Abstract
The utility model relates to a wireless drilling measurement gradient meter adopting optical communication. The wireless drilling measurement gradient meter is composed of battery short segments, a centralizer, measurement short segments, and transmission short segments which are connected from the top to the bottom in sequence through thread, the power transmission between the short segments can be realized through outer casing thread at the connector position of each short segment and electric contact posts positioned at the axial center of the connector, and non-contact optical signal communication can be realized through a photoelectric element positioned at the connector; the power supply of the battery short segments is used for each short segment, and the measurement short segments control the transmission short segments through the optical communication channel formed by the measurement short segments mutually connected in series to transmit a measured signal to the ground.
Description
Affiliated technical field
The utility model belongs to oil field, exploration, probing field, is a kind of directional tool device that data of holes drilled is measured that is used for.
Background technology
At present, the wireless drilling inclinometers that known wellbore construction is used, all a plurality of pipe nipple cascades are formed, and comprising: power supply pipe nipple, centralizer pipe nipple, transmission pipe nipple, deviational survey pipe nipple, GR pipe nipple, resistivity pipe nipple etc.Adopt a plurality of pipe nipples to be connected into a cover complete machine and transferring to the shaft bottom as required, the data of measurement are sent to ground by mud-pressure pulses or electromagnetic mode.The advantage of this method is to select for use different pipe nipple scenes to be combined as the instrument of difference in functionality as required, shortcoming is axially to rotate when being threaded between each pipe nipple, also need to carry out the connection of axially static multicore connector, must specialized designs can guarantee the radially connection of connector for this reason, again can be by the thread seal structure of screw shell connection, its in the connector position under the situation of down-hole high temperature, sharp pounding, be easy to make performance of connector to change to cause connecting unreliable and application life short.
Summary of the invention
For the deficiency that exists in the wireless drilling inclinometers technology that overcomes existing connector connection, it is easy to be reliable to make that instrument connects, and the utility model provides the wireless drilling inclinometers that adopts optic communication between a kind of pipe nipple.Power supply between pipe nipple relies on shell that is threaded and the electricity that is positioned at joint center CONTACT WITH FRICTION to strike the post and provides, the photoelectric cell of the two-way communication of the communication between pipe nipple by being positioned at joint location is realized, communication process does not need the physics contact, realize the noncontact optical signal communications, cancelled the multicore connector of communication usefulness, make be transmitted in each pipe nipple to patch the position more safe and reliable.
The scheme that its technical problem that solves the utility model adopts is: adopt the wireless drilling inclinometers of optic communication to comprise battery pipe nipple, centralizer, measurement pipe nipple and transmission pipe nipple.Measure attitude and geologic parameter that pipe nipple measures well, produce mud pressure signal or electromagnetic wave signal by the transmission pipe nipple.The beneficial effects of the utility model are: each pipe nipple does not need the multicore connector when connecting, and has increased the reliability of underground work, makes that on-the-spot replacing pipe nipple is fast rapid yet.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified:
Fig. 1 is the overall connection layout of the wireless drilling inclinometers of employing optic communication of the present utility model.
1. battery pipe nipples among the figure, 2. centralizer is 3. measured pipe nipple, 4. the transmission pipe nipple.
Fig. 2 is the part figure of optic communication blank area in the utility model.
5. electricity are struck the post among the figure, 6. optoelectronic transceiver diode, 7. spring, 8. shell
The specific embodiment
Battery pipe nipple (1), centralizer (2), measurement pipe nipple (3), centralizer (2), transmission pipe nipple (4) are from top to bottom in proper order respectively by being threaded in Fig. 1.In the joint that per two pipe nipples connect, metal shell (8) is by being threaded as the negative pole of system power supply, the joint center connects positive pole as power supply by electricity (5) friction of striking the post, electricity strike the post (5) and shell (8) between the part radial arrangement 6 groups of optoelectronic transceiver diodes (6) are arranged, electricity is struck the post and spring (7) is installed after (5), by spring (7) compression increase friction.After any two pipe nipples put in place by being threaded, the electricity of two pipe nipples strike the post (5) rely on the pressure contact of springs (7).The optoelectronic transceiver diode (6) that lays respectively at two short joint positions maintains certain distance, thereby the light that sends can be received by the other side and realizes optic communication.During complete machine work, battery pipe nipple (1) provides power supply by strike the post by screw thread that is linked in sequence and the electricity that connects successively (5) for complete machine.Centralizer (2) connects each pipe nipple of down-hole, for it provides damping and sets upright; Because inner use is the very strong beryllium-bronze of toughness, so can also provide necessary flexible bending for whole instrument.Measuring pipe nipple (3) is used under the production wells relevant parameter and uses the optical communication system control transmission pipe nipple (4) that connects step by step to send signal and transfer to ground.
Claims (2)
1. wireless drilling inclinometers that adopts optic communication, by battery pipe nipple, centralizer, measurement pipe nipple, centralizer and transmission pipe nipple from top to bottom order form by being threaded respectively, it is characterized in that: the electricity that uses the screw thread that is positioned at metal shell when per two pipe nipples connect and the be positioned at joint axial centre CONTACT WITH FRICTION formation current supply circuit of striking the post.
2. according to the described inclinometer of claim 1, it is characterized in that: realize the noncontact optical signal communications by the photoelectric cell that is positioned at joint location when per two pipe nipples connect.
