Abstract
The utility model discloses a wireless electromagnetic wave channel measurement while drilling, which comprises a body wherein a first insulator is installed between a first anti-magnetic drill collar and a second anti-magnetic drill collar, a second insulator is installed between a first signal radiation electrode and a second signal radiation electrode, both the first signal radiation electrode and the anti-magnetic drill collar are electrically connected, the second are the same. Employing wireless transfer way, the utility model not only provides an electromagnetic wave channel with high speed data transmitting, but also is widely applied drillings of mud, air and foam which can not be achieved by the prior drilling techniques of mud pulse and wires.
Description
Technical field
The utility model relates to measurement mechanisms such as a kind of oil drilling, especially relates to a kind of electromagnetic wave channel-type wireless drilling measurement mechanism.
Background technology
In Process of Oil Well Drilling, the data of underground survey are sent on the ground again fast exactly, be the basis that guarantees wellbore quality, improves drilling efficiency.At present, the transmission passage of data has two kinds of mud-pulse formula and cable type.These two kinds of load modes all exist certain shortcoming and limitation.Cable type is eliminated substantially owing to influencing site operation; The mud-pulse formula is to transmit data by the pressure that changes mud, and transfer rate is slower, and (air drilling and foam drilling) then can't be used to some non-mud drilling, has certain limitation.
Summary of the invention
The purpose of this utility model just is to provide a kind of electromagnetic wave channel-type wireless drilling measurement mechanism.
The purpose of this utility model can realize by following measure:
The utility model comprises the measurement mechanism assembly, is provided with second isolator between first signal emitters in the measurement mechanism assembly and the secondary signal emitter stage; Be provided with first isolator between first non magnetic drill collar and second non magnetic drill collar; First signal emitters is connected with first non magnetic drill collar conduction; The secondary signal emitter stage is connected with second non magnetic drill collar conduction.
Secondary signal emitter stage in the utility model in the measurement mechanism assembly is connected with bottomhole assembly by second non magnetic drill collar.First signal emitters in the measurement mechanism assembly is connected to the ground derrick by first non magnetic drill collar and drill string.All there is holding wire to be connected between derrick in the measurement mechanism assembly and the demodulation receiving element, between antenna and the demodulation receiving element and between demodulation receiving element and the data processor.Between first non magnetic drill collar and drilling rod in the measurement mechanism assembly, also be mounted with drill collar between second non magnetic drill collar and the bottomhole assembly.Between first non magnetic drill collar and drilling rod in the measurement mechanism assembly, also be mounted with non magnetic drill collar between second non magnetic drill collar and the bottomhole assembly.Between first non magnetic drill collar and drilling rod in the measurement mechanism assembly, also be mounted with joint between second non magnetic drill collar and the bottomhole assembly.Be equipped with the mud pod apertures on first signal emitters in the measurement mechanism assembly and the secondary signal emitter stage.
The utility model is owing to adopt wireless transmission method, and not only data transfer rate is fast for the electromagnetic wave channel-type like this, and all can use mud drilling, air drilling and foam drilling, is that mud-pulse formula of the prior art and cable type are beyond one's reach.
