Oil well cement paste containing elastic particles
The invention relates to the technical field of oil well cement, and discloses oil well cement paste containing elastic particles, which is prepared from the following components in parts by weight: 65 to 70 parts of oil well cement, 7 to 10 parts of concrete fiber, 2 to 5 parts of early strength agent, 2 to 3 parts of sodium silicate, 1 to 4 parts of anti-freezing agent and the balance of water. 6.5-7 parts of anhydrous sulfate and a proper amount of UF500 cellulose fiber are doped into the oil well cement, and the concrete fiber contains carbon fiber, glass fiber, polypropylene fiber and steel fiber which are mixed according to the ratio of 2: 1: 1: 2. In a low-temperature environment, the early strength agent, sodium silicate and oil well cement are fused, the setting time of the cement can be shortened, silica fume and superfine mineral powder are doped in the early strength agent, the early strength and the later strength can be greatly improved, the water content in cement paste is reduced through doped anhydrous sulfate, the cement paste is prevented from being frozen, and concrete fibers and elastic particles are added, so that the early strength and the later strength are improved. And the material can be well bridged at the crack.
本发明涉及油井水泥技术领域,且公开了一种含有弹性粒子的油井水泥浆,包括以下重量份的组分:油井水泥65份‑70份、混凝土纤维7份‑10份、早强剂2份‑5份、泡花碱2份‑3份、防冻剂1份‑4份、余量为水,早强剂中掺和硅灰和超细矿粉,油井水泥中掺入6.5份‑7份的无水硫酸盐、适量的UF500纤维素纤维,混凝土纤维中含有碳纤维、玻璃纤维、聚丙烯纤维和钢纤维,且四者按照2:1:1:2混合而成;在气温低环境中,早强剂、泡花碱与油井水泥融合,能够将水泥的凝固时间缩短,并且早强剂中掺和硅灰和超细矿粉能够大幅度提高早期和后期强度,掺加的无水硫酸盐减小水泥浆中水含量,避免水泥浆受冻,加入混凝土纤维和弹性粒子,可以较好的跨接在裂缝处。
