| 摘要 |
The present invention consists of a water-based inhibited perforation fluid composition which is essentially composed of fertilizers for agriculture such as it is the potassium nitrate and sodium silicate. Its employment is directed in the perforation of oil wells or gas extraction in soils with lutitic clays content, acting as neutralizing agents of hydration, property supplied by potassium, without the need of increasing the chlorides. The complete water-based inhibited perforation fluid composition achieves to obtain viscosity, well wall stability, suppression of the filtrating invasion, inhibition, lubricity, density, sheeting and utilization of the perforation fluid, and the well wall springs as fertilizers for soils in agriculture.
