Exploration is an important part in oil and gas field development, and oil exploration personnel use geological knowledge to research underground geological conditions, know structural characteristics and sedimentary strata, combine oil reservoir description research, oil reservoir engineering research and other technical subjects, and reasonably arrange research work of links such as drilling, logging, well cementation, well completion and the like. With the construction of oil field digital work and the rapid development of the information era, an exploration and production information system becomes one of important portals of petroleum and is mainly divided into four parts, namely production dynamics, production results, reserve results and shaft curves. The well bore curve is a precious data resource in the exploration and development process and is the key point in information work. Wellbore data is various data information obtained from drilling work around a well, and mainly comes from exploration information data such as logging, drilling, logging, oil testing, development and the like.
Before information construction, because different departments manage data information of different specialties, well bore curves are divided into twenty types in total, such as well logging curves, comprehensive curves, special well bore curves and the like, and various data are complex. Because the data volume of the shaft information is huge, geological researchers are required to collect data when drawing the graph, and then graph drawing is carried out through single-machine software, so that a large amount of manpower and material resources are consumed; meanwhile, a uniform drawing standard is not established in the drawing aspect, and difficulty is caused to the storage and the viewing of data. The traditional exploration shaft curve drawing greatly influences the development efficiency of geologists. At present, in the aspect of webpage-version shaft curve drawing, a drawing scheme based on SVG and Canvas exists, wherein the SVG is a language defined by XML and is used for describing two-dimensional vectors and vector/grid graphs; a Canvas may use a script (usually JavaScript) to draw the HTML elements of the image within; however, these schemes have the disadvantages of unsmooth drawing, slow response speed, unsmooth lines, etc. due to the defects of the underlying technology and the architectural design.
