As a branch of mechanics, fluid mechanics plays an inestimable role in human daily life and survival, but various seemingly simple phenomena in life contain the most common principles in fluid mechanics knowledge. In oil exploitation and transportation, fluid mechanics is the most important framework of various technical means, especially seepage mechanics and pipeline design (resistance calculation).

The process of fluid mechanics learning: Advanced Mathematics (Upper and Lower), the first and second volumes must be completely learned; Then "vector analysis and field theory"; Then, Engineering Fluid Mechanics; Then there is "viscous fluid mechanics". For petroleum, we should also learn "non-Newtonian fluid mechanics" and "seepage mechanics". You can't just read advanced mathematics. It takes a certain amount of exercises to master.

Oil is stored underground, so people want to use it, first of all, they need to extract it, and then transport it to a specific place through pipelines for steaming, fractionation, chemical processing and so on. In the exploitation and transportation of oil, every breakthrough and innovation has an unbreakable relationship with fluid mechanics. In oil exploitation, seepage, a branch of fluid mechanics, shines brilliantly; In oil transportation, pipeline design calculation based on fluid mechanics also plays an inestimable role. Therefore, for petroleum engineering, the focus of fluid mechanics is "seepage mechanics" and "engineering fluid mechanics".
