摘要:

在油田化学领域,通过研选合适的疏水材料对井壁或储层岩石表面进行润湿性改造,可以减弱表面对水相的亲和性,从而达到抑制岩石水化、减少储层水相圈闭及改善储层油气渗流能力等目的,极大提高油气田的开发效益。本文简要介绍了疏水材料的种类并分析了疏水材料形成憎水性表面的原理,重点从稳定井壁、保护储层、提高油气采收率和改善乳液及泡沫稳定性四个关键方面阐述了疏水材料在油田化学领域中的研究进展。针对于目前存在的不足,展望了疏水材料作为一种油田化学助剂,未来应向着低成本、强配伍、多功能、环境友好型方向发展,以满足其在油田化学领域中不断增长的需求。

Abstract:

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.

Key words: hydrophobic materials, hydrophilic property, wettability modification, hydrophobic mechanism, oilfield chemistry
