Description

Oil field wireless telemetering oil well and well pressure data-logger

Technical field

The utility model relates to a kind of pressure-detecting device, specifically a kind of oil field wireless telemetering oil well and well pressure data-logger.

Background technology

At present, the pick-up unit that the pressure of oil well and well is detected in the oil field, a kind of is the mechanical pointer tensimeter that is screwed on the well head, and another kind is to need the on-the-spot numeral of being made up of pressure transducer and read out instrument of power supply that provides to show pressure unit.There are two obvious defects in the mechanical pointer tensimeter: the one, and measuring accuracy is low, and the 2nd, can't know the temporal information of image data and the position of oil well or well.Numeral shows pressure unit, though can improve measuring accuracy, but each pressure transducer all is equipped with the one's own read out instrument of a cover, and need set up supply line, for showing pressure unit, numeral provides interchange or direct supply, thereby the cost of realizing pressure detection is higher, and numeral shows that pressure unit itself and supply line also easily by artificial destruction, cause damage.In addition, numeral shows that pressure unit equally also can't know temporal information and the oil well or the well position of image data.

The wellhead pressure that all needs repeatedly regularly to detect every mouthful of oil well and well in the oil field every day.For the oil that prevents to exploit out or be used for the pick-up unit of oil well and well pressure detection stolenly, generally adopt two kinds of methods: a kind of is the band password of theft-proof box take to install additional to(for) barreler, will open theft-proof box with password during detected pressures.Another kind is for stripper well and water injection well, does not take anti-theft measure at well head usually, after the detected pressures measuring instrument is taken off and takes back, and also has measuring instrument is welded on situation in the antitheft cover.All need every day repeatedly regularly to open theft-proof box or repeatedly regularly at the well head tensimeter that spins, labour intensity is big on the one hand, has personal safety hidden danger for high-pressure water injection well on the other hand with password.

Because have only according in official hour, determine position and the data detected pressure value of oil well and well accurately, could provide reliable basis for well stimulation, for the production run in oil field is made regulation measure targetedly.Help in time finding pipe laying alluvial or block, in time take measures, reduce production loss.

The utility model content

The purpose of this utility model just provides and a kind ofly uses interior powered battery, can discern wireless telemetering oil well and the well pressure data-logger that well head numbering, image data have temporal information and can use for a long time.To overcome the deficiency that existing pick-up unit exists, satisfy the on-the-spot test safety that improves in oil field, alleviate labor strength, effectively improve and patrol the well quality, guarantee the use needs of fundamental analysis data accuracy.

The utility model is achieved in that wireless telemetering oil well and well pressure data-logger include the intelligent pressure collector of installing at well head with radio transmission-receiving function and have the demonstration of radio transmission-receiving function and the hand-held instrument of patrolling and examining of storage pressure and well head number information.

Design philosophy of the present utility model is exactly that the numeral that will be made up of pressure transducer and read out instrument shows that pressure unit is separated, the intelligent pressure collector of being made up of pressure transducer, signal condition and radio transmission-receiving function circuit etc. only is installed on well head, digital display portion then correspondingly is made for a public hand-held instrument of patrolling and examining, and removes to detect the pressure data on every mouthful of oil well and the well accordingly.The utility model is on the basis of usual pressure sensor for this reason, increase a small-sized high-energy battery and comprise the signal processing system circuit that signal condition, signal processor, wireless communication interface etc. are formed, but data such as zero point of pressure transducer, calibration coefficient K value identiflication number are deposited in wherein, constitute an intelligent pressure collector.The intelligent pressure collector is by built-in small-sized high-energy battery power supply, and when not needing to detect wellhead pressure, the intelligent pressure collector is in power down mode (off-mode or standby dormant state) automatically.

When carrying out the wellhead pressure detection, the public hand-held instrument of patrolling and examining is aimed at the intelligent pressure collector on the check point, patrol and examine identiflication number, range and the pressure data that instrument can start and read this specific intelligence pressure acquisition device by wireless mode but hand, through hand-held logging list processing (LISP), pressure data is presented at hand-held patrolling and examining on the display screen of instrument, simultaneously with pressure data, acquisition time (patrol and examine instrument and provide) by hand-held but identiflication numbers etc. are stored in hand-held patrolling and examining in the instrument.

The utility model shows pressure unit with the numeral that the intelligent pressure collector with radio transmission-receiving function simple in structure replaces complex and expensive, has saved a large amount of read out instruments.Powered battery in the utility model uses does not have at the scene and can carry out under the condition of power supply discerning wireless oil well and the touring detection of well pressure that oil-water well is numbered, image data has temporal information.The utility model both can reduce production costs, and can reduce construction and operation and maintenance cost again, simultaneously again because only when touring the detection intelligent pressure collector just power up work, thereby improved the serviceable life of pick-up unit.Use of the present utility model; need not to open theft-proof box when making detected pressures; can be outside theft-proof box or antitheft cover the wireless pressure that reads; test safety is convenient; alleviate labor strength greatly; effectively improve and patrol the well quality; can impel the personnel of patrolling and examining to obtain reality, useful, data detected pressure value accurately in official hour, definite oil well and well position; help guaranteeing the accuracy of fundamental analysis data; thereby could make targetedly reasonably regulation measure for the production run in oil field; for well stimulation provides reliable basis, promote the production in oil field.
