Description

Technical Field

[0001] The invention belongs to the field of mechanical equipment for engineering or geological drilling, and relates to a flexible wheel-type orifice device and method for measuring multiple drilling parameters. Background Art

[0002] In geological or engineering drilling, drill bits need to transmit torque and drilling fluid, and are important devices for completing drilling operations. Drilling parameters are an important guarantee for monitoring the construction status of drill bits, and continuous, stable and rapid transmission and communication of data signals are key issues.

[0003] At present, the measurement of drilling parameters is mainly achieved through the measurement while drilling system. The products are mainly divided into wireless and wired. The wired measurement while drilling device is equipped with a communication cable. The signal transmission must rely on a special cable drill pipe instead of a conventional drill pipe, which is not very versatile. The wireless measurement while drilling device solves this problem, but the cost also increases. Signal transmission is one of the key technologies of measurement while drilling. The signal transmission of the wireless measurement while drilling system mainly includes electromagnetic waves and mud pulses. When electromagnetic waves are transmitted in the formation, the signal is severely attenuated and can only be sent at a lower frequency. Therefore, it is not widely used; using mud pulses for information transmission has better reliability and can be transmitted over long distances. However, in actual engineering applications, mud pulse signals need to solve two major problems during transmission: signal interference and signal attenuation. Summary of the invention

The drill is also subjected to the reaction force from each spring 204 to resist deformation. The well depth wheel 212 and angle wheel 311 are both made of flame-retardant rubber to dissipate and absorb the vibration impact of multiple directions coupled from the drill under different working conditions, ensuring the stability of the drilling equipment operation. When multiple sections of drill are installed in parallel, the structure similar to a cantilever beam is prone to flexible deformation, and the device plays a role in flexible straightening support for the drill.

The number of circles measured by multiple sets of encoders are N1, N2...N respectively. j , j is the number of angle wheel assemblies, and the average value of the number of j sets of encoding circles is recorded as After eliminating the wild points with an average error of more than 5%, the average value of the reasonable data is calculated again, which is recorded as The rotation speed of the angle wheel is The radius of the angle wheel is r2, the radius of the drill is R, and the speed of the drill is Unit: r / min; Set the number of turns of the angle wheel The decimal part of is x, then the tool face angle of the drill is
