This invention relates to the field of oilfield chemistry, and discloses a betaine compound, its preparation method, and its application. The betaine compound has the structure shown in Formula I: In Formula I, m = 1-30; n = 1-15; R1 is a C1-C8 carbon chain alcohol or a C6-C8 aromatic alcohol; R2 and R3 are each independently hydrogen or methyl; R4 is a C1-C3 alkylene or hydroxylated alkylene; M ‑ SO3 ‑ or COO ‑ The betaine compound contains a large number of PO groups, increasing the size of the hydrophobic groups. Betaine percolators containing this compound, through the synergistic effect of the PO groups and betaine molecules, transform the active components of crude oil into low-molecular-weight components (such as fatty acids), reducing the interfacial film strength of the betaine and thus improving the deformability of the emulsion. The betaine compound of this invention can be used as a betaine percolator for fracturing in low-permeability reservoirs, further improving oil recovery.

The present application relates to a kind of high-efficiency industrial water treatment cleaning agent and its preparation method, belong to water treatment reagent technical field.The present application is by synthesizing the cashew phenol grafting male pinoate sulfonic acid sodium compound containing isomeric decanol polyoxyethylene 7 ether segment, cashew phenol segment and sulfonic acid group simultaneously, and cashew phenol grafting male pinoate sulfonic acid sodium compound, nitrilo tris (methylene phosphonic acid) trisodium salt, 1-isopropoxy-2-propanol, 2-amino-1-butanol and ethanol are physically compounded, to obtain cleaning agent;Cashew phenol grafting male pinoate sulfonic acid sodium compound contains nonionic surfactant segment and anionic sulfonate group simultaneously, and both synergistic cooperation, jointly improve surface activity, oil removal capacity, and long alkane hydrophobic chain segment, olefin segment and benzene ring in cleaning agent can be adsorbed on metal surface by hydrophobic interaction and conjugation, and negatively charged sulfonic acid sodium can repel corrosive negative ion, reduce the corrosion to metal.
