Description

The high-precision ultrasonic storing flow
Technical field
The utility model relates to a kind of downhole fluid flow, pressure and temperature parameter flow meter for measuring water injection well in oil fields, is specifically related to a kind of high-precision ultrasonic storing flow.
Background technology
The accuracy of water injection well monitoring is directly connected to production capacity and the production efficiency of oil field block, and downhole flowmeter is the most general downhole tester of domestic application.The major part that water injection well in oil fields injects is sewage, and subsurface environment is abominable, and shaft bottom silt sump oil etc. is blended in water, has a significant impact for the Measurement accuracy fluid flow.Existing flow meter mostly is electronic grout flow meter, causes in Machine Design limitation very large, and the movable parts such as baffle plate wherein and spring are subjected to the down-hole Impact factor to make together that fault rate is high, and maintenance is inconvenient, and to also having a significant impact on accuracy of measurement.
Although a small amount of ultrasonic flowmeter of using, can only satisfy high flow and measure at present, the water injection well accuracy of measurement low for discharge capacity is difficult to reach requirement.
Summary of the invention
In order to overcome the deficiency that exists in background technology, the utility model provides a kind of small displacement down-hole ultrasonic flowmeter, has solved existing flow meter complicated in mechanical structure, and the high maintenance of fault rate is inconvenient, and to the not high difficult problem of the small displacement well measurements degree of accuracy.
The technical solution of the utility model is: this high-precision ultrasonic storing flow comprises the fishing head rope socket, the described fishing head rope socket lower end upper centralizer that is threaded, in upper centralizer, battery is installed, upper centralizer lower end screw thread is connected with housing, circuit board is installed in housing, circuit board and battery are pegged graft, be separately installed with ultrasonic probe in housing middle part and bottom, ultrasonic probe is connected with the circuit board signal line, housing corresponding to ultrasonic probe be along circumferentially being evenly distributed with bar hole, and housing lower end screw thread is connected with centralizer.
The utlity model has following beneficial effect: this instrument adopts non-collective flow formula ultrasonic flow rate principle, can be because of the difference of rate of flow of fluid when transmitting in liquid due to ultrasonic wave, cause the phase difference that transmits and receives between waveform, and this phase difference and flow velocity have relation one to one, so by detecting the phase place extent, can calculate the size of flow.This serial Instrument measuring precision is high, rise survey that discharge capacity is low, the scope of application is wide, high temperature resistant, corrosion-resistant, to water quality without specific (special) requirements.
