Description
Technical Field
The invention belongs to the technical field of oilfield chemical drilling fluid treating agents, and particularly relates to a sulfonated amino alkyl glycoside lubricant and a preparation method and application thereof.
Background
In recent years, with more and more difficult wells such as deep wells, ultra-deep wells, long horizontal section horizontal wells, extended reach wells and the like, the requirement on drilling fluid lubrication anti-sticking is higher and higher. In the early stage, mineral oil such as crude oil, diesel oil, white oil and the like is mixed in the drilling fluid to better meet the requirement of underground lubrication and anti-sticking, but the application of mineral oil lubricants is limited along with the increasing strictness of environmental protection requirements, so that the research and development of green and environment-friendly high-performance lubricants become a main development trend. Certain work is carried out on vegetable oil ester and animal fat lubricants at home and abroad, the product types are more, but the performance of the lubricant cannot well meet the lubrication requirements of high-difficulty wells such as long horizontal section horizontal wells and high-temperature high-density drilling fluids at present.
Disclosure of Invention
In view of the above, the invention aims to provide a sulfonated amino alkyl glycoside lubricant for drilling fluid, and a preparation method and application thereof.
The invention provides a sulfonated amino alkyl glycoside lubricant for drilling fluid, which has a structure shown in formula I:
in the formula I, m is 1-5, preferably 1-3;
n is 1 to 7, preferably 1 to 5;
o is 1 to 7, preferably 1 to 5;
R1is an alkyl group having 4 to 9 carbon atoms, preferably-C4H9、-C6H13、-C8H17、-C10H21or-C12H25；
R2Is an alkylene group having 1 to 3 carbon atoms, preferably-CH2-or-C2H4-；
M is Na, K or NH4。
The sulfonated amino alkyl glycoside lubricant for the drilling fluid has a specific structure, and the lubricant with the specific structure has a good lubricating effect. In addition, the sulfonated amino alkyl glycoside lubricant for the drilling fluid provided by the invention has no biotoxicity. The sulfonated amino alkyl glycoside lubricant for the drilling fluid can be applied to the drilling fluid, is suitable for the drilling construction of a shale oil-gas horizontal well long horizontal section and a high-temperature high-density drilling fluid, meets the requirement of drilling fluid lubrication anti-sticking control, and realizes green, safe and efficient drilling.
The invention provides a preparation method of a sulfonated amino alkyl glycoside lubricant for drilling fluid, which comprises the following steps:
