| This paper mainly expounds the development and implementation of the designof imaging software oil-water two-phase matching with the sensor array holding rateinstrument which development by daqing oil field. Software mainly realizes the oil-watertwo-phase flow in horizontal wells in two dimensional, three dimensional dynamic imaging.Software uses Visual Studio2010as development platform, use Microsoft providesMSCOMM control Implementation communication with the downhole instrument, the threedimensional image processing use OpenGL.Imaging software consists of four modules, Data import module is mainly responsiblefor data collection, analysis and filter the data transmitted by the downhole instrument,extracted probe data to useful imaging; Data analysis module is mainly responsible foranalyze and calculate the collected data, to obtain the imaging information required, includingthe oil-water interface height, the oil-water interface width, interface internal probe number,the deflection angle of instrument and water holdup; Two dimensional imaging module ismainly responsible for two-dimensional imaging, in the two-dimensional imaging usingdouble buffer technology to prevent blinking image; three dimensional imaging module ismainly responsible for three dimensional imaging.Do the dynamic and static test for the imaging software, dynamic test execute atsimulated horizontal well which belongs to Daqing Logging&testing services branch, afterimaging experiment software ideal; Method of static experiment is manual to simulatewellbore injection, when the water each not a probe, measurement the interface height, usinga ruler to measure the water curved wellbore and calcuate the water holdup, compared withthe software measured numerical, as expected from the whole perspective computationalimaging and related data.Finally, the functions of the software testing, the software interface is friendly, easy touse, practical, reach the expected goal. |
