Smart Electric Heating Device for Hollow Sucker Rods

Pass a cable through the hollow sucker rod, creating a circuit with the rod itself. When alternating current is applied, the inner skin effect generates heat directly within the walls of the hollow sucker rod, providing continuous heating to the crude oil inside the tubing. This process raises the temperature of the crude oil, reducing its viscosity and enhancing its flowability. Additionally, it prevents wax deposition inside the tubing, enabling efficient extraction of highly viscous, high-wax-content, and heavy-crude oils—especially those with challenging flow characteristics.

Product Introduction

Pass a cable through the hollow sucker rod, creating a circuit with the rod body. When alternating current is applied, the inner skin effect generates heat directly within the walls of the hollow sucker rod, enabling continuous heating of the crude oil inside the tubing. This process raises the temperature of the crude oil, enhancing its flowability, preventing wax deposition, and ultimately facilitating the efficient extraction of highly viscous, high-wax-content, and heavy-crude oils.

Product Features and Specifications

The production increase has been remarkable. This technology is perfectly suited for heavy oil and high-viscosity oil wells, and as a result of the accelerated pumping strokes, well productivity has improved significantly across the board.

Oil well production efficiency has improved, leading to extended production cycles. Implementing this technology as a complementary solution fundamentally addresses the challenges associated with developing wells producing heavy and highly viscous oils—specifically, ensuring that crude oil can reliably enter the pump barrel allows the well to maintain normal operations. Even after prolonged periods of shutdown, restarting the well becomes remarkably straightforward. This is especially true for ultra-heavy oil steam-injection wells, where this advanced process provides critical technical support during the later stages of production, significantly reducing operational complexity and enabling longer overall well lifespans.

Easy to install and manage, reducing the operational workload for frontline oil workers.

The overall economic benefits are significant. However, there are several challenges: the chemical dosing measures are costly, the thermal cleaning cycle is too short, excessive amounts of chemicals are required, determining the optimal dosing ratio remains difficult, and water injection can easily lead to scaling. Additionally, chemical addition may create difficulties in the dehydration process.
