portable dosing system for adding anticoagulant in oil fields

Its simple design and mobility make it ideal for multi-point operations at oilfield sites and in field environments. In addition, the device’s independent power supply design facilitates its operation in remote areas.

Oilfield anticoagulants are widely used in gas well fracturing operations, which mainly have two important roles:

1. Reducing the construction friction resistance of the freeze gel: during the construction process, the addition of anticoagulant can reduce the construction friction resistance of the freeze gel and improve the fluidity of the fracturing fluid in the underground pipeline. This helps to improve construction efficiency and makes the construction process smoother, reducing the risk of pipeline blockage.
2. Improve sand-carrying performance: anticoagulants can improve the sand-carrying performance of the gel, ensuring that the fracturing fluid can effectively carry and transport sand particles under high-pressure operating conditions. This is very critical for sand stabilization in gas well fracturing operations and enhancing the inflow capacity of formation fractures.
3. Increase the formation energy of the return fluid: anticoagulant can enhance the formation energy by reducing the vaporized water density in the return fluid, which can help the smooth return of the fracturing fluid and improve the production and recovery efficiency of the oil and gas wells.

The structural design of the portable dosing system is centered on high efficiency and convenience, and usually includes the following main components:

1. Solution tank: used to store oilfield anticoagulant solution, ensure the supply of anticoagulant and ensure that the dosing system can work continuously and stably.
2. Metering pump: to precisely control the dosing amount of anticoagulant and ensure that it is mixed with the fracturing fluid in a predetermined proportion to achieve the best construction effect.
3. Filter: used to filter the impurities in the solution, avoiding the anticoagulant from being clogged or damaged in the process of using the equipment.
4. Safety valve: to ensure the safety of the equipment in the process of use, to prevent excessive pressure from damaging the system.
5. Check valve: prevent the solution from flowing back to ensure the working stability of the dosing system and the unidirectionality of the liquid flow.
6. Pulse damper: smooth pressure fluctuations in the system, to ensure that the anticoagulant delivery process is smooth and fluid.
7. Water level meter: used for real-time monitoring of the water level in the solution tank, to avoid running out of solution leading to equipment shutdown.
8. Control cabinet: integrated control system, through which the operator regulates and monitors the work of the whole dosing system.
9. Base: all the equipment is integrated in a solid base to ensure the stability and durability of the system.
10. Wheels and front axle steering system: the device is equipped with four wheels and front axle steering system, which is convenient for moving and hauling in the oil field site, improving the flexibility and convenience of the device.
11. Diesel generator and electronic control system: the device is specially equipped with a diesel generator and an independent electronic control system, so that it can run independently in the field operation, to ensure that the equipment can still work stably without external power supply.
