Abstract
A downhole fracturing zone data logger and a downhole fracturing zone data acquisition system. The data logger includes a sphere, at least one mounting cavity is provided on a surface thereof, a data acquisition module for detecting and acquiring environmental data is provided in the mounting cavity, and an opening of the mounting cavity is provided with a soluble plug for plugging. The data acquisition system can effectively monitor downhole temperature and pressure data.
Claims10
A downhole fracturing zone data acquisition system, comprising:
- a soluble bridge plug placed in a downhole channel and snapped in the downhole channel after the bridge plug is expanded, a port of the bridge plug facing an entrance of the downhole channel being a positioning port;
- and
- a data logger comprising a soluble sphere and a data acquisition module for detecting and acquiring environmental data, at least one mounting cavity being provided on the sphere, the data acquisition module being mounted in the mounting cavity, and at least a part of an inner wall of the mounting cavity being close to an outer peripheral wall of the sphere;
- and
- wherein a fracturing fluid is continuously injected while the sphere enters the downhole channel, so that the fracturing fluid can push the sphere to reach the positioning port to plug the port of the bridge plug facing the entrance of the downhole channel, and the data acquisition module works to acquire and save the environmental data in the fracturing zone.
