High-temperature-resistant and high-pressure-resistant toughened shale gas well cementing cement and preparation method thereof
The invention relates to high-temperature-resistant and high-pressure-resistant toughened shale gas well cementing cement and a preparation method thereof. Relates to the technical field of building materials. Comprising the following components in parts by mass: 68-80 parts of shale gas well cementation cement clinker, 9-15 parts of calcined metakaolin and 3-6 parts of gypsum, and 5-15 parts of an aluminoferrite seed crystal. According to the invention, through deep research on crystal form structures and mechanical properties of different cement clinkers, the crystal form structures and mechanical properties of tetracalcium aluminoferrite in four basic minerals (dicalcium silicate, tricalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite) of the cement clinkers are more in line with the modification on the toughness of set cement. Therefore, a technical thought of improving the Young modulus and toughness of the set cement by increasing the aluminoferrite seed crystal is provided.
一种耐高温高压的增韧型页岩气固井水泥及其制备方法。涉及建筑材料技术领域。包括以下质量份的组分：页岩气固井水泥熟料68‑80份、煅烧后偏高岭土9‑15份和石膏3‑6份；还包括铁铝酸盐晶种5‑15份。本发明通过对不同水泥熟料晶型结构和力学性能的深入研究，在水泥熟料的四种基础矿物中（硅酸二钙、硅酸三钙、铝酸三钙和铁铝酸四钙），铁铝酸四钙的晶型结构和力学性能较符合对水泥石韧性的改造。因此提出了增加铁铝酸盐晶种以改善水泥石杨氏模量和韧性的技术思路。
