| As the popularization of computer application technology in geology,it has added new energy to the digitization of rock stratum research.With the depth and refinement of exploration work,the geological workers have higher requirements on the research of the digitalization of rock stratum,such as the accuracy of geological map drawing,the speed of drawing and the accuracy of stratigraphic prediction.Aims at the shortcomings of the traditional method and technical scheme of the Mechanical rock formation digitization,this paper explores the method of the formation digitization modelling and the realization of computer visualization based on the genetic linkage.The main content is as follows:First,the numerical method of one-dimensional rock stratum description is explored.The basic model of one-dimensional of rock stratum description is established by comparing the self-similarity between the rock stratigraphic unit and the basic rock stratigraphic unit.Then,according to the characteristics of the standard legend of rock symbols,the related rock symbol library is established.Lastly,it takes the iterative operation of the rock symbol entity as the basic way to realize the visualization of the frame content of the stratigraphic section diagram.Second,based on the above theoretical method,a set of software system which can be used to describe one dimension rock stratum is developed by systematic analysis and design.The functions of this system contains data inputting,automatic mapping,drawing editing and file export.The correctness and practicability of the system are proved by the application example of the measured stratigraphic profile in cold Water Creek.Third,on the basis of previous work on quantitative study of rock formations,this paper further perfects the mathematical equation,which starts by analysing the mathematical characteristics of the sedimentary bottom curve of the rock formation,then gradually derives the lateral accretion principle.Thus the theory and method of the numerical model of the sedimentary process of the rock formation is proposed and the solution of the equations is optimized.Finally,combined with computer graphics and three-dimensional visualization technology,the software of the lateral additive equation is realized,and a parameterized two-dimensional sedimentary process simulation system is established.The scientific and feasibility of the system is preliminarily validated by reference to the typical sedimentary environment and its physical parameters.Above research showed the new scientific exploration in the field of the digital direction of the rock stratum,the formation of one-dimensional rock stratum digital description System has been registered in computer software Copyright(Registration number:2016SR224647).It not only provides a new technical means for geologists,but also provides a new model for concisely expounding the sedimentary law of strata.The primary rock stratigraphic sedimentary simulation system based on the lateral additive equation provides new ideas for exploring the sedimentary process and predicting the spatial shape and scale of the geologic body.Especially in oil and gas resources exploration,regional geological survey,geological mapping and other fields,it has important theoretical and practical significance. |
