FRACTURING AGENT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a fracturing agent composition capable of carrying out the fracturing safely in a short time. SOLUTION: This fracturing agent composition consisting essentially of an expansive clinker consisting essentially of quick lime and a self hardening material contains hard granules having <=0.5 wt.% moisture content. Preferably, the composition comprises 50-88 wt.% expansive clinker, 2-10 wt.% self hardening material and 10-40 wt.% hard granules. The hard granules are nonreactive inorganic granules having >=200 kgf/cm2 compressive strengths and having 0.3-10 mm particle diameters.
