Abstract

The invention relates to the field of blocking removers, in particular to a blocking remover based on a fluorocarbon surfactant micelle structure and a preparation method of the blocking remover. Theblocking remover based on a fluorocarbon surfactant micelle structure comprises the following components in parts by weight: 0.1-1.5 parts of a fluorocarbon surfactant, 4-20 parts of composite acid and the balance of deionized water, totaling 100 parts. The fluorocarbon surfactant in the blocking remover provided by the invention is good in compatibility, the interfacial tension of oil and water is relatively low, organic and inorganic impurities can be effectively stripped, the production amount of crude oil is relatively high, and the blocking remover is particularly suitable for productionof low-permeability oil and gas fields.

Description

technical field

[0001] The invention relates to the field of plugging agents, more specifically, the invention relates to a plugging agent based on a fluorocarbon surfactant micelle structure and a preparation method thereof. Background technique

[0002] Petroleum is a strategic material related to the lifeline of my country's economy. In my country, the development and production stabilization technology of medium and high permeability reservoirs is relatively mature. Yield and economic benefits are a major challenge faced by many domestic oil fields. Therefore, how to improve the level of tertiary oil recovery technology and increase the recovery rate of existing oil reservoirs has important economic value and strategic significance.

[0003] In the process of oilfield exploitation, the oil layer will be blocked due to various reasons in the production process, resulting in a decrease in permeability and production. In order to ensure the normal production of the oilfiel...
