Gas production simulation system and simulation method

Abstract

The invention discloses a gas production simulation system and a simulation method. The gas production simulation system comprises a gas production simulation device, a PLC (programmable logic controller) controller and a control unit; the control unit comprises a main control computer, a parameter machine and a picture processor; the gas production device is connected with the PLC controller, and the PLC controller is connected with the parameter machine through a serial port; the parameter machine and the picture processor are respectively connected with the main control computer through a communication network; the gas production simulation method includes PLC data collection, calculation of the main control computer and virtual presentation. According to the gas production simulation system and the simulation method provided by the invention, the shortcoming that the pipe network flowing condition is hard to calculate in real time by a traditional calculation method can be solved, pressure and flowing conditions of the pipe network can be calculated in real time, and simulation of leakage, blockage and super-pressure accident can be conveniently carried out; moreover, the floor area of the device is small, every student can intuitionally observe the response action of every gas production simulation device and really reach a highly simulation effect; thus the training scene feeling is enhanced and the training effect is improved.

Description

Technical field [0001] The invention relates to the field of natural gas production simulation, in particular to a gas production simulation system and simulation method. Background technique [0002] Petroleum and oil fields often store natural gas resources in addition to petroleum. Therefore, natural gas must be extracted at the same time in the process of oil extraction. Gas extraction engineering is a dominant system engineering in natural gas extraction engineering, which is beneficial to the high efficiency and high recovery of natural gas fields. Yield development plays a pivotal role. [0003] However, for new employees in oilfields or oil and gas-related majors, they have no perceptual knowledge of gas production processes, separators, heating furnaces and other equipment or handling methods in case of accidents, and they are not familiar with on-site gas production operations. Once operating errors or carelessness occur, serious quality accidents or safety accidents may...

Problems solved by technology

However, since almost all drilling sites and facilities are distributed in the wild, it is impossible to carry out training on site. If only relying on conventional classroom teaching or laboratory operations, due to the lack of vivid, intuitive and vivid auxiliary means and methods, it is inevitable to fall into the The embarrassing situation that the course content is simple and boring, and the learning effect of the students is poor, and the training is difficult to achieve the expected effect

[0004] The traditional gas production simulation training uses real equipment for training, and the internal air is used as the medium to simulate the flow of natural gas. The traditional simulation training is a pressurized equipment, which has potential safety hazards. There is fluid inside, and the system is expensive to maintain and easy to damage. The data of pressure, temperature and flow are very different from those on site, unable to reflect the working conditions on site, the training effect is poor, the airtightness requirements are high, the equipment is expensive, and there are certain requirements for equipment materials, usually only standard parts can be used, and it is difficult to simulate leakage , blockage, valve damage, freezing and other accidents, all equipment must be physically connected, which makes the equipment layout more difficult and covers a large area
