Description

technical field [0001] The invention relates to the field of environmental force measurement, in particular to a high-dynamic environmental force measurement device adapted to a moving carrier under high-speed, high-rotation, and high-impact conditions. Background technique [0002] High dynamic carrier mainly refers to high speed (more than 100 rpm and less than 500 rpm in the axial direction, less than 10 rpm in the transverse direction), high speed (more than Mach 2 and less than Mach 5 in the axial direction, and less than Mach 5 in the axial direction) 1 Mach), moving objects under high impact (axial and transverse overloads are both greater than 10000g and less than 30000g, impact time less than 30 milliseconds), especially for mining and rescue, oil drilling, deep well measurement, geological exploration Drilling mechanisms used in other occasions, as well as guided projectiles and conventional ammunition ballistics in the military field. [0003] In the exploration ...

AI Technical Summary

Problems solved by technology

[0003] In the exploration and development of oil and gas fields, the problem of obtaining the environmental information of drilling pipes has always been the main problem and technology that needs to be solved in the drilling construction of deep oil and gas reservoirs, which seriously restricts the development of drilling technology.

[0005] Existing environmental force measurement devices only measure under low dynamic conditions, and their general speed is up to 100 rpm, and their impact is very low. They can only be regarded as a type of inertial measurement unit and cannot be used in high dynamic situations. , such as the high dynamic carrier environment force measuring instrument developed by Beijing Key Laboratory of High Dynamic Navigation Technology
