Description

Technical Field

[0001] The utility model relates to the technical field of puffing devices, in particular to a starch puffing device for drilling fluid. Background Art

[0002] Drilling fluid is a general term for various circulating fluids that meet the needs of drilling work with their multiple functions during the drilling process. It is mainly composed of liquid phase, solid phase and chemical treatment agent. Drilling fluid can penetrate into the formation, resulting in a certain amount of filtration loss. When there are low-solubility calcium ions and sodium ions, in order to control the filtration loss, adding starch can play a good role. In order to better control the filtration loss, starch needs to be added to the drilling fluid. In order to better promote the role of starch, the starch needs to be pre-treated by expansion.
