Problems solved by technology

Therefore, tertiary oil recovery is generally carried out in the petroleum industry, that is, chemical flooding, but the existing oil flooding agents usually only pursue ultra-low section tension, and do not pay attention to the geological characteristics of the reservoir

Abstract

The invention provides a bioenzyme preparation which comprises the following components in percentage by weight: 25-45% of bioenzyme, 9-12% of polyethenoxy ether, 1-5% of sodium hydroxide, 10-15% of sodium silicate, 0.1-0.5% of alkyl glycoside, 1-12% of bis-quaternary ammonium salt and the balance of water. The bioenzyme preparation has the advantages of simple technique, favorable environment-friendly performance and no pollution, effectively enhances the water-injection capability and reduces the friction between the fluid and sandstone, thereby stabilizing the reservoir structure.

Description

Technical field [0001] The present invention relates to the field of biological technology, in particular to a biological enzyme treatment agent. Background technique [0002] At present, in the process of industrial development, such as the process of oilfield development, one-time oil recovery is a process in which crude oil relies on underground pressure and spouts out of the ground through the oil well. With the decrease of the underlying pressure, the spouting process ends. By continuously injecting water into the ground to supplement the underlying energy, the purpose of water flooding is realized. However, with continuous water injection, the water content in the produced fluid continues to rise. Therefore, tertiary oil recovery (ie, chemical flooding) is commonly used in the petroleum industry, but existing oil-displacing agents usually only pursue ultra-low cross-sectional tension and do not pay attention to reservoir geological characteristics.
