  • Characteristics:

    Environmentally friendly, 100% biodegradable, and the production process is green and environmentally friendly.

    Excellent surface activity and low critical micelle concentration.                                      

    Under high temperature and high salt conditions, it can still maintain good chemical stability.                       

    Promote the proliferation of geological microorganisms and indirectly increase the oil recovery rate


    Experimental data and materials:

    The crude oil viscosity of this well is 3546mPa. s, with low liquid volume (2t/d) and low oil volume (0.8t/d). In May 2015, the bio surfactant BS composite throughput was implemented. After construction, the daily liquid production remained stable at around 10 tons for the first 3 months, but decreased to around 5 tons in the later period. The daily oil production increased from 1.4 tons to around 3 tons, and the water content decreased from 80% to 44%. So far, it has been effective for nearly 9 months, with an increase in oil production exceeding 520 tons. Before the implementation of the well, the liquid level was low and frequent hot washing was required to maintain production. The hot washing cycle was one month. Since the implementation of the bio surfactant BS composite throughput, only one hot washing was done on December 11th, effectively reducing the frequency of hot washing. At present, the liquid level is 876m and the energy is sufficient.
