Method for simulating gas expansion for drilling simulator

Abstract

The invention discloses a method for simulating gas expansion for a drilling simulator, which comprises the following steps: (1) reading state parameters and operating orders of front-end equipment; (2) according to the acquired equipment state parameters and the types of the operating orders and a pre-established gas expansion model, calculating data for realizing a gas expansion simulation cartoon; (3) according to a set data format, communicating with a specialized graphic processor unit, exchanging operational data, and then accordingly finishing the cartoon representation of the gas expansion in a drilling process by the graphic processor unit; and (4) according to the set data format and the graphic processor unit for communication, exchanging the state information of the cartoon. Based on computer stimulation technology and according to the on-site actual situations of drilling operation, vivid stimulation of the process of generating expansion when the gas overflows in an annulus and goes upwards in the drilling process is carried out, so that the presence of teaching training is enhanced, the training period is shortened, the training effect is improved, and the training cost is reduced.

Description

Technical field [0001] The invention relates to a drilling process simulation method of a drilling simulator, in particular to a gas expansion simulation method of a drilling simulator. Background technique [0002] The petroleum industry is a technology-intensive industry, and drilling operations are one of the important means for the petroleum industry to acquire reserves and increase production capacity. Due to the limitation of oil drilling production conditions and the complexity of downhole conditions, oil drilling operations face great risks. In order to obtain better production efficiency and economic benefits, and reduce the occurrence of man-made accidents, the training of technical skills for drilling site operators and engineering technicians is very important. The simulation of the drilling process is an important part of the drilling process, so the simulation of gas expansion in the drilling simulator is also very important. [0003] At present, drilling operation ...
