  The present application provides an aqueous fluid containing a gas-generating compound such as an azo compound, a hydrazide compound, or a semicarbazide compound. The aqueous fluid may also contain an amine compound, an oxidizer, or viscosifier, and a foaming surfactant. The aqueous composition may be storable at pH of less than about 5 without any appreciable gas generation, and may be activated to produce gas when mixed with a wellbore fluid for use in downhole applications.

  本申请提供了一种含气化合物（如偶氮化合物、酰肼化合物或半咔嗪化合物）的水基流体。该水性流体还可含有胺化合物、氧化剂或增粘剂以及发泡表面活性剂。水性组合物在 pH 值小于 5 时可储存，不会产生明显的气体，当与井筒流体混合用于井下应用时，可活化产生气体。

  The present application provides a gas-generating aqueous fluid containing a gas-generating compound like an azo compound, and an organic amine like a primary, secondary or tertiary amine, a hydrazine, a hydrazide, or a semicarbazide. The aqueous fluid may also a viscosifier, and a foaming surfactant. The present application also provides a method of using the gas-generating composition to modulate density of a wellbore fluid for use in downhole applications. The method optionally includes adding an oxidizer to the wellbore fluid.
