Description
Technical Field
The invention relates to the technical field of synthetic oil, in particular to biomass synthetic oil for well drilling and a preparation method thereof.
Background
The base oil is the main component for preparing the drilling fluid, and the performance indexes of the base oil determine the vast majority of performance indexes of the drilling fluid, such as flash point, viscosity, freezing point, biological toxicity and the like. Along with the increasing number of deep well, ultra-deep well, horizontal well and large-slope directional well encountered by drilling, the probability of drilling in a strong water-sensitive stratum is higher and higher, and the synthetic base drilling fluid is widely applied due to excellent lubricating, inhibiting and other properties. However, the base oil used for preparing the synthetic base drilling fluid at present is mainly chemical products such as mineral oil, olefin, alkylbenzene, linear paraffin and the like, has the defects of certain toxicity and poor biodegradability, and has been limited to be applied to some environment sensitive areas. With the increasingly strict national environmental protection requirements, the development of environment-friendly drilling fluid and green drilling fluid base oil become the main directions of research and application in the field.
Therefore, there is a need for a biodegradable base oil with good drilling fluid performance indexes such as inhibitive performance, viscosity, temperature resistance, and hydrolytic stability.
