3.1 Functions and Features
The system provides an immersive logging environment. Gas detection system, explosion-proof system and compound logging software system adopt the devices from production site, which greatly improve the training quality.
Drilling accident simulation software, of which Esimtech Company owns independent intelligent property right, can simulate various accidents in drilling process, totally 6 kinds including 46 items of accidents. The software can playback the real logging data of 5 wells, and simulate drilling process such as tripping in, drilling, circulating, reaming, etc.
Logging software adopts the solution of Riglog developed by Shanghai Oushen Company. Riglog is the compound logging software extensively used in oilfield logging. It can acquire, record data of various sensors and chromatograph, and print the data at real time.
Sensor detection software system contains sensor detection master control software, sensor detection graphics software and sensor detection PLC program. When students don’t know where to install the sensor, they can insert it in the corresponding aviation connector, and the graphics program presents the data of the sensor such as the installing position and measurement range.
PLC program of power control system is mainly used in monitoring H2S sensor, flammable gas sensor, smog sensor and micro difference pressure sensor in logging units. When the sensors launch alarm, the electrical degasser will be powered off automatically.
The system can automatically score student’s operation. It can give score and point deducting reason automatically according to student’s operation procedure.

- What is petroleum simulator?
A simulator is a device that simulates an environment for the purpose of training or research. A petroleum simulator is a set of devices that simulates the well site environment, the real operation devices, the operation method, parameter display way, etc. with which trainees can be access to a virtual well site environment, where they can get familiar with the relative devices, how to operate the devices, what phenomenon there will be if there is a problem, what’s happening underground, etc.
- Why is the simulator necessary to oil and gas industry?
Since the beginning of the 20th century, simulators have been used in different industries as tools to train and to facilitate the growth of the operators of the machinery. This type of training is, without a doubt, one of the most effective ways to mitigate labor risks, develop the skills needed, and increase productivity.
In oil and gas industry, accidents happen from time to time, such as blowout, H2S leakage, fire, explosion, machinery injuries, etc. Working in the oil and gas field is of high risk. According to statistics, almost 36% of these accidents were caused by mistakes in operation. Sufficient pre-post training is essential. A simulator makes this possible, which provides a virtual training environment, for new staff the get familiar with the working environment, site scene, and operation devices in advance. With the simulator, new staff can also experience the common incidents which may occur in real operations, and learn to judge and handle emergencies. So that in real work, most of the accidents can be judged or avoided in an early stage, and therefore reduces risks and increase production.
- What well control simulations does this well control simulator cover?
In well control operation, pressure control is very important. How the pressure is controlled? In the good control simulator, various scenes of kick can be simulated, both hard and soft shut-in procedures can be carried out. Meanwhile, various well-killing methods are provided, such as driller’s method, engineer’s method, volumetric method, bullheaded, low choke method, standpipe pressure method, etc.
