Oilfield fracturing additives play a vital role in the fracturing process. They are used to meet process requirements and improve fracturing effects. These additives can be divided into multiple categories, mainly including the following:
1. Viscosity agent: Viscosity agent is one of the most important additives in fracturing fluid. Commonly used ones include hydroxyethyl cellulose (HEC), polymers, alginate, etc. They improve the fracturing effect by increasing the viscosity of the fracturing fluid and improving the hydraulic propagation ability of the fracturing fluid in the well.
2. Drag reducer: When the fracturing fluid is sent into the well through a narrow and tortuous well pipe, the addition of drag reducer is indispensable. Common drag reducers include surfactants, silicone oils, and certain polymers with special structures. Drag reducers can reduce the friction and resistance of the fracturing fluid when it is sent into the well, reduce the viscosity of the fracturing fluid, and increase the propagation ability.
3. Proppant: Proppant is a natural sand or artificial high-strength ceramic solid particle with a certain particle size and strength, a certain sphericity and grading. According to the actual application, proppants can be divided into quartz sand proppants, artificial ceramsite proppants and coated proppants, etc. They are used to keep the cracks open after fracturing, thereby increasing oil and gas production.
And oilfield fracturing additives also include degelling agents, corrosion inhibitors, drainage aids, cross-linking agents, clay stabilizers, demulsifiers, foaming agents, fluid loss reducers, pH value control agents, temporary plugging agents, viscosity enhancers, bactericides, etc. These additives each have specific functions and effects, and work together to achieve the best fracturing effect.
Beite Chemical Tips: Please note that due to the continuous development of oilfield fracturing technology, new types and uses of additives may continue to emerge. Therefore, for specific oilfield fracturing operations, appropriate additives should be selected according to specific conditions and process requirements, and relevant safety operating procedures should be followed.
