Problems solved by technology
Due to problems such as inclination or tremor of the drill pipe during the drilling process, and too many accidental factors in the internal structure of the formation, the pressure error exerted by the mud or drilling fluid on the pressure acquisition device during the specific operation is too large, and there are many disturbances. There are still errors between the data and the actual situation, which is not conducive to the research and analysis of the stratum by researchers
