Top drive simulation system and method

Abstract

The invention discloses a top drive simulation system and a method. The simulation system comprises top drive simulation operation equipment, a PLC (programmable logic controller) and a control unit, wherein the control unit comprises a main control machine, a parameter machine and a graph processing machine; the top drive operation equipment is connected with the PLC; the PLC is connected with the parameter machine through a serial port, and the parameter machine and the graph processing machine are respectively connected with the main control machine through a communication network. The simulation method comprises the following steps that S1, switch and knob state data are collected; S2, the data are sent to the main control machine; S3, the main control machine carries out calculation; S4, virtual showing is carried out. The invention provides the top drive simulation system and the method. The system has the advantages that the occupied ground is small, the maintenance cost is low, the damage cannot easily occur, the full-dimension and full-physical operation environment can be provided, the strict underground mathematical simulation is adopted, so the system and the method conform to the real process requirements, and meanwhile, the system has the top drive work principle 3D (3-dimensional) animation display function, so that trainees can better understand the top drive work principle and a wearing part maintenance method.

Description

technical field [0001] The invention relates to the field of petroleum drilling simulation, in particular to a top drive simulation system and method. Background technique [0002] Over the years, oil drilling has relied on the rotary table of the drilling rig to drive the kelly, the drilling tool, and the drill bit to rotate for drilling operations. In recent years, with the continuous development of drilling equipment and technology, in order to better meet the needs of drilling special craft wells, in the 1980s, foreign countries developed a combination of faucets and motors to drive drilling tools in the upper part of the derrick space. The drill bit rotates and can be sent down the drilling device along the guide rail placed in the derrick. It is also equipped with a screw thread device for loading and unloading the drill pipe, which can complete the downhole drill string rotation, circulating drilling fluid, drilling pipe loading and unloading, and unloading.

Problems solved by technology

However, for new oilfield employees or petroleum-related majors, they have no perceptual understanding of the drilling process, the steps of downhole operations, and the handling of emergencies. Once there is an operation error or carelessness, it may cause a major accident. bring a lot of loss

Therefore, pre-job training and professional skills learning for drilling personnel are very important. However, conventional classroom theoretical teaching or laboratory operations are not vivid and realistic enough to provide intuitive operation training, which makes the training effect poor and cannot achieve the expected results.
