Description
Technical Field

Petroleum is an important energy source, and as petroleum exploration continues to go deep, the stratum structure is more and more complex. In the drilling process, the application of downhole drilling engineering parameters has important engineering value for downhole fault diagnosis, stratum analysis, safety prediction and evaluation and basic research of drilling technology. Therefore, in order to effectively prevent underground engineering accidents, the drilling efficiency and economic benefit are improved, and the requirements on measurement instruments while drilling in the drilling process are higher and higher.
Daily drilling dynamic measurements rely on measurement while drilling tools to acquire data, which only provide data of the position of the measurement while drilling tool at the bottom hole assembly, but not of the drill bit for downhole operations, and the measurement position is at a distance from the drill bit, and vibration signals at the drill bit position can be severely attenuated, resulting in missing or invalid recorded data.
With the increase of well depth, the occurrence rate of drilling accidents and complex faults is higher and higher, drilling accidents such as stuck drilling, tooth falling and the like can occur to different degrees, and the occurrence of the accidents is closely related to engineering parameters at the position close to a drill bit. Meanwhile, with the development of downhole measuring tools, near-bit engineering parameters are becoming aware that the near-bit engineering parameters contain a great deal of information that reflects the most effective downhole bit operation.
The design of the near-bit measurement tool is therefore better suited for a clearer understanding of downhole dynamics. In particular, the closer the measuring point is to the drill bit, the better, and in order to obtain an accurate drill bit movement state, the measuring tool needs to be as close to the drill bit as possible. However, at present, the domestic measuring tool mainly comprises a drill collar, the measuring tool is arranged on the drill collar and far away from the drill bit, and meanwhile, the length of a near-bit pup joint which is arranged above the drill bit and positioned below a drill rod cannot be overlong due to the restriction of the dogleg degree during drilling.
