OIL And Gas Drilling Rig Draw works-Master Course

Study sprockets, chains, and their tooth profiles, and how their arrangement affects power and speed in machine systems.

Explore how an air clutch uses compressed air to engage and disengage power between the engine and transmission, and compare jar-type and friction-type clutches.

Explore how a lubrication pump on oil and gas rigs operates as an electrical pump with spray lubrication oil, and how foam pressure gauge in the drill console supports monitoring.

Explore hydraulic disc brake systems on the drawing drum, featuring multiple calipers and independent actuation, with emergency and parking brake functions replacing band brakes.

Activate the emergency brake to stop the drilling rig during main brake failure, engaging all six calipers and the safety caliper while addressing wear, hydraulic issues, and debris.

This lecture explains the disc brake system on a drill rig draw works, including the hydraulic unit, control panel, drum and service and safety calipers, plus parking and emergency brakes.

Identify and diagnose disc brake troubleshooting by examining hydraulic pressure issues, oil quality and level, leakage, valve settings, pump performance, temperature, filter blockage, and misalignment affecting caliper release.

Examine how the auxiliary brake supports the main service brake to slow and control loads, prevent overheating, and extend brake life on a drilling rig.

Compare the service brake and auxiliary brake on drilling rig draw works; service brake controls operation, auxiliary brake handles heavy loads, with air or water as power.

Discusses factors affecting brake life, including air cooling ventilation, lubrication and maintenance, brake clearance, and monitoring water level and pump pressure for water cooling.

Explain brake cooling systems for drilling rigs, including water cooling with inhibitors and antifreeze, and three methods—water cooling, air cooling, and solid surface cooling—for sustaining cooling cycles and brake performance.

Learn how pneumatic ground systems operate automatically to control the crown saver, using air valves to engage or disengage the clutch, move the traveling block, and apply emergency brakes.

Learn how to set the pneumatic ground system, engage the emergency brake on contact with the rolling line, and reset to release using the main brake and reset button.

Learn to set the electric ground server with lower and upper limits, position the elevator and traveling block, and safely release the emergency brake after turning on the main breaker.

Explore the components of drilling lines, including wire, strands, core, and lubrication, and how these form a wire rope used in oil and gas drilling.

Discover wire rope lay concepts, including strand direction and right versus left lay, and how regular and Langley patterns govern strand alignment along the rope axis.

Investigate strand patterns in wire rope design, covering single and multi-layer arrangements, center cores, wire diameters, filler wires in valleys, and combined strand configurations.

Classify wire rope by outer strands and wires per strand, illustrating configurations such as six by nineteen and six by twenty-one with ranges from three to fourteen wires per strand.

Properly clamp and tighten the drilling line on the draw drum, pass the line through a passage on one side of the driver, and secure it at the drum end.

Highlight the advantages of air over hydraulic fluid. Emphasize air's abundant supply, easy storage and transport, temperature insensitivity, safety, cleanliness, and fast expansion for high speed operation at low cost.

Analyze atmospheric constituents such as nitrogen, oxygen, carbon dioxide, water vapor, and other gases, and explain how contaminant-free compressed air supports efficient pneumatic system operation and longer component life.

Air contaminants raise pressure losses and disrupt the pneumatic system, delaying response times and compromising control, leading to expensive downtime.

Filtration removes particles that can damage the air compressor, followed by drying to reduce humidity between the compressor and receiver. Air treatment removes moisture and adds oil mist for lubrication.

Explore air applications on drilling rigs, including starting engines with power packs, lifting tubulars on the rig floor, and operating control panels and wellhead installations.

Visualize the general application of the pneumatic system on drilling rigs, highlighting power, process, and control applications such as starting up the engine and the BP control panel.

Explore the hydraulic system on a drilling rig, featuring the hydraulic tank, high-pressure pump, motor control center, and its role in draw work and BP operation.

Explore what gears are and how gears and sprockets connect to transmit drive and speed, distinguishing driving and driven gears and noting brass sprockets.

Explore two gas system types: step down gears and step up gears. Step down lowers output speed with a smaller gate and larger circumference, while step up increases output speed.

Master the chain drive torque and speed formula by examining driver and driven sprockets, teeth counts, and the inverse relationship between speed and gear teeth, with a worked example.

Explore the relation between power and speed, showing how they can be inversely proportional. Demonstrate calculating total power divided by speed to illustrate their interaction.

Examine a chain drive drawworks transmission case study, calculating input and output rpm across low, intermediate, and high gears using sprockets and chain connections.

The lecture covers daily, monthly, semiannual, annual, and five-year inspections aligned with API recommended practice, defining category 1 through 3 inspections for drawworks components.

Perform routine inspections and ongoing maintenance of drone systems to enhance efficiency and safety, extend component life, and prevent incidents and costly downtime.
