Description
Technical field
The present invention relates to fracturing propping agents and preparation method thereof, relate in particular to and utilize standby fracturing propping agents of magnesium ore deposit mine tailing, iron ore mine, boric sludge and preparation method thereof.
Background technology
Pressure break refers in oil recovery or gas production process, utilizes hydraulic action, makes hydrocarbon zone form a kind of method in crack.Hydrocarbon zone fracturing technology process fracturing truck, the liquid that high-pressure large-displacement is had to certain viscosity is clamp-oned oil reservoir, after oil reservoir is extruded to many cracks, add propping agent (as quartz sand etc.) filling to enter crack, improve the penetrating power of hydrocarbon zone, to increase water injection rate (water injection well) or oil offtake (oil well).Fracturing Technology plays an important role in the exploitation of oil, Sweet natural gas, and the effect of pressure break depends on the technical feature of fracturing propping agents largely.
After when propping agent is waterfrac treatment, stratum presses off crack, be used for supporting crack not make crack closed a kind of solid particulate again.In use propping agent is sneaked in fracturing liquid, utilize high pressure tactics to inject the deep layer rock fracture and support rock stratum, to improve the Oil Guide rate, increase the purpose of crude production rate.Therefore propping agent is the critical material of pressing crack construction.For guaranteeing effectively strutting of underground deep layer pressure-break, must select suitable propping agent.
Sintering ceramsite, because intensity is high, degree of sphericity is good, is the preferential fracturing propping agents of selecting of people.Traditional ceramsite propping agent is that to take bauxitic clay and flint clay be raw material, and by the powder granulation, high temperature sintering forms, finished product in conjunction with being high-strength corundum-mullite phase mutually, as CN1085288A, the disclosed propping agent of CN101787270A.But, along with China's mine resources develops on a large scale, the not only price increase amplitude of main raw material bauxitic clay that traditional method is manufactured haydite is large, and the bauxitic clay resource is also day by day nervous.Therefore, find cheap effective alternative raw material production high-strength ceramic granule propping agent is one of pursuing a goal of this area always.
When forsterite-cordierite porcelain comprises that when its crystalline phase forsterite accounts for 26-60%, trichroite and accounts for content that 10-28%, enstatite account for 0.5-5%, forsterite and be greater than the content of trichroite, this porcelain has the advantages that thermal shock is stablized, physical strength is high, experimental results show that the requirement that utilizes ceramsite propping agent that this combination is produced mutually can meet oil fracturing technique.Our country contains abundant wagnerite, boron stone, iron ore resource, but along with for many years continuous exploitation has been saved bit by bit a large amount of industrial tailings as boron mud, iron ore mine, magnesium ore deposit mine tailing etc., the discharge of these industrial tailings has not only taken a large amount of farmlands and mountain region, and become environmental pollution source, cause the phenomenon of the vicious cycle such as the reasonable utilization ratio of mine resources is low, development of resources expense height.How utilizing the discarded industrial tailings such as boron mud, iron ore mine, magnesium ore deposit mine tailing to produce stay-in-grade ceramsite propping agent, is the work meant a great.
