摘要： Improved methods of drilling well bores utilizing foamed aqueous drilling fluids are provided. The methods basically comprise circulating an aqueous drilling fluid containing a single foaming and defoaming surfactant and a gas downwardly through a rotary drill pipe and drill bit connected thereto. Well bore cuttings generated by the drill bit are lifted to the surface by foam produced from the aqueous drilling fluid and gas. Upon reaching the surface, the foamed aqueous drilling fluid is defoamed whereby the cuttings and gas are removed therefrom and the aqueous drilling fluid is combined with additional foaming surfactant when needed and additional gas. The foaming and defoaming of the aqueous drilling fluid are accomplished by changing the pH of the aqueous drilling fluid from basic to acidic which causes the single foaming and defoaming surfactant to foam and defoam the aqueous drilling fluid.

摘要： The present invention provides a process for forming cement in a well bore. In this process, a cement composition is formed that comprises a cement and one or more beads mixed with the cement. The cement composition containing the beads is displaced into the well bore, and an inert gas phase is introduced to the cement composition to control a density of the cement composition. The inert gas phase can be introduced by adding a gas generating material to the cement composition and/or a porous material to the cement composition. In an embodiment, the gas generating material is a nitrogen generating material that may be activated by an oxidizing agent. In another embodiment, the gas generating material is a hydrogen generating material, e.g., an aluminum powder. The present invention further provides a cement composition comprising a cement, one or more beads combined with the cement, and an inert gas phase created by, e.g., a gas generating material and/or a porous material.
