| 摘要 |
The present invention refers to the preparation of foaming formulations for supporting high temperatures, salinity and divalent ion concentrations such as calcium and magnesium, which provide the synergic effect of sodium alpha olefin sulfonate and alkyl amido propyl betaine; said formulations may use water, sea-water, and congenital water and alcohols as a solvent, or a mixture thereof. The formulations control the gas supply in naturally fractured wells of the carbonated type.
