Shengli Oilfield develops 10,000-ton level biosurfactant production technology

Sinopec News Network reported that after nearly 10 years of hard work, Shengli Oilfield broke through the core technical bottleneck, developed a complete set of 10,000-ton biosurfactant production technology, and launched large-scale applications on site, with a cumulative oil increase of 268,000 tons
.

Oil-displacing agents with surfactants as the main body play a vital role in the development process of oilfields such as enhanced oil recovery.
Biosurfactants, as a class of surfactants produced by microbial fermentation, are green, low-cost, and temperature-resistant.
The advantages of salt, etc.
, are becoming larger and larger in oilfield applications
.
In accordance with Sinopec's requirements for creating a clean energy company and green and high-quality development of oil fields, it is imperative to develop green and low-cost oil-displacing agents

The newly developed biosurfactant is based on synthetic biotechnology and constructed multiple genetically engineered strains.

In view of the contradictions in the development of water flooding reservoirs, medium and low permeability reservoirs and heavy oil reservoirs, researchers have also constructed lipopeptide ultra-low interfacial tension, rhamnolipid wetting and drag reduction, and modified sophorolipid emulsification to reduce viscosity.

This technology facilitates the upgrading and development of oilfield enhanced oil recovery technologies, accelerates the advancement of green and low-cost oil production preparations, and contributes important technical forces to the creation of green ecological oilfields
