Method for simulating overflow for drilling simulator

Abstract

The invention discloses a method for simulating overflow for a drilling simulator, which comprises the following steps: (1) reading state parameters and operating orders of front-end equipment; (2) according to the equipment state parameters and the types of the operating orders and a pre-established overflow model, calculating operational data for realizing a overflow simulation cartoon; (3) according to a set data format, communicating with a specialized graphic processor unit and exchanging initialized data and the operational data; (4) according to the exchanged data, finishing the cartoon representation of the overflow by the graphic processor unit; and (5) 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 operational processes of drilling operation, vivid stimulation of the principle and operation method of overflow is carried out, which is used for the technical skill training of on-site drilling operators and students; therefore, 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 simulation method, in particular to a drilling simulator overflow simulation method. 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 obtain reserves and increase production. Due to the limitation of oil drilling production conditions and the complexity of downhole conditions, oil drilling operations are facing great risks. In order to obtain better production efficiency and economic benefits and reduce the occurrence of man-made accidents, it is very important to train the technical skills of drilling site operators and engineering technicians. Drilling and shutting in are two important parts in the drilling process, so overflow control during drilling and shutting in is very important. [0003] At present, drilling operation training is mainly carried out on the production site. Due to the ...
