The Design And Implementation Of Drawing Modules Of Pressure Planar Graph And Profile

Which is the explanation of geological information system,the isoline Map of formation pressure is a important geological materials. The isoline map is conmbined with data and figue ,and make geologist observeing exactly the trend of data ,analyses directly regularity of change of geological parameter.As a geological or formation parameter , initial formation pressure covers a very important basis in petrogeological exploration,Drilling Engineering,oil-gas exploition and reservoir engineering.It can help us to research hydrocarbon migration,accumulation condition and law;to predicting the possible oil gas enrichment area and favorable horizon;to study on the tectonic sealing conditions.This article tried to use some information ,such as seismic,geology,logging with logging,drilling and testing,to establish a much more accurate forcast plane and section plane map of formation pore pressure.During the protract of pressure planar map and profiles map,its study and apply the Inverse Distance Power method ,Kriging,Shepard's method,triangularmesh/ linear interpolation method.This article focused on the principle and implementation methods of drawing isoline, and the specific methods of the data extraction in pressure, mesh generation and discrete data grid are given; in the contour tracing and search for the extension direction design to use the elliptical method .To ensure that a comprehensive follow-up; in elevation contours of the value of the mark cut-off mark in the design ways to enhance the appearance of the graphics degrees; The editing and graphics of fault,unconformity and lithologic trap such as features in the section mapping.is developed. Systems using the object-oriented programming approach to development, the navigation function of vector graphics is realized, while the system-generated maps storage in vector graphics format. more geological information,flexible and diversified result maps output methods are given.The results of the pressure planar map and profile map which have already researched and develpoed can help the researchers more convenient and accurate study the initial formation pressure in the horizontal and vertical distribution,analysis its law of changes and bearing pressure mechanism,divide the pressure system,and provide the necessary basis for exploration well locations and drilling project.Use this system to wildly study the Dongying's depression prssure system.This system combine with the predictive of pressure tracking in exploration well,and form a new series of technology.To make the precision of pressure predition of exploration well enhance to nealy 3%,and also improve the economic efficiency of integrated exploration.
