Abstract
A data logger and a data acquisition hydraulic fracturing process. In a state in which a bridge plug is fixed in a wellbore, both ends of the bridge plug are monitored and data is stored by the data logger, then the data logger is retrieved to analyze the data to evaluate plugging effect of the bridge plug and downhole environment status.
Claims8
A data acquisition hydraulic fracturing process, comprising the following steps:
- S1, putting a bridge plug into a wellbore, the bridge plug being a soluble bridge plug;
- S2, fixing the bridge plug at a predetermined position;
- S3, putting a data logger into the wellbore, the data logger passing through a bridge plug hole of the bridge plug;
- S4, putting a bridge plug ball into the wellbore and introducing a fracturing fluid into the wellbore;
- S5, monitoring a peripheral environment in real time by the data logger and storing the monitored data;
- S6, introducing a drilling fluid into the wellbore after the bridge plug is slowly dissolved to retrieve the data logger;
- and
- S7, obtaining the data in the data logger for analysis.
