"Why Oil Drilling Needs Sodium Carboxymethyl Cellulose CMC"

The matter of oil drilling is related to the energy of the country, the foundation of people's livelihood, and is of paramount importance. People at Hanhua Chemical Production Plant often think about one thing, that is, why oil drilling needs sodium carboxymethyl cellulose CMC. Try to solve it today.

The place where oil drilling is located is mostly complex and difficult, and the underground geological conditions are ever-changing and unpredictable. When drilling, the drill bit needs to go thousands of meters deep into the ground, which is difficult to achieve if only by ordinary methods. The key lies in the drilling fluid.

Sodium carboxymethyl cellulose CMC has many wonderful uses in drilling fluid. First, it can increase the viscosity of the drilling fluid. If the viscosity of the drilling fluid is appropriate, it can effectively carry the drill cuttings. The drill bit breaks the rock underground, and the drill cuttings generated will accumulate at the bottom of the well if they cannot be brought out of the wellhead in time, which will affect the drill bit's continued drilling and may even damage the drill bit. CMC increases the viscosity of the drilling fluid, acting as a powerful arm, steadily lifting the drill cuttings and bringing them to the surface to ensure the smooth progress of drilling work.

Second, it can reduce the filtration loss. During the drilling process, the formation pressure around the well wall is different from the drilling fluid pressure, and the water in the drilling fluid is easy to penetrate into the formation. If there is too much water loss, the performance of the drilling fluid will change, which will affect the drilling effect. CMC can form a dense protective film on the well wall, which acts as a solid barrier to prevent water seepage, maintain the stability of drilling fluid performance, and ensure smooth drilling.

Third, help stabilize the well wall. Underground rock structure, or loose, or fragile. When drilling, if the well wall is unstable, it is easy to collapse, resulting in drilling accidents. CMC can improve the rheology of drilling fluid, so that the drilling fluid is evenly distributed around the well wall, forming a supporting force, strengthening the well wall, ensuring its stability, and avoiding the risk of collapse.

Furthermore, CMC is lubricating. The drill bit rotates at high speed underground and rubs heavily against the well wall. Friction generates heat, which not only loses the drill bit, but also affects the drilling efficiency. CMC can form a lubricating layer between the drill bit and the well wall, which is like a lubricant, reduces friction, reduces the loss of the drill bit, increases the drilling efficiency, and saves man-hours and costs.

To sum up, in the complex and difficult work of oil drilling, sodium carboxymethyl cellulose CMC has become an indispensable thing with its wonderful effects of increasing viscosity, reducing filtration loss, stabilizing the well wall, and lubricating. Everyone at Hanhua Chemical Production Plant knows its importance and studies it carefully to ensure that the products are excellent and add to the oil drilling industry, so as to ensure the smooth exploitation of energy and help the prosperity of the country and the prosperity of the people.
