Recovery Process
Electric heating + CCUS
The Challenge
High viscosity, high-deviation wear and extreme power consumption — multiple bottlenecks constraining CCUS heavy oil development
High Viscosity, Pump Entry Difficulty
Comprehensive water cut of 89%, sand content of 0.3%, and degassed crude dynamic viscosity of 8,031 mPa·s. Wellbore temperature fluctuates with fluid supply; at low temperatures, crude viscosity rises, making pump entry difficult and production volumes low.
High-Deviation Wear, Short Cycles
Constrained by 66° well deviation, severe rod-tubing wear leads to short pump inspection cycles and frequent maintenance.
Extreme Power Consumption, Low Heat Utilization
Electric heating-assisted rod pumping results in extremely high power consumption and operating costs. Unable to switch injection-production without pulling tubing, leading to low thermal utilization.
The Solution
HXBS deployed the IntelliCPCP® Intelligent Tapered Progressing Cavity Pump System
A combined hardware-software approach that comprehensively upgrades the lifting process, targeting the multiple production bottlenecks under CCUS and electric heating conditions.
Leverages the superior adaptability of progressing cavity pumps for heavy oil, significantly reducing electric heating usage and energy consumption. Also enables injection-production integration without pulling the tubing string.
Supports remote monitoring and automatic parameter tuning (e.g. auto pump efficiency adjustment); highly integrated surface facilities with a small footprint significantly reduce daily maintenance frequency.
