Pressure transducer tester and portable pressure transducer test device
Technical field
The present invention relates to pressure transducer technical field of measurement and test, is a kind of pressure transducer tester and portable pressure sensing
Device test device.
Background technology
MWD wireless drillings measuring system or RWD wireless drillings measuring system using pressure transducer be by down-hole pulse
The drilling fluid pulse signal that generator is produced is converted into the key device of the signal of telecommunication, and pressure sensor senses standpipe mud pressure becomes
Drilling well head of liquid pulse signal is converted into into the signal of telecommunication after change, decoding device is sent to, hole deviation, side is then processed and be reduced into
The data such as position, tool-face, as work under bad environment is easily damaged.The pressure transducer profile of the MWD of different manufacturers production
Structure is different from, but principle and effect are identicals, i.e., when pressure is acted on the diaphragm of pressure transducer, resistance value is sent out
Changing and a linearizing signal output being directly proportional to actuating pressure is produced, Jing after processing system process, be reduced into
Required project data.At present, the mwd system of each directional well company configuration is by different manufacturers production, its instrument and pressure sensing
Device structure, model are differed, wherein it is conventional have that Beijing is sea blue, it be open-minded in Beijing and the pressure sensing of Beijing six directions production
The sea blue pressure transducer produced with apocalypse open-birth in Beijing of device, wherein Beijing is diffusion silicon type, the electric current adopted international standards
Signal, its current signal are 4-20mA, and the pressure transducer of Beijing six directions production is that battery is powered, and that it is given is I-WIRE
Protocol signal, its signal are sensor voltage signal is converted by the DS2431 chips of Maxim MAXIM.
Because currently without special pressure transducer tester and portable pressure transducer test device, in detection pressure
During sensor, pressure transducer can only be connected on standpipe is together carried out with instrument test, and this method can only detect pressure
The pressure of sensor, and can not detect whether the circuit inside which is normal, by the conventional pressure transducer through test
Normal function rate statistics find, through test pressure transducer normal function rate be only 30 percent, work as pressure
Pressure transducer can only be unloaded from standpipe during sensor fault, this need expend 30 minutes, first have to termination of pumping, fall low pressure after
Pressure transducer can be just unloaded, new pressure transducer is then changed and is tested again, this construction that not only have impact on drilling team is entered
Degree and work efficiency, also increase the labor intensity of engineering staff.Due to without the test dedicated for detection pressure transducer
Device, it is impossible to pressure release sensor and check miscellaneous equipment, be so greatly increased exclude instrument failure time, increase
Add the labor intensity of engineering staff, reduce work efficiency.

In field operation, suspect that sometimes the abnormal instrument signal for causing of MWD sensor is abnormal, need to change pressure biography
Whether sensor, with failure judgement as sensor causes, but during replacement operation, need termination of pumping and empty the mud side in standpipe
Replaceable, if the pressure transducer changed is inherently problematic, it is bad to be, engineering staff will exclude sensor after replacing
Reason, but changed this later, change that ground installation is normal, sensor typically just will be considered that it is to be broken, and be given up
Abandon.But sometimes spread silicon formula pressure transducer be not it is non-well i.e. bad, due to spread silicon it is aging or circuit aging, pressure sensing
There are one and half half bad states in device(Situation seldom, simply found one in the several sensors changed), sometimes
It is that pressure is forbidden(Such case has substantially no effect on the use of MWD wireless drift indicators), sometimes response speed is slack-off(Such case
User can feel that instrument is not in harmony, but have signal, and simply waveform is a bit strange, allow people to be difficult to judge, may suspect mud
Slurry performance, or ground or the underground part of MWD instruments.)

Hidden danger, so as to effectively save human and material resources, financial resources, mitigates labor intensity of the engineering staff in the operation, improves its work
Efficiency, and then high-quality guarantee is provided for drilling team's deviation prevention and fast.
When actually used, when anti-misoperation switch 8 is pulled to centre position, instrument quits work, and turns round sub- handle and pulls upwards
Dynamic, the first sense light 7 lights, it is adaptable to sea blue and middle day pressure transducer, turns round sub- handle and pulls downwards, and the second sensing refers to
Show that lamp 9 lights, it is adaptable to six directions pressure transducer;Afterwards, on 1 rear end of correspondence cabinet bulk the first aviation socket 5, the second aviation
Socket 6 or the 3rd aviation socket 18 connect the pressure transducer of dimension, for the middle day pressure sensing for coming with armored cassette
Device, installs the connecting line of aviation plug by one end with alligator clamp one end, and aviation plug is accessed the first aviation socket 5, will
Alligator clamp is connected on the binding post in armored cassette, can conveniently connect sensor, for sea blue pressure transducer
The aviation plug of its terminals is arranged on into the 3rd aviation socket 18 directly, for six directions pressure transducer is directly connect
The aviation plug of line end is arranged on the second aviation socket 6;If not connected sea blue or middle day pressure transducer, or sensing
When device circuit disconnects, sensor digital display instrument 4 shows -6, connects but sensor digital display when pressure transducer does not bear fluid pressure
Instrument 4 shows 0, and when pressure transducer has pressure, sensor digital display instrument 4 shows relevant pressure, and LED light post display instrument 11 is applied to existing
Field detection pressure oscillation, turn on pump when being connected on standpipe, if down-hole MWD instruments are working properly, LED light post display instrument 11 can show
Show corresponding regular pressure oscillation situation.
Above technical characteristic constitutes embodiments of the invention, and which has stronger adaptability and implementation result, can basis
The non-essential technical characteristic of increase and decrease is actually needed, the demand of different situations is met.
