Regulator for deep liquid flow of oil reservoir and preparation method and application of regulator

The invention provides a regulator for a deep liquid flow of an oil reservoir and a preparation method and application of the regulator. The regulator for the deep liquid flow of the oil reservoir comprises the following raw materials: a slug I and a slug II in a volume ratio of (25-40):(60-75), wherein the slug I contains the following raw materials: coco-betaine amide propyl betaine, cocamide propyl lauryl hydroxysultaine, pectin, an amide modified starch copolymer YX-I, sodium chloride, sodium polyacrylate, phenol, thiourea and the balance of water; and the slug II contains the following raw materials: high pour-point oil, kieselguhr, white carbon black, lime milk, polyvinyl alcohol, an epoxy resin, tetraethylenepentamine, silica gel powder and the balance of water. The invention further provides a preparation method of the regulator. When being applied to plugging of a deep part of a medium/deep oil reservoir injection and production well, the regulator is good in thermal stabilityand high in slug intensi
