【摘要】 煤层气水力压裂过程中会向煤层中注入大量压裂液和各种添加剂,从而会对煤岩性质产生影响。本文从煤岩的表面化学性质出发,研究不同类型压裂液和添加剂在不同条件下对煤层颗粒表面化学性质的影响,揭示外加离子对煤层颗粒迁移的影响规律,明确煤粉运移控制机理,探索合理的煤层气排采制度。
【Abstract】 During coalbed methane(CBM) wells hydraulic fracturing,large amount of fracturing fluid and various addictives are injected into coal seams,the coal surface physicochemical properties will be impacted by these fluids.In this paper,based on the coal surface chemical properties,the impact of different types of surfactant and various additives on coal particles surface chemical properties under different conditions were investigated, the impact of applied ions on the coal particles migration and the migration mechanism was studied,and reasonable CBM drainage systems were explored.
【Key words】 coalbed methane； surface chemical properties； surfactant； particle migration；
