Abstract:
     This invention is an improvement of the composition of water-base pressure cleavage liquor used in petraleum production. Inorganic Zr-compound can cross-link to a very food viscoelastic Zr-gel in alkaline or acidic medium. Such Zr-gel pressure cleavage liquor is high viscous, low frictional and residueless after breaking down. Inorganic Zr-compounds are anti-swelling agent for clay. This liquor can be used in high clay-containing strata, and is inexpensive, easily obtainable. Its production cast is 18-35% less than that of boron-gel liguor at the same anti-friction level.
