Problems solved by technology
[0002] In the field of oil drilling and production, directional wells and horizontal wells are important technologies for improving oil recovery and stabilizing oilfield production, especially for complex oil and gas layers. The drilling encounter rate and well trajectory control have always restricted the reduction of drilling and production costs. The formation information data collected by accurate measurement-while-drilling instruments plays a decisive role in improving the drilling encounter rate and controlling the wellbore trajectory. It is the guarantee for the success of a well drilling. Calibrate and test various parameters by simulating downhole movement on the ground to ensure that the wellbore trajectory meets the design requirements. At present, the existing downhole measurement while drilling instruments are complex in structure, expensive in cost and high in maintenance cost
