluid dynamics, evaluating reservoir characteristics and optimizing yield-increasing measures. The tracer flows to the production well along with the fluid through the injection well, and key information such as a fluid flow path, a flow speed and the like can be revealed by analyzing the concentration distribution of the tracer in the production well, so that an important basis is provided for oilfield management. However, conventional tracer sampling and metering methods have a number of limitations. Traditionally, the sampling work of tracers has relied mainly on manual operations.
