Exploratory well key information space grading display method

Abstract

The invention discloses an exploratory well key information space grading display method. The method comprises the following steps: S1, obtaining various key information from an exploratory well drilling production process; S2, establishing a three-dimensional scene model of each type of key information in the step S1 based on an observation coordinate system; S3, converting the observation coordinate system coordinates into projection coordinate system coordinates by using a perspective projection model; S4, converting the projection coordinate system coordinates into screen coordinate systemcoordinates; S5, calculating the distance of coordinates representing each piece of key information in the screen coordinate system in the screen coordinate system; S6, making different types of keyinformation into different key information icons on the screen coordinate system coordinates, and the center positions of the key information icons being the coordinate positions of the key information in the screen coordinate system; and S7, determining the display condition of the key information icon by judging the relationship between the distance of the center position of the key informationicon in the screen coordinate system and the size of the key information icon.

Description

technical field [0001] The invention relates to the field of petroleum drilling engineering, in particular to a space hierarchical display method for key information of exploration wells. Background technique [0002] Petroleum exploration mainly obtains underground raw data through drilling activities, and these data are of various types and the amount of data is extremely large. At the same time, oil exploration has the characteristics of high risk and strong unpredictability. It is necessary to provide decision-making basis for follow-up work through the acquired data, so as to reduce construction risk and improve drilling success rate. [0003] Exploration well drilling is the first step in exploration. Data from multiple business nodes such as drilling, well logging, mud logging, and oil testing will be obtained from the follow-up activities of exploration wells. Extracting the key information and displaying it in three-dimensional space is an important demand of the p...

Problems solved by technology

[0004] The traditional method is that when the key information is displayed in 3D, all the data will be displayed at the same time. Often due to the large amount of information, there will be problems such as mutual occlusion and disorder between icons, which also reduces the efficiency of 3D scene rendering and drawing.
