Description
Technical field
The present invention relates to field of oil drilling, and in particular to one kind orientation MWD underground probes.
Background technology
The major technique in horizontal well drilling is MWD at present（I.e. with brill deviational survey）, measurement-while-drilling system senses by underground
Device assembly, data transfer or recorded downhole device and ground detection processing equipment form.All While drilling systems are applied and abut drill bit
The sensor on top measures drilling parameter and formation parameter, and the real-time data transmission measured during drilling well leads ground.MWD is general
Hole deviation, orientation and tool-face direction can be measured.And sensor cluster is often arranged in inserting tube in measurement-while-drilling system, inserting tube with
Drill bit moves together, and due to factors such as the vibrations of drill bit, sensor cluster tends to damage, and this just needs one kind can conveniently more
The inserting tube of emat sensor.
The content of the invention
For drawbacks described above present in prior art and deficiency, the invention provides a kind of oil drilling to orient MWD wells
Lower probing.
The present invention is achieved by the following technical solution：A kind of oil drilling orients MWD underground probes, and its feature exists
In：It includes inserting tube set, the inserting tube seat for being threaded in inserting tube set afterbody and dismountable measurement being arranged on inside inserting tube set
Sensor, the second inserting tube set that described inserting tube set includes the first inserting tube set of open rearward end and is arranged in the first inserting tube set,
Rubber bushing is additionally provided between described the first inserting tube set and the second inserting tube set, is provided with the first described inserting tube set logical
Hole, described measurement sensor are shaft-like, and measurement sensor can stretch out in inserting tube set front portion by through hole, and the front portion of inserting tube set is also
The bearing of measurement sensor can be engaged by being provided with.
Its afterbody of described measurement sensor is taper, and the front portion of described inserting tube seat is in coordinating with Sensor tail
Taper.
Turn is additionally provided between described rubber bushing and the second inserting tube set.
Described measurement sensor is hole deviation angle transducer or azimuth sensor or tool face sensor or rock stratum sensing
Device or its combination.
Described measurement sensor is GR sensor or neutron-sensing device or sonic sensor or its combination.
The present invention is simple and compact for structure, can conveniently change sensor cluster, while the group of different sensors component
Closing application also causes mwd system to have the function of some LWD systems；The cushioning effect of bearing and rubber bushing and turn is bright
It is aobvious, effectively extend the life-span of sensor cluster.
