Calcium silicate/gelatin grafted sulfonated aldehyde ketone nano-seed crystal early strength agent for deepwater/ultra-deepwater low-temperature well cementation and preparation of calcium silicate/gelatin grafted sulfonated aldehyde ketone nano-seed crystal early strength agent
The invention discloses a hydrated calcium silicate/gelatin grafted sulfonated aldehyde ketone nanocrystalline early strength agent for deepwater/ultra-deepwater low-temperature well cementation and a preparation method of the hydrated calcium silicate/gelatin grafted sulfonated aldehyde ketone nanocrystalline early strength agent. The preparation method comprises the following steps: synthesizing gelatin grafted sulfonated aldehyde ketone polycondensate; and preparing the hydrated calcium silicate/gelatin grafted sulfonated aldehyde ketone nano seed crystal early strength agent through a precipitation method by taking the gelatin grafted sulfonated aldehyde ketone polycondensate as a dispersion phase. The structural formula of the gelatin grafted sulfonated aldehyde ketone polycondensate is shown in the specification. The use temperature range of the hydrated calcium silicate/sulfonated aldehyde ketone nano composite seed crystal early strength agent for oil well cement provided by the invention is 2-60 DEG C, when the addition amount of the hydrated calcium silicate/sulfonated aldehyde ketone nano composite seed crystal early strength agent in cement paste is 0.5-4.0% of the mass fraction of cement, the early strength agent has an obvious early strength effect, and the improvement of the hydrated later strength is obviously higher than that of the existing common hydrated calcium silicate seed crystal material. # imgabs0 #
本发明公开了深水/超深水低温固井用水化硅酸钙/明胶接枝磺化醛酮纳米晶种早强剂及其制备。所述制备包括合成明胶接枝磺化醛酮缩聚物；以明胶接枝磺化醛酮缩聚物为分散相通过沉淀法制备水化硅酸钙/明胶接枝磺化醛酮纳米晶种早强剂。所述明胶接枝磺化醛酮缩聚物其结构式如下所示。本发明提供的油井水泥用水化硅酸钙/磺化醛酮纳米复合晶种早强剂使用温度范围为2～60℃，在水泥浆中的加量为水泥质量分数的0.5～4.0％时，均有明显的早强效果，对于水化后期强度的提升明显高于现有普通纳米水化硅酸钙晶种材料。#imgabs0#
