Fracturing cement slurry of self-generated heat-conducting permeable stone and application thereof
The invention discloses fracturing cement slurry of self-generated heat-conducting permeable stone and application thereof. The fracturing cement slurry of the self-generated heat-conducting permeablestone is prepared from 5-30 wt% of a heat-conducting agent, 10-40 wt% of a penetrating agent, 20-50 wt% of cement and 20-60 wt% of water. After the fracturing cement slurry is pressed into natural pore cracks and artificial cracks of a stratum, hydration, thickening, tackifying, automatic temporary plugging, steering, crack forming, crack expanding and crack extending are conducted continuously,and a three-dimensional fracture network is formed; and after the fracturing cement slurry is solidified, the self-generated heat-conducting permeable stone with high heat conductivity, high permeability, high strength, large fracture surface and micro-nano-scale communicating apertures is formed, and supports and communicates with the three-dimensional fracture network. The fracturing cement slurry can be widely applied to the fields of fracturing production increase, thermal recovery, heat conduction, heat exchange, water control, sand prevention, collapse prevention, leakage prevention, corrosion prevention and the like of exploitation of coal bed gas, shale gas, shale oil, combustible ice, terrestrial heat, thickened oil and other unconventional energy sources.
本发明公开了一种自生导热渗透石的压裂水泥浆及应用，该自生导热渗透石的压裂水泥浆由导热剂5‑30wt％，渗透剂10‑40wt％，水泥20‑50wt％，水20‑60wt％配制而成。该压裂水泥浆被压入地层天然孔隙裂缝和压开人工裂缝后，不断水化、稠化、增粘，自动暂堵、转向、造缝、扩缝、延缝，形成立体裂缝网；压裂水泥浆凝固后，成为具有高导热、高渗透、高强度、大缝面和微纳米级连通孔缝的自生导热渗透石，支撑和连通立体裂缝网。本发明可广泛应用于煤层气、页岩气、页岩油、可燃冰、地热、稠油等非常规能源开采的压裂增产、热采、导热、换热、控水、防砂、防塌、防漏、防腐等领域。
