Product Introduction
An oil pumping unit (also known as a pumping unit) is the core surface equipment in the oil extraction process. It is mainly used to lift crude oil from the underground formation to the surface, and is an indispensable production equipment for conventional oilfields, low-yield wells and various special working condition oilfields (such as deserts and alpine regions). Its core function is to drive the downhole oil pump to do reciprocating or rotating motion through the transmission of surface power, so as to realize the continuous extraction of crude oil.
Types and Characteristics of Equipment
Type
Beam Pumping Unit:Application Scenarios: Conventional oil wells, low-yield wells and medium-shallow wells, especially suitable for oilfields with moderate crude oil viscosity and low sand content, and it is the main equipment for global conventional oilfield exploitation.
Features
Features: Core Features: Simple structure, strong reliability, low manufacturing cost and easy maintenance, no need for complex control systems, suitable for harsh environments such as the field, desert and alpine regions; stable operation, low failure rate, low later maintenance cost, and suitable for long-term continuous operation.
Oil pumping unit
An oil pumping unit is a key machine used to lift crude oil from oil wells to the surface.
Oil pumping unit
It is commonly known as a "nodding donkey" and provides power for artificial oil lifting.
Basic Principles and System Composition
Basic Working Principle
As the core surface equipment for oil extraction, the oil pumping unit operates following the core logic of "power transmission - downhole linkage - crude oil lifting". Its system composition is divided into three modules (surface, downhole and intermediate connection) around this logic. All modules work together to realize the continuous extraction of crude oil from the downhole to the surface. The basic principle and system composition are detailed below.
Overall System Composition
Surface Part (Core of Power Output) Core components: Motor (mainly energy-saving frequency conversion type), Reduction Gearbox (reducing speed and increasing torque), Crank-Connecting Rod-Beam Mechanism (motion conversion), Horsehead & Polished Rod Eye (connection and transmission), Control System (start/stop, speed regulation, monitoring).
Downhole Part (Core of Crude Oil Lifting) Core components: Oil Pump (core for oil suction and discharge), Pump Barrel & Plunger (forming pressure difference), Screen Pipe (filtering impurities and protecting the pump).
Intermediate Connection Part (Bridge for Transmission and Transportation) Core components: Sucker Rod (transmitting power), Oil Pipe (transporting crude oil and preventing leakage).
Basic Principles and System Composition
Preliminary Preparation: Inspect wellhead, circuit, motor and downhole equipment Start-up Operation: The motor drives the oil extractor, driving the sucker rod anddownhole pump for reciprocating oil extraction Crude Oil Gathering and Transportation: Wellhead oil output - Metering Station - Oil-Water Separation - Qualified crude oil external transportation Daily Maintenance: Inspect equipment, monitor parameters, analyze faults Pump Inspection and Well Repair: Shut down when faulty, replace damaged components,and put into production again.
