High-temperature well cementation cement as well as preparation method and application thereof
The invention relates to high-temperature well cementation cement as well as a preparation method and application thereof. The high-temperature well cementation cement comprises the following raw materials in percentage by mass: 69-72% of cement raw material and 28-31% of quartz sand; wherein the cement raw material is composed of G-grade oil well cement and nuclear power cement in a mass ratio of4:6 to 5:5. The well cementation cement provided by the invention is relatively long and stable in thickening time, basically does not decline in strength along with temperature rise, and is particularly suitable for well cementation engineering in Africa.
本发明涉及一种高温固井水泥及其制备方法和应用,所述高温固井水泥含有如下质量百分比的原料:水泥原料69‑72%;石英砂28‑31%;所述水泥原料由质量比为4:6‑5:5的G级油井水泥和核电水泥组成。本发明所述的固井水泥,其稠化时间较长且稳定,强度随着温度升高基本不衰退,尤其是适用于非洲地区的固井工程。
