Embodiment 1
[0038] This embodiment provides a broad-spectrum chlorine-free coagulation accelerator accelerator for cement used in oilfield well cementing, which is prepared by the following steps:
[0039] Weigh 1 part by weight of sodium fluorosilicate, 1 part by weight of calcium aluminate, 1 part by weight of aluminum sulfate, and 1 part by weight of metakaolin, and pour them into a mixing device and mix them uniformly to obtain the early strength agent.
[0040] This embodiment also provides a kind of cement slurry that is used for oil field well cementing, and it is prepared through the following steps:
[0041] Take by weighing 700g grade G oilfield cement, 21g early strength agent (accounting for 3.0% of cement quality), 17.5g fluid loss reducer DRF-300S, 4.2g dispersant DRS-1S and 301g water, the above components Mix to make cement slurry.
