In the process of oil and gas drilling engineering, measurement of downhole parameters while drilling is very important. Especially for the drilling of multi-branch wells and horizontal wells, the downhole condition is more complex, which leads to the increase of the incidence of drilling accidents. Accidents such as damage of drill tools and sticking often occur in the process of oil drilling. The occurrence of these accidents is closely related to the real-time engineering parameters of drilling. Therefore, real-time monitoring of downhole torque, drill-fluid pressure, rotation rate, annular pressure, vibration and other parameters are of great significance for well drilling and the prevent of accidents. Here we developed a kind of near-bit measurement system for dynamic parameters while drilling, which can measure the torque and weight on bit, pressure of drilling mud, rotational speed and triaxial vibration in real time while drilling. Real-time analysis of the downhole data can be used to evaluate the performance of the downhole tools and prevent drilling accidents. The paper briefly introduced the work principles, composition and application of the system. Also, this paper will highlight the technical development and present helpful case histories and recommendations.
