The invention relates to the field of oil and gas well cementation, and discloses an oil well cementation cement slurry system and application thereof. The cement paste system comprises the following components in parts by weight: 100 parts of oil well cement, 20-80 parts of a high-temperature stabilizer, 15-80 parts of a high-temperature reinforcing agent, 0.5-6 parts of a retarder, 2-10 parts of a fluid loss agent, 0.1-2 parts of a defoaming agent and 35-90 parts of water, wherein the high-temperature stabilizer is a mixture containing quartz sand, silica fume and nano-silica which are different in average particle size; the high-temperature reinforcing agent is selected from at least one of pyrophyllite, epidote, actinolite, aluminum stone, sillimanite and boehmite. The cement paste system is mixed by adopting a conventional method, the density and the thickening time are adjustable, the flowing property is good, the water loss is small, the strength of formed cement stone is high, the cement stone does not decline for a long time at the high temperature of 150-240 DEG C, and the technical requirements of deep and ultra-deep high-temperature and high-pressure well cementation construction are completely met.

This invention relates to the field of rotary calcining furnace technology, and in particular to a special integrated calcining and quenching furnace and processing technology for seven calcinations and eight quenchings of actinolite, to solve the problem that existing calcining devices are not suitable for rapid quenching. The device includes a rotary furnace mechanism, a quenching mechanism connected to one side of the rotary furnace mechanism, and a conveying mechanism disposed inside the rotary furnace mechanism. The conveying mechanism includes a ring chain that drives inside the rotary furnace mechanism, and multiple calcining cylinders are slidably connected within a limiting ring. The side walls of the calcining cylinders are provided with mesh holes. The conveying mechanism also includes a pad, the part of the pad inside the rotary furnace mechanism being flat and the part outside the rotary furnace mechanism being concave. The concave surface of the pad and two arc-shaped baffles together form a quenching tank. The quenching mechanism supplies quenching decoction to the quenching tank. The process includes adding an eighth calcination modification after the traditional seven calcinations and seven quenchings, thereby changing the medicinal properties of actinolite. This invention can rapidly quench calcined actinolite.
