Abstract:
The direct push storage logging technology has been widely used in complex well conditions such as ultra deep, high temperature and high pressure, high inclination wells, and horizontal wells in the Tarim Oilfield. During logging construction, the instrument is combined at the bottom of the drilling tool, and the working status of the instrument needs to be raised to the surface and obtained by reading memory data. The entire logging process is in a "blind logging" state. In order to ensure the timeliness of direct push storage logging, this paper proposes integrating a wireless while drilling measurement system on the upper end of the logging instrument. The instrument measurement signal is uploaded through mud pulses, and the communication status, tension pressure, working voltage, and current of the instrument string are monitored in real time after decoding on the ground. Practical application has shown that this solution effectively solves the problem of "blind logging" in direct push storage logging. During operations, it enables effective determination of whether jamming is caused by drilling tools or logging tools, as well as whether the tool is malfunctioning. This provides data-backed support in real-time decision-making in logging operations and holds value for widespread adoption.
