Abnormal cementing prevention material for well cementing slurry as well as preparation method and application of abnormal cementing prevention material
The invention discloses an abnormal cementing prevention material for well cementation cement slurry as well as a preparation method and application thereof, and relates to the technical field of well cementation materials for oil and gas well engineering. The abnormal cementitious prevention material for the well cementation cement slurry comprises the following components in parts by weight: 40-60 parts of ulexite; 20 to 40 parts of broolerite; 10 to 20 parts of sodium borosilicate; and 5-15 parts of chalcanthite. The abnormal cementing prevention material for the well cementation cement slurry can be used for a myriameter ultra-deep well, is an inorganic material, not only can ensure that the performance is stable and does not lose efficacy in an ultra-high temperature environment, but also is good in adaptability with a cement base material, a high-temperature admixture and an additive, and is wide in application range.
本发明公开了一种固井水泥浆防异常胶凝材料及其制备方法和应用，涉及油气井工程固井材料技术领域。本发明的固井水泥浆防异常胶凝材料，按重量份计，包括钠硼解石40~60份；板硼钙石20~40份；硅硼钠石10~20份；胆矾5~15份。本发明的固井水泥浆防异常胶凝材料可用于万米超深井，是一种无机材料，不仅能够保证在超高温环境下性能稳定不失效，而且与水泥基材、高温外掺料以及外加剂适配性好，应用范围广。
