Application of Drilling and Well Sinking of Oil and Natural Gas
Sodium carboxymethyl cellulose Application of Drilling and Well Sinking of Oil and Natural Gas
In drilling and well sinking projects of oil and natural gas, the wellbore in the deep well is apt to water loss, leading to hole shrinkage and collapse phenomena. Then the drilling machine will be impeded and it will affect the smooth advance of the project, even leading to a failure halfway. Therefore, the drilling mud must be prepared with appropriate quantitative values such as density, viscosity, thixotropy and water loss to guarantee the smooth operation of drilling machine.
However, the above-mentioned parameters of drilling mud vary with such conditions as the area, well depth and mud type. The addition of Sodium carboxymethyl cellulose cmc into the mud can adjust these physical parameters and make polyanionic cellulose more suitable for the need of project.
