Problems solved by technology
In the prior art, most of the evaluation and analysis methods for the stability of rock slopes are aimed at a certain topic, or are analysis and evaluation methods with a single research method, and there are relatively few systematic and comprehensive analysis and evaluation methods.
There are also many problems: such as ignoring the geological environment conditions of rock slopes, etc., so that the accurate prediction of rock slope stability cannot be obtained, and the optimal selected pressure drop cannot be obtained according to the stability prediction, so the optimal pressure drop cannot be used. The pressure drop of the top is optimized for production, and the detection of problems in the drilling process or production process cannot be displayed in real time, and production safety cannot be guaranteed

Embodiment Construction
[0044] According to a preferred embodiment of the present invention, an interactive display device is provided, which can directly and graphically display the situation when the rock slope around the wellbore is in the predicted fracture state, using three-dimensional image display and "click and drag" interface changes The azimuth of the well can also be simply selected for earth parameters and drilling parameters. Displays are used to quickly and accurately communicate differences between boreholes drilled in different directions and at different angles, as well as the effect of changes in soil weight on borehole differences, in situ pressure and rock slope properties. It can also be used as an interactive tool for comparing predicted deformation patterns against drilling data, for example to establish upper and lower bounds on the stress state. According to one embodiment, an oilfield service engineer responsible for designing a well for a client will display a fully functi...

The invention provides a display method of a rock slope interactive stability display system. The method comprises the following steps that a program is initialized, and a group of default parameters is read; the rock stability in the periphery of a borehole is predicted on the basis of a present parameter; a 3D display device is used to display the predicted rock stability in the periphery of the borehole in real time; whether the parameter provides a proper result for the rock stability of the periphery of the borehole is determined, and if a user determines the present parameter is proper, a well drilling process is continued; and otherwise, the user changes an input parameter by moving a clicking device and / or carries out calculation again by changing the parameter value in a data input box. Thus, the rock slope stability is predicted, an optimal selected pressure drop is obtained according to stability prediction and is used for production, problems occurred in the drilling or production process of are displayed in real time, and safe production is ensured.
Description
technical field [0001] The invention relates to a slope stability display system, in particular to a method for displaying stability by means of estimated interaction. Background technique [0002] Slope is a kind of landform widely distributed on the surface, and the study of slope stability has always been a key research object in the field of geotechnical engineering. There are many types of slopes, including natural slopes and artificial slopes. According to lithology, they can be divided into rocky slopes and soil slopes. Due to the huge hazards of slope instability and widespread occurrence in all parts of the world, slope instability is listed as one of the major geological disasters worldwide, and its research is focused on it. The deformation and destruction of rock slopes usually cause extremely serious loss of life and property to human engineering activities. So far, the methods used for slope stability analysis can be roughly divided into two categories: quali...
