Research And Implementation In Image Display Of Earthquake Datum Interpret System

The interpret of datum is the last stage of earthquake reconnaissance , it has very important meaning for achieving well geological effect .The key of expediting reconnaissance exploitation is how to distill geological information from earthquake datum quickly . The earthquake interpret system is a tool which apply geological datum to earthquake interpret effectively , it can shorten interpret cycle, offer a resort for scanning the shape of conformation, it also offer reconnoiter personnel a resort to distill geological information from earthquake datum quickly.All the interpret result of three-dimensional reconnaissance must be displayed in image information . If there is not a graphics display which can reflect result comprehensively and actually to exhibit the result , it will make the interpret result deficient, so the image is the most important in three-dimensional reconnaissance interpret. The investigation and exploitation of graphics display,graphics operation,graphics filling,optimizing of plot capability in《SEIWAVE earthquake deposit layer forecasting and well deploying system-Three-dimensional earthquake interpret hypo-system》is indispensable.In the three-dimensional reconnaissance interpret system,interpret personnel use earthquake data achieved from earthquake interpret system and the material of well logging,drill and geology to make operation, endow the earthquake data with geological meaning, engender the earthquake section chart. In the analysis of section chart ,it will frequently do the operation of divide up and investigate the exceptional region ,it need to do the operation of reduce and magnify,the magnify and drag of the area which the rectangle selected to the section chart. To analyze conveniently, analysis personnel regularity need to make the operation of background color filling, anode,cathode filling,gradual change filling of anode and cathode to eliminate burr phenomena and mosaic phenomena during the filling process .Earthquake interpret deal with a lot of data , a mass of proportion operation, coordinate conversion and coordinate mapping must be dong in the plot process , it may frequently appears the phenomena of memory deficiency , graphics refurbish in low speed , graphics overlap and twinkle ,so it make use of the technique of memory mapping document, memory DC plotting and local plotting twice and so on to implement quickly and top-quality plotting of lots of gigantic graphics and implement continuous and rolling display.Based on the project named《SEIWAVE earthquake deposit layer forecasting and well deploying system》which is presided by DaQing oil field limited liability company reconnaissance exploitation academe. It implement graphics display module,graphics manipulation module,graphics filling module and optimizing of plot speed in《Three-dimensional earthquake interpret hypo-system》which is the core portion of《SEIWAVE earthquake deposit layer forecasting and well deploying system》.It is deeply investigated the special knowledge of earthquake interpret...
