OIL AND GAS FIELD CHEMICALS. |
摘要 |
<p>This invention relates to a process for increasing the effectiveness of production chemicals by reducing the number of squeezing and shut-in operations needed to increase the production rate from an oil well. The process comprises injecting into an oil-bearing rock formation a water-miscible formulation comprising as components: (a) a water-miscible surfactant which is an alkyltriglycol ether and (b) at least one water-miscible oil field or gas field production chemical, said components of the formulation being introduced either as a pre-formed single composition, or simultaneously in parallel or sequentially in either order into the rock formation via the production well.</p> |
