Application of Petroleum Equipment Processing Components

The application of petroleum equipment processing components runs through the entire industry chain of petroleum exploration, drilling, oil extraction, and gathering and transportation. The core is suitable for harsh working conditions such as high temperature, high pressure, strong corrosion, and high wear. The core components and application scenarios of different links are as follows:

1. Exploration and drilling process: withstand the impact of extreme working conditions

Drill pipe/drill collar components: including joints, stabilizers, etc., often made of high-strength alloys or titanium alloys, need to withstand high pressure, torque, and friction for several kilometers underground to ensure stable power transmission during drilling and resist mud corrosion.

Drill bits and accessories: The tooth crown of the roller drill bit and the cutting tooth seat of the PDC drill bit are processed with hard alloy or wear-resistant coating, suitable for crushing operations in different formations (sandstone, granite, etc.), requiring high hardness and impact resistance.

Drilling fluid circulation components, such as mud pump cylinder liners and valve bodies, are made of corrosion-resistant and wear-resistant alloys, which can withstand the erosion and corrosion of drilling fluid (including sand, acidic and alkaline media), ensuring smooth circulation of drilling fluid and maintaining downhole pressure balance.

2. Oil extraction and downhole operations: ensuring long-term stable production

The core components of the pumping unit include crankshafts, connecting rods, and donkey head pins, which require high-strength and fatigue resistant processing to withstand repeated mechanical loads and adapt to long-term continuous operation on land and sea platforms.

Underground tool components: The rubber cylinder seat of the packer and the slip of the oil pipe anchor are made of corrosion-resistant alloy and can be reliably sealed in high-temperature (up to 150 ℃ or above) and high-pressure environments underground to prevent oil and gas leakage.

Electric submersible pump components: impeller, shaft sleeve, etc., ensure dynamic balance through precision machining, and have oil and gas resistance and sand erosion resistance, suitable for deep well and high viscosity crude oil extraction, and improve oil recovery efficiency.

3. Gathering and refining process: resist medium corrosion and wear

Pipelines and connectors: Flanges, elbows, and valves of oil pipelines are processed with corrosion-resistant alloys (such as duplex steel and nickel based alloys) to resist corrosive media such as hydrogen sulfide and carbon dioxide in crude oil and natural gas, and avoid leakage risks.

Refining equipment components: heat exchanger tube bundles, reactor internals, requiring high temperature resistance (up to 500 ℃), high pressure resistance, and corrosion resistance. Precise machining is used to ensure sealing performance and heat transfer efficiency, and is suitable for refining processes such as crude oil cracking and hydrogenation.

Core components of the pump valve: the impeller of the centrifugal pump and the valve seat of the ball valve are made of wear-resistant and corrosion-resistant materials, which can withstand the erosion of impurities in crude oil, reduce wear and failure, and ensure the continuous operation of the gathering and transportation system.

4. Exclusive components for offshore oil equipment: adapted to the special marine environment

Platform structural components: conduit frame, pile leg connectors, processed with high-strength seawater corrosion-resistant alloy to resist ocean salt spray and tidal impact, while lightweight design reduces the platform's load-bearing capacity.

Underwater production system components: underwater wellhead connectors, umbilical cable joints, requiring extreme corrosion resistance and sealing performance, stable operation in deep-sea high-pressure and low-temperature environments, and remote control of underwater oil and gas extraction.
