Abstract
The utility model discloses an intelligent single-well three-phase flow counter which comprises a signal collection box arranged in the well mouth pipe lines, a gauge head arranged on the wall of a measuring room and a GPRS data transmission system. A Venturi tube is provided inside the data collection box and the two ends thereof are successively connected with a differential pressure sensor, an even curved pipe, a temperature sensor, a differential pressure sensor and a pressure sensor. The gauge head includes a front panel and a rear panel. The front panel is provided with a display screen and a key board and the rear panel is provided with a circuit board, a RS485 communication interface, a data storage device, a wiring post and a plug socket. The front panel and the rear panel is movably connected and integrated. The intelligent single-well three-phase flow counter has the advantages of small volume, low weight, single-well fixed measuring, fast measuring speed, high accuracy, convenient installment and operation, low cost or the like and can be widely utilized in the oil exploration measuring technique.
Description
One, technical field
The utility model relates to flow meter, particularly a kind of intelligent individual well three-phase flow meter.
Two, background technology
Traditional method of measurement is the output object with tens mouthfuls of oil wells, is separated into oil, gas, water three-phase through eliminator, then by being installed in the flow meter on each phase outlet conduit of eliminator, metering output separately.This metering method and metrical instrument exist following shortcoming or deficiency: 1. need to lay a large amount of measuring channels, build metering room, volume is big, footprint area is big, investment is big, cost is high; 2. can not one-well metering; 3. manually-operated refluence journey, sampling, low, the data of chemical examination efficient are inaccurate, untimely, even misrepresent deliberately, fail to report and conceal phenomenon and occur; 4. because every data accuracy rate is low, so can not accurately analyze the geological condition that oil well dynamically reaches block He You district.
Three, summary of the invention
The purpose of this utility model provides a kind of shortcoming or deficiency that can overcome effectively or avoid existing in the above-mentioned prior art, and it is little, in light weight to have volume again, and individual well is installed, and accurate measurement rate height is convenient to maintenance, the intelligent individual well three-phase flow meter that cost is low.
Intelligent individual well three-phase flow meter described in the utility model, comprise the signals collecting case of installing on the well head pipeline, install instrument head and GPRS data transmission system on metering room wall, be installed on the differential pressure pickup that Venturi tube and two ends thereof connect respectively successively in the described signals collecting case, even swan-neck, temperature pick up and differential pressure pickup, pressure sensor, described instrument head comprises front panel and rear board, be installed on display screen and keyboard on the front panel, be installed on circuit board on the rear board, the RS485 communication interface, data storage, prap and socket, front panel and rear board flexibly connect, and are connected as a single entity.
Wherein, described instrument head is connected by electric wire with the signals collecting case.Described display screen is connected with the socket of installing on rear board by its line respectively with keyboard.Described circuit board is electrically connected with RS485 communication interface, data storage, display screen and keyboard respectively.Described GPRS data transmission system is electrically connected with the RS485 communication interface.
The utility model has following advantage compared with prior art:
1, utilize sensor and special measurement piping, rely on large database and intelligent data process chip, the algorithm of regulating based on the automatic coupling and the self adaptation of neutral net, thereby have compliance to the big characteristics of oil well output momentary fluctuation;
2, because built-in number passes interfaces, therefore can count the biography system by GPRS makes things convenient for networking, uploads data, realizes unattended oil well measurement system;
3, utilize the analysis of the differential pressure measurement noise that Venturi tube produces when heterogeneous fluid flows through, can set up the statistical filtering model of noise, obtain the relevant quantitative information of noise and detected variable, thereby set up the practical theoretical model of noise monitoring two phase flow;
4, owing to be provided with even bend pipe, utilize pressure reduction and the pressure reduction of Venturi tube and the special function relation of resistance coefficient of its measurement, can the composite water cut of oil well be calculated.
