An Accident Simulation Method for Drilling Simulation Equipment

Abstract

The invention relates to an accident simulation method for drilling simulation equipment. A simulation device for simulating a land drilling rig is adopted in the method. The simulation device comprises a drilling rig simulator, a front-end operating table, a teacher operating table and a three-channel ring screen projection display system. The front-end operating table internally comprises a parameter computer, and the parameter computer serves as a distributed upper computer to finish data acquisition and control of a whole system and is used for acquiring the position of a winch clutch, the position of a rotary disc clutch and the position of a pump stroke adjuster; lifting control of a winch, speed adjusting control of a slime pump and logic control of a top driver are simulated; hanging loads, bit pressure and torque are monitored, a main control computer and a graph computer finish execution of a main program of the system and processing and display of a ring screen graph, and accident and special condition simulation includes adhesion drilling tool jamming simulation, sand settling drilling tool jamming, mud drum drilling tool jamming simulation, die tap fishing simulation and fallen object grinding and milling simulation.

Description

technical field [0001] The invention relates to an accident simulation method, in particular to an accident simulation method for drilling simulation equipment. Background technique [0002] With the globalization of China Petroleum Technology Development Corporation's business, the drilling rig business has spread all over the world, and developing countries have become the company's main market. With the increase in the number of export drilling rigs, more and more accidents occur during the use of drilling rigs, which may cause damage to equipment, affect production progress, and bring economic losses, or lead to major safety accidents and cause casualties. In particular, several major accidents occurred during the relocation and use of foreign drilling rigs, which had a negative impact on the company's development and image. Drilling rigs belong to construction machinery, and the safe production of construction machinery not only directly affects the service life of the...

Problems solved by technology

[0005] Practical opportunities are limited, and it is difficult to improve the technical level: due to the particularity of drilling operations, the dismantling and installation of drilling equipment often takes several months, even once a year, and it is difficult for operators to accumulate various experiences through practical operations

In addition, in the process of equipment installation and dismantling, the probability of accidents is relatively small, and individuals have very limited experience in handling accidents, and it is difficult to accumulate and improve the ability to judge and deal with accidents in actual production activities

Once an accident occurs, often due to lack of experience and handling ability, it will cause heavy loss of life and property

[0006] Traditional technical manuals and operating instructions are scattered and inconvenient to consult

Some complicated operation processes are difficult to describe clearly in words, coupled with differences in individual understanding, it is very likely to lead to misoperation and accidents
