System and method for simulating borehole operation

Abstract

The invention discloses a system and a method for simulating borehole operation. The system is that each of a well repair driller's console system, a choke control panel system and a blowout prevention control panel system comprises a PLC, a front end operation input device and a front end output display device; each front end operation input device comprises a plurality of switches, knobs and valves; each front end output display device comprises an indicator light, a pressure gauge and a thermometer; a main control computer is equipped with a calculating module which is used for calculating the indicator light state, pressure gauge data, thermometer data and working condition data of a device in a virtual scene through a mathematical model according to the switching state, the knob value and the valve opening degree data; a virtual presentation module is arranged on a graph processor and used for presenting the simulated real field scene and the device working condition according to the working condition data of the device in the virtual scene. According to the system and method, the real device is highly simulated, and thus students can easily understand and master; the system is safe to use; the intelligent scoring is performed, so that the fairness and justice are ensured; in addition, the problem of wrong operation can be accurately pointed out.

Description

technical field [0001] The invention relates to a drilling simulation system, in particular to a downhole operation simulation system and method. Background technique [0002] Oil drilling refers to the process of using special drilling equipment and technology to drill a cylindrical hole with a certain diameter downward or on one side at the surface position where oil storage is found after exploration, and to drill into underground oil and gas layers. To realize oil and gas production, it is necessary to Proficiency in the professional knowledge and operational skills of oil drilling. Downhole operation is a technical means to ensure the normal production of oil and water wells in the process of oilfield exploration and development, and it is a workover operation to maintain the normal long-term normal production process. [0003] However, for new oilfield employees or petroleum-related majors, they have no perceptual understanding of the drilling process, downhole operat...

AI Technical Summary

Problems solved by technology

[0006] ①The cost is very high, a large site is required, and the equipment is difficult to shrink. The cost of shrinking equipment is more expensive if it is not mass-produced;

[0007] ②Because there is fluid inside the pipeline, the use and maintenance costs of the system are high;

[0008] ③ It cannot show the internal flow of the equipment;

[0009] ④ Operation errors may cause danger;

[0010] ⑤ It is difficult and dangerous to simulate leakage and pipe blockage accidents

[0012] ① No workover simulation equipment;

[0013] ② Cannot simulate workover operations, and cannot display important workover accidents and corresponding treatment methods;

[0014] ③More complex and expensive than workover
