SYSTEM volume measuring density and temperature washing fluid intake, slugging tank

摘要

The invention relates to measuring equipment and can be used for measuring the volume, density and temperature of liquids in tanks communicating with the atmosphere in the oil and gas extraction and exploration industries to control the volume, density, and the washing liquid temperature (RV) in the receiving and slugging tank rig during drilling . The technical result of the proposed utility model to provide a volume measurement system, the density and temperature of the washing liquid, to improve the accuracy of determined parameters, as well as improving the system reliability and reduced maintenance complexity by simplifying the structure. Summary of the utility model is that the proposed system of measurement of volume, density, and the washing liquid temperature in reception and slugging tank rig, comprising at least two test modules, each of which represents a structure consisting of two coaxially-arranged tubes connecting the top of the sealed compartment, which houses level meters, pressure and temperature of the washing liquid, the electronics unit, measuring modules are provided with brackets for the mouth tained in tanks and are connected with cables information placards driller. Level meter disposed in a sealed compartment of the measuring module serves to perform a precision volumetric flowmeter reversible counter whose input is connected to the annulus coaxially-arranged tubes, exit to the atmosphere. pressure gauge disposed in a sealed compartment measuring module may be configured as a high-precision quartz pressure and temperature transducer, the input of which is connected with the cavity of the inner pipe providing the fluid to the pressure measurements in the inner tube with a correction for the temperature and calculating values ​​of the density of washing liquid with taking into account the indications of the level meter. The measurement module may further comprise a washing liquid temperature sensor disposed on the bottom of the inner tube and electrically connected to the electronics housed in a sealed compartment. Said washing liquid temperature sensor may be formed as a precision resistor or quartz; thermometer. The electronics module disposed in a sealed compartment sensor module may include an embedded auxiliary power source that provides the continuity of measurement. Coaxially-disposed tubes that make up the measurement modules can be made of high strength fiberglass outer and inner walls of the tubes are coated PTFE film. Information board driller may comprise a keyboard for entering values ​​footprint used containers, borehole diameter, calendar time, the well number, setting values ​​for all parameters, and the like, light and sound alarm on exceeding predetermined set values, the computer (controller) which provides functions for calculating predetermined algorithms based on information inputted from the keyboard and received from the measuring modules for data cables, the total volume of the washing liquid in the tanks and and absorption intensity of the influx while drilling tool, and lifting the indicators measured and calculated parameters and information transmission interface station geotechnical studies on workstation drilling master supervisor and the upper level control the drilling operations.
