Research And Application Of Automatic Splicing System For Downhole Tubing Diagram In Oilfield

Oilfield downhole tubing string diagram is an important content in the design of oil testing project,including wellbore structure diagram in geological design,oilfield downhole tubing diagram in engineering design,well control equipment schematic diagram and surface flow diagram in geological design.At present,the oil testing and production branch company lacks unified management of the pipe string tool legends used by different departments,resulting in the isolation of pipe string information and tool legends;due to the different actual needs of different departments,the drawing and requirements of the pipe string diagrams are also different.Because of the differences,the same system cannot meet all the requirements at the same time;at the same time,due to the different drawing levels of different departments and different designers,the drawing of the same column diagram is very different,and it is difficult to achieve data sharing and unified management between different departments.,Reduce work efficiency.In response to the above problems,this article unified management,design and standardization of the tool legends used by different departments,and then draws and designs the pipe column diagrams required by different departments under the same platform to ensure data sharing between different departments And unified management.To study and realize the automatic splicing system of downhole tubing diagrams in oil fields.1.The tool legends used by different departments are classified and sorted in detail,and the logical structure design of the tool legend tool library is completed.The basic structure and lines of the pipe column tool legend are drawn using this system,and then the texture mapping technology is used to realize the color Adding and lighting processing to realize the drawing of the tool legend,and also realize the upload and maintenance management of the tool legend.2.By using the Scale Invariant Feature Transformation(SIFT)algorithm,the automatic stitching between all the pipe string tool legends is realized,and then the weighted average image fusion algorithm is used to achieve smooth transition of the image and reduce the stitching traces,and then use the texture The mapping method maps the image to the borehole trajectory to realize the drawing of the downhole tubing string diagram in the oil field.3.According to the requirements of the drawing business designed by the oil test project,the three-stage drawing method and Open GL technology are used to realize the drawing of the borehole trajectory,and at the same time realize the functions of rotation,zooming and viewing angle conversion of the borehole trajectory.Through automatic assembly,the drawing of well control equipment and surface pipeline connection schematic diagram in construction design is realized.4.Analyzed the overall requirements of the system,and completed the design of the business process,framework,database and specific functions of the system,developed a tool legend library,automatic splicing of oilfield downhole tubing diagrams,and drawings of well control equipment and surface pipeline connections.An automatic splicing system for downhole tubing diagrams in oilfields.This system not only improves the quality and efficiency of drawing,but also realizes data sharing and unified management between different departments,and achieves the effect of multiple uses and recycling of a drawing.It is of great significance to the development of downhole tubing drawing in oilfields.It also provides references for the development of related systems in other fields,and has certain theoretical and practical significance.
