Abstract: The annulus pressure while drilling (PWD) system may provide real-time annulus pressure data to improve management of downhole pressure, prevent downhole complexities and increase drilling efficiency. The DRPWD system developed independently by CNPC Drilling Research Institute can provide real-time annulus pressure data, temperature, natural gamma and directional parameters at the time of drilling. The data is real-time conveyed to the surface in the form of mud pulse, providing engineers with the decision-making data. With two size specifications, this system has been tested for nearly 20 wells, achieving good application results. It has a broad application prospect for pressure-managing drilling and under-balance drilling services.
