| titleOfInvention | The molten sulfonated gilsonite of drilling fluid peracid |
| abstract | The invention discloses the process of the molten sulfonated gilsonite of drilling fluid peracid：Light oil is added in a kettle, then add the pitch powder of lightweight weight of oil 40 50%, it is heated to 30 50 DEG C, first add the liquid sulphur trioxide for accounting for liquid sulphur trioxide total amount 60~70%, add shepardite micro mist, rosin and aluminum stearate, it is sufficiently stirred to obtain mixed solution, the sodium hydroxide solution of pitch weight 30 40% is added in mixed solution again, with alkali neutralization and adjust pH value, when the molten thing content of oil is less than 30%, again in reaction kettle addition liquid sulphur trioxide, light oil is recycled, is baked to and crushing obtains the molten sulfonated gilsonite of peracid.The present invention can form thin and compact mud cake when boring and opening oil reservoir, and shielded layer is formed in the thin layer of rock of borehole, can effectively control the number of dropouts of drilling fluid, improve mud cake intensity, prevent rock stratum water suction from peeling off；On the other hand protection reservoir, makes reservoir permeability be restored and improve. |
