Application of Oil-based Drilling Fluid Sealing System in Oilfield Development
With the growing global demand for energy,oilfield development has become a focal point in the international energy landscape.Oil-based drilling fluids play a crucial role,and their sealing system is vital for the safe and efficient operation of oil well drilling.This paper focuses on the sealing system of oil-based drilling fluids,introducing the trends in global energy demand and the technological challenges faced in oil well drilling.The fundamental principles of oil-based drilling fluids,including their composition,core principles of blocking leakage pathways,and increasing fluid viscosity,are detailed.The selection principles and interaction mechanisms of additives and colloidal particles are discussed.Through practical case studies,the successful application of the sealing system of oil-based drilling fluids in oil well sealing repair and drilling fluid optimization is demonstrated.The system effectively addresses wellhead leakage issues,reduces liquid leakage risks,and enhances drilling efficiency.
