Choosing the right downhole pump is one of the most critical decisions in oilfield production. A mismatch between the pump type and well conditions can lead to frequent workovers, lost production, and skyrocketing maintenance costs.
As a high-volume lifting solution, the API Tubing Pump is the industry standard for efficiency. But with various configurations like TH and TP, and countless material options, how do you ensure you are making the right investment?
In this guide, we will break down everything you need to know to select the perfect pump, maximize your run life, and leverage factory-direct customization.
1. The Core Choice: TH vs. TP Tubing Pumps
The most fundamental decision is selecting the barrel configuration. While both are API 11AX compliant, they serve very different environments.
Technical Comparison Table
| Feature | TH (Heavy Wall) | TP (Thin Wall) |
| Barrel Type | Thick-walled, stationary barrel | Thin-walled, high-volume barrel |
| Mechanical Strength | Superior; resists high pressure | Moderate; focuses on bore size |
| Max Depth | Suitable for deep wells (>8,000 ft) | Shallow to medium wells (<6,000 ft) |
| Main Advantage | Durability & resistance to deformation | Maximized fluid production (BPD) |
| Best Application | High-pressure, harsh environments | High-volume wells with standard pressure |
Our Recommendation: If you are operating in deep or high-pressure reservoirs, the API TH Tubing Pump is the safest and most cost-effective long-term choice due to its structural integrity.
2. Metallurgy & Customization: Beyond the Standard
At DongSheng Rod Pump, we understand that no two oil wells are identical. While we strictly follow API 11AX standards, our strong customization capabilities allow us to tailor the metallurgy to your specific downhole challenges.
Material Selection for Harsh Conditions:
For Abrasive/Sandy Wells: We recommend a Spray Metal Plunger combined with a Chrome-plated Carbon Steel Barrel. This combination provides a hard-wearing surface that resists scoring from sand particles.
For Corrosive Environments (H2S/CO2): Standard steel will fail. We offer Monel or Stainless Steel components and specialized coatings to prevent stress corrosion cracking.
For High-Viscosity/Heavy Oil: We can customize the Fit Tolerance (e.g., increasing clearance to .004" or .005") to reduce friction and ensure the plunger moves smoothly through heavy crude.
3. The 3-Step Selection Logic: An Engineering Approach
To minimize your bounce rate and maximize efficiency, follow our engineers' 3-step logic before placing an order:
Step 1: Define Your Production Target
Calculate your target Barrels Per Day (BPD). If volume is the priority and the well is shallow, a larger bore TP pump might be necessary. If reliability in a deep well is the goal, choose TH.
Step 2: Analyze the Fluid Profile
Is there gas interference? Is there a high sand cut? This will determine if you need additional accessories like a gas anchor or a long-plunger sand-control design.
Step 3: Verify the Tubing Size
Ensure the pump's outer diameter (OD) is compatible with your existing tubing string. Our TH pumps are designed for seamless integration with standard API tubing sizes.
