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 1):
A near-bit measurement while drilling system containing motor system, measurement transmission system, wireless receiving system and non-magnetic short sub, wherein the motor system is composed of external housing and internal rotation part; wherein the non-magnetic short sub is set upon the motor system; and wherein the non-magnetic short sub and the motor system are connected directly or through drilling tools or via short sub. The characteristics are: A hole is set inside the internal rotation part of the motor system. The measurement transmission system contains measurement device of data acquisition and data measurement, transmitting device of wireless receiving system to which the data of measurement device is transmitted, transmission device of transmitting device to which the data of measurement device is transmitted, and power supply device for supply electric energy to measurement device and transmitting device. The measurement device and transmission device of the measurement transmission system is set inside the hole of internal rotation part of motor system. The measurement device is set within \u2153 lower position of motor system and within 2 meters from the bottom surface of motor system. The transmitting device of measurement transmission system is set at the upper position of internal rotation part of motor system and extends into non-magnetic cavity. The measurement transmission system is relatively fixed with the rotation part of motor system and is able to rotate along with the external housing of motor system together with the internal rotation part of motor system. The wireless receiving device of wireless receiving system is set inside and relatively fixed with non-magnetic short sub. When the motor system is in operation, the measurement transmission system makes relative rotation upon the wireless receiving system, and the wireless receiving device from the wireless receiving system and the transmitting device from the measurement transmission system will transmit signals through wireless transmission.
