In recent years, Southwest Oil & Gas has independently developed bottom-hole purification reagents in response to the bottom-hole pollution problem of tight sandstone gas reservoirs in western Sichuan, and continuously optimized bottom-hole purification technology to effectively help stabilize the production of old wells.

Tight sandstone gas reservoirs in western Sichuan have the characteristics of low porosity, low permeability, strong heterogeneity, high capillary force, and high water saturation.

To clean the bottom of the well, pollution diagnosis is the basis.

In response to the bottom-hole pollution diagnosis and analysis results, the institute developed three sets of bottom-hole purification "secret recipes.

To successfully purify the bottom of the well, the "medicine" method is essential.
