Description
Technical field
The utility model relates to encoder fields, more particularly, to a kind of drilling well encoder.
Background technique
Currently, exploration and development activity more and more, the worse area of environment more complicated towards strata condition, not
The oil-gas exploration and development object come will be gradually to deep layer, the very severe desert in deep-sea and physical geography position, high mountain and high and cold
Ground transfer.Borehole depth is drilling well, an important parameter in Well Logging Engineering, the parameter of all stratum or casing all with depth
Corresponding, the drilling information for leaving depth will be without any geological Significance.Therefore it is extremely important to obtain accurate borehole depth, this will
It is directly related to the correctness of downhole parameters.Existing depth measurement measures depth generally by encoder, at present
Depth measurement is mostly carried out using optical-electricity encoder in the market, but its head is big, precision is limited, and thermal stability is bad.
Summary of the invention
The purpose of this utility model is that solve the deficiencies in the prior art, and a kind of drilling well is provided
Use encoder.
The new technical solution of the utility model is: a kind of drilling well encoder, including upper housing and lower case, described is upper
It is equipped with stepped hole in shell, sensor holder is installed in stepped hole, sensor is installed in the sensor holder；Under described
Shell is equipped with metallic channel, is equipped with connector base in the metallic channel, is equipped with connector in connector base；It is described
Upper housing in main shaft is installed, described main shaft one end is connected with gland and bearing, is equipped between the bearing and wiring board
Code-disc is pressed with wiring board, and is welded with conducting wire on wiring board between the code-disc and lower case, the conducting wire is pierced by metallic channel
It is connected with connector；The main shaft other end is mounted on the axis of winch drum.
The bearing is 2.
The wiring board acquires the output signal of sensor in real time.
The utility model has the following beneficial effects: the utility model has, shock resistance, small in size, precision is high, response is sensitive, real
With property is strong, structure is simple；Easy to process, installation, and reliable performance；Using high-precision sensor, guarantee the essence to depth measurement
True property；Low in energy consumption, the service life is long, and using effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1 being lower case, 2 be connector, 3 be connector base, 4 be wiring board, 5 be code-disc, 6 be bearing, 7 be
Gland, 8 be sensor, 9 be sensor holder, 10 be upper housing, 11 be main shaft.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
A kind of drilling well encoder, including upper housing 10 and lower case 1, the upper housing 10 is interior to be equipped with stepped hole, platform
Sensor holder 9 is installed in rank hole, sensor 8 is installed in the sensor holder 9；The lower case 1 is equipped with conducting wire
Slot is equipped with connector base 3 in the metallic channel, connector 2 is equipped in connector base 3；The upper housing 10
Main shaft 11 is inside installed, described 11 one end of main shaft is connected with gland 7 and bearing 6, is equipped between the bearing 6 and wiring board 4
Code-disc 5 is pressed with wiring board 4, and is welded with conducting wire on wiring board 4 between the code-disc 5 and lower case 1, the conducting wire is pierced by
Metallic channel is connected with connector 2；11 other end of main shaft is mounted on the axis of winch drum.
The bearing 6 is 2.
The wiring board 4 acquires the output signal of sensor 8 in real time.
Drilling well encoder is convenient and efficient by being threadably mounted on the axis of winch drum, winch drum and derrick phase
Even, when the drum turns, the main shaft 11 of drilling well encoder can be rotated together with roller axis, in this way drive drilling well coding
Code-disc 5 in device rotates, and the sensor 8 of drilling well encoder can collect position data, and output pulse signal, by line
After road plate 4 handles signal, terrestrial interface case is sent to by 2 connecting cable of connector, then will be counted by terrestrial interface case
, to PC machine, corresponding well depth depth is shown after software on ground decodes according to by cable transmission.
