Research progress and prospects of hydrophobic materials in oilfield chemistry
In the field of oilfield chemistry,the application of hydrophobic materials has achieved remarkable results.The wettability modification of the wellbore wall or reservoir rock surface by suitable hydrophobic materials can weaken the affinity of the surface for the aqueous phase.This method can effectively inhibit the hydration of rocks,reduce the aqueous phase trapping of reservoirs and improve the seepage capacity of oil and gas in the reservoirs,which greatly improves the development benefits of oil and gas fields.In this paper,the types of hydrophobic materials were briefly introduced and the mechanism of hydrophobic materials to form hydrophobic surfaces was analyzed.The research progress of hydrophobic materials in the field of oilfield chemistry was described from four essential aspects:stabilizing the wellbore,protecting the reservoir,enhancing oil and gas recovery,and improving the stability of emulsions and foams.Given the current deficiencies of hydrophobic materials as a kind of oilfield chemical additives,the future development of hydrophobic materials should be toward the direction of low cost,strong compatibility,multi-functionality and environment-friendly to achieve the increasing demand in the field of oilfield chemistry.
