FIELD: measuring equipment.
SUBSTANCE: present invention discloses a measurement system for drilling in the vicinity of a bit, comprising a propulsion system, a measurement and transmission system, wireless reception system and non-magnetic sub, with the specified measurement and transmission system installed inside the motor system and the device sending data specified measurement system and transmission and the receiving device of the wireless receiving system is installed in a non-magnetic internal cavity. In the process of drilling with a chisel, it is possible to more accurately measure in real time the parameters of gamma radiation in the azimuthal direction and the curvature of the well. When the bit stays in the reservoir and transmit them to a real-time wireless reception system via wireless transmission. Compared to conventional measurement procedures in the drilling process, measurements with the indicated measurement system in the process of drilling near the bit are closer to the bit, without lagging the description of the wellbore trajectory and gamma-radiation measurements in the reservoir, and, thus, the rate of penetration increases significantly. Compared with conventional measurement procedures in the process of drilling in the vicinity of the bit, this measurement system in the process of drilling in the vicinity of the bit is better regarding the ability to control the trajectory of the wellbore (the angle of deviation of the straightening of the wellbore) and more accurately describes the geological parameters.
EFFECT: therefore, the rate of penetration increases significantly and there is no lag in describing the well bore trajectory, which reduces the cost of drilling and increases the recovery rate.
