【摘要】 录井技术是油气勘探开发活动中最基本的技术,是发现、评估油气藏最及时、最直接的手段。开发一套通用性好,有自主知识产权的录井导向系统对我国的石油勘探业具有重大意义。在计算机辅助录井过程中,需要处理大量的矢量图形。计算机根据测井数据,能自动确定油、气、水产状,自动绘制不同类型的录井图。目前很多录井导向系统绘制矢量图形的方式、存储格式各不相同,软件通用性较差,也不便于软件的二次开发。本文通过对矢量图形的三种标识语言进行比较分析,提出以XML格式的文档来存储二维矢量图形。本软件使用SVG 1.1标准作为三维图形的存储格式,在录井导向领域矢量图形的格式与存储方面做出了初步的研究和探索。软件实现了手动调整图形中录井位置与数量、数据录入和修改、根据测井数据全自动生成三维矢量图形等功能。矢量图形可沿Z轴旋转,解决了矢量图形旋转时的遮挡问题。最终生成的SVG图形可以很方便的在主流浏览器中查看,提高了录井图形的通用性,也方便进行系统二次开发。更多还原

【Abstract】 Logging technology is the most basic in the oil and gas exploration and development activities.It is the timely and the most direct means to discover and evaluate the oil and gas reservoirs.The development of an oriented logging system that has good generality and self-owned intellectual property is of great significance for the oil exploration industry in China.In the computer-assisted logging process,a large number of vector graphics need to be operated.According to the logging data,computer can automatically determine the occurrences of oil,gas,and water as well as to draw different types of logging graphs.At present,many logging oriented-systems are different in the ways of drawing vector graphics and storage formats.Besides,software does not have good generality, which is not convenient for its secondary development.This thesis is intended to puts forward that the documents to XML format are used to store two-dimensional vector graphics by a comparative analysis between three kinds of vector graphics markup language.The SVG 1.1 standard software is employed as the storage format of three-dimensional graphics and a preliminary study and exploration is made in the format and storage of logging-oriented vector graphics. Software manually adjusts the location and number of logging in the vector graphics, input and modify data,and according to the logging data,automatically generate three-dimensional vector graphics,vector graphics rotation along the Z-axis rotation, which solve the occlusion issue when vector graphics rotate.The generated SVG graphics can be very convenient for the browser in the mainstream view,improve the generality of logging graphics,and facilitate the secondary development of the system.更多还原
