Four HWMPS50 model twin-screw multiphase pump skids, tailor-made for 41 oil wells in Xinjiang Oilfield (including 9 reserved wells to be commissioned), precisely match the local harsh operating conditions—1. Overview: Tailored for Xinjiang Oilfield’s Needs
Four HWMPS50 twin-screw multiphase pump skids are made for 41 oil wells in Xinjiang Oilfield. This includes 9 reserved wells to be commissioned.
They fit local harsh conditions: high gas content, high water cut, and extreme low temperatures. They cover all needs—from condition adaptation to installation and maintenance. And they act as core equipment for efficient oil-gas transportation.
2. Condition Adaptation: Matching On-Site Requirements
2.1 Medium & Temperature Fit
Xinjiang Oilfield media include oil, gas, water and sand. The operating temperature is 30-50℃. The environment can drop to -35℃.
The pump skids are built to handle these tough conditions.
2.2 Flow & Pressure Performance
The 4-unit parallel design works well for on-site demands. Each unit has a rated liquid flow of 100 m³/h.
It handles current liquid needs (2480 t/d) and end-of-year needs (1650 t/d). It also adapts to maximum gas volume (≤25000 Nm³/d).
Even at 95% gas volume fraction (GVF), the pumps run stably. This solves high-gas transportation issues.
2.3 Pipeline Compatibility
Inlet pressure is 0.25-0.3 MPa. Outlet pressure is 1.6 MPa. Maximum pressure difference is 1.4 MPa.
This matches the on-site DN200 pipelines. No extra modifications are needed for quick commissioning.
3. Core Configuration: Reliable & Durable
3.1 Wear & Corrosion Resistance
The pump body is welded with 20# steel. It has a forced circulation return valve. It also has reserved anti-corrosion allowance.
Shaft and screw sleeve are made of integrally forged 42CrMo steel. Their surfaces get sand-resistant and anti-corrosion treatment.
Bushing is welded with 20# steel. Its inner hole has sand-resistant treatment. This fights sand-induced wear.
3.2 Safety & Brand Components
Bearings are from SKF/NSK. Seals are double mechanical seals with PLAN54 flushing.
The 75KW motor has DIIBT4 explosion-proof class. This ensures safety in flammable oilfield environments.
4. Supply & Factory Acceptance: Hassle-Free Deployment
4.1 Skid-Mounted Supply
Each pump skid integrates parts onto one base. These parts include the multiphase pump, motor, and 25L flushing oil station. It also has a 20-mesh basket filter (8x flow capacity).
It is supplied as a complete skid. No on-site disassembly or assembly is needed.
4.2 Spare Parts & Accessories
Full sets of accessories are included. These are anchor bolts, matching flanges, and gaskets.
Free spare parts are also provided: 1 mechanical seal set, 1 bearing set, 1 oil seal set, and 1 special tool set.
4.3 Strict Factory Tests
Before delivery, all units pass two key tests:
- Rated displacement liquid measurement (meets flow demands).
- GVF 95% gas measurement (stable temperature rise).
This ensures every unit meets design standards.
5. On-Site Advantages: Energy-Saving & Practical
The pumps use 380V/3PH/50HZ power. This fits on-site power supply.
The operating frequency is around 40 Hz. This is economical and controls energy use.
For Xinjiang Oilfield’s complex conditions, these pumps support continuous, efficient, and low-cost production.
