3 Types of Oil and Gas Well Logging Simulators
Well logging refers to the measurement of geophysical parameters using the electrochemical properties, acoustic properties, conductive properties, radioactivity, and other physical properties of rock formations.
What is Open Hole Well Logging?
During oil drilling, logging should be carried out after drilling to the designed well depth to obtain various petroleum geological and engineering technical data, which are used as the original data for well completion and oilfield development, also known as open hole logging. Open hole well logging is performed when an uncased open hole well is filled with drilling fluid or other fluids. Unless otherwise specified, all newly drilled wells are subject to open-hole well logging.
What is Production Well Logging?
The second series of well logging is performed after the oil well has been casing, also known as production logging or development logging. The development of production logging has generally gone through four stages: analog logging, digital logging, numerical control logging, and imaging logging.
Production well logging is the measurement of flow profiles of fluids in production and injection wells. Measurement parameters include fluid velocity, density, water holdup, temperature, pressure, etc. It is used to understand the nature and flow of fluid produced or sucked in each perforation interval, so as to evaluate the production situation of the oil well and the production characteristics of the oil layer.
The main purpose of production well logging is to evaluate the fluid flow conditions in and out of the oil tubing and the completion of the well.
Features of Production Well Logging
1. Production well logging is well logging performed in a cased hole well.
2. The logging instrument has a small outer diameter, can withstand high temperature and high pressure, and has strong corrosion resistance.
3. The well logging speed is slow.
4. It is mainly carried out in the way of spot measurement and continuous measurement.
What is a Production Well Logging Simulator?
The production well logging simulator conducts pre-job training and skill assessment for logging technicians and workers by using logging theory, virtual reality technology, computer technology, multimedia technology, etc.
What are the training programs?
1. Operation training for wellhead workers
The training items include wellhead test valve or non-test valve tubing injecting operation, wellhead test valve or non-test valve casing injection operation, and wellhead test valve or non-test valve oil pumping operation.
2. Operation training for winch workers
Training items include normal descent, normal ascent, obstacle descent, and obstacle ascent.
3. Operator operation training
Training programs include five-parameter comprehensive logging, oxygen activation logging, impedance logging, audio logging, caliper logging, electromagnetic flow logging, single magnetic orientation logging, and pre-magnetic orientation logging.
What is an Open Hole Well Logging Simulator?
The open hole well logging simulator has the same operating consoles and panels as the real equipment. By using 3D technology to demonstrate the structure and working principle of logging equipment, the entire process from logging preparation to completion. And through the combination of live scenes and live sound effects synchronized with the operation, a real training environment is created.
What are the training programs?
1. Training programs for wellhead workers
Including wellhead equipment installation, bridle production, the connection of logging tools, casing injection operation without test valve at the wellhead, cut-threak freeing and fishing, equipment disassembly, etc.
2. Winchman’s training program
Includes normally raising, normally lowering, etc.
3. Various animations
Various logging methods are included: conventional resistivity logging, lateral logging, spontaneous potential logging, microresistivity logging, acoustic logging, gamma-ray logging, induced well-logging, density logging, open hole diameter logging, neutron logging, etc.
Introduction to various logging operations and maintenance: introduction to basic logging material, maintenance of logging wellhead equipment, making and maintenance of bridle, basic operation and maintenance of surface unit, working principle and maintenance of basic downhole logging tools, the technology of cable perforation, the technology of tubing conveyed perforation, the technology of open hole logging and horizontal well logging. These various operational animations are used for the learning and training of technicians and workers.
There are other training programs available, you can contact Esimtech to learn more.
What is a Composite Well Logging Simulator?
The whole process of composite logging is introduced by using advanced logging software, a full-scale logging machine room designed by Esimtech, a sand table well site model, drilling accident modeling software, and sensor detection software. Composite logging simulators are used to train operators, training center logging staff, and petroleum academies. Through the training of this system, the trainees can master various operational skills to deal with drilling accidents.
What are the training programs?
1. Tripping in operation
Including lost circulation when tripping out, kick when tripping out, oil or water immersion when tripping in, kick when tripping in, blowout when tripping in, getting blocked when tripping in, stuck pipe when tripping in, nozzle plugged, and abnormal standpipe pressure.
2. Monitoring circulation and static state
Including lost circulation, oil or water immersion, overflow, kick, and blowout.
3. Accidents when drilling and reaming
Including bit service life end, bit wore out, drilling string broken, lost circulation, well immersion, overflow, drill pipe not well braked, percussion drilling, lost nozzle, stuck pipe, wall collapse, pump water feeding failure, high-pressure pipe leaking.
4. H2S detection
Including formation H2S and non-formation H2S.
5. Monitoring formation pressure
6. Damper failure
