1. Project Background:

The National Engineering Laboratory for Exploration and Development of Low-Permeability Oil and Gas Fields requires a four-in-one detection instrument for preventing gas migration in air-foam enhanced oil recovery wells. The gases to be detected are methane, oxygen, carbon dioxide, and nitrogen.

2. Parameter Requirements:

Gas types and measurement ranges:

Methane (CH₄): 0-100% vol, 0.01% vol;

Carbon dioxide (CO₂): 0-100% vol, 0.01% vol;

Oxygen (O₂): 0-25% vol, 0.01% vol;

Nitrogen (N₂): 0-100% vol, 0.01% vol;

High-capacity battery: 15,000 mAh

3. Solution:

Recommended PTM600-4 (CH₄ + O₂ + CO₂ + N₂), with the following parameters:

Methane CH₄: 0-100% vol, 0.01% vol, imported laser TDLAS sensor

Carbon dioxide CO₂: 0-100% vol, 0.01% vol, imported high-precision infrared sensor

Oxygen O₂: 0-25% vol, 0.01% vol, imported industrial-grade electrochemical sensor

Nitrogen N₂: 0-100% vol, 0.01% vol; (calculated value)

The PTM600 is standardly equipped with a battery capacity of 10,800 mAh. According to the customer's special requirements, the supplier has increased the battery capacity inside the detector, with a total battery capacity of 15,000 mAh.
