High-temperature-resistant oil well cement retarder and preparation method thereof
The invention relates to the technical field of oil wells, and provides a high-temperature-resistant oil well cement retarder and a preparation method thereof.The high-temperature-resistant oil well cement retarder is prepared from, by weight, 25-35 parts of hydroxy carboxylate, 8-14 parts of inorganic salt, 3-12 parts of 5, 6-diamino-1, 10-phenanthroline, 5-7 parts of sodium p-styrenesulfonate, 3-16 parts of palmitamide and 90 parts of water. By means of the technical scheme, the problems that in the prior art, an oil well cement retarder is poor in retarding effect at the high temperature, thickening time is unreasonably regulated and controlled, and oil well cement is poor in compressive strength are solved.
本发明涉及油井技术领域，提出了一种耐高温油井水泥缓凝剂及其制备方法，耐高温油井水泥缓凝剂包括以下重量份的组分：羟基羧酸盐25~35份、无机盐8~14份、5,6‑二氨基‑1,10‑邻菲罗啉3~12份、对苯乙烯磺酸钠5~7份、棕榈酰胺3~16份、水90份。通过上述技术方案，解决了相关技术中油井水泥缓凝剂高温下缓凝效果差、稠化时间调控不合理、油井水泥抗压强度差的问题。
