Abstract:
A system of near-bit measurement while drilling system includes motor system, measurement transmission system, wireless receiving system and non-magnetic short sub. The measurement transmission system is set inside the motor system, and the transmitting device from the measurement transmission system and the receiving device from the wireless receiving system are set inside the non-magnetic cavity. In the process of drilling via drill bit, the azimuth gamma and the well deviation parameters on the formation where the drill bit is located is able to be measured in real time more accurately and then will make real-time wireless transmission toward the wireless receiving system. Compared with conventional measurement while drilling work, the measurement location of the near-bit measurement while drilling system is nearer to the drill bit with non-hysteretic description of well trajectory and formation gamma measurement so as to enhance the drilling-encounter ratio significantly.

Claim (Index 9):
The near-bit measurement while drilling system according to  claim 1 , wherein the safety anti-drop assembly is set between the motor system and the non-magnetic sub, comprising a safety anti-drop sub and a safety anti-drop cap; wherein a through-hole in the center of the safety anti-drop cap with axial penetration is set at and fixed with the upper position of the internal rotation part of the motor system; wherein the transmitting device of the measurement transmission system penetrates the through-hole in the center of the safety anti-drop cap and extends into the non-magnetic safety anti-drop cavity; wherein the lower position of the safety anti-drop sub is connected with the external housing of the motor system, and the upper position is connected with the non-magnetic short sub; wherein the limit shoulder is set at the inner wall of the lower position of the safety anti-drop sub; and wherein the flange is set at the outer wall of the upper position of the safety anti-drop cap and is used to catch the inner part of motor system at the limit shoulder in case of the fracture of lower part of housing.
