SG-ZY oil and cold oil

SG-ZY cold collector molecular system is a large molecular weight with a branched three-dimensional structure of the surfactant. Mainly to solve the following oil field mining problems:

    1, High viscosity of crude oil, poor rheology, high starting pressure, resulting in heavy oil development: "wells do not inject, the oil can not take."

    2, Water flow ratio than large. Conventional waterflooding development, due to high viscosity of crude oil, formation seepage resistance increases, resulting in high pressure injection wells, the corresponding wells are not effective.

    3, Many old blocks or fracturing transformation blocks, reservoirs exist high permeability strip, due to oil and water flow ratio is large, easy to cause injection into the water, the formation of water channeling, resulting in flooding flooding.

    Features:   

    1, Soluble in water, liquid and crude oil with "miscible" performance, so that crude oil dispersion, thereby reducing the viscosity of crude oil.

    2, Increase the viscosity of oil and liquid interface, liquid liquid flow, drag the crude oil flow, increase water flooding efficiency.

    3, Can dissolve heavy components, improve seepage capacity, improve the mining effect.

    4, Temperature, high degree of high salinity.

    5, In the core mineral static adsorption capacity is low.

   Process characteristics:  

1, injection wells flooding injection process

The process is to dilute the oil-cooled cold water to 600PPM concentration, with the injection of water from the injection wells into the formation, injection of large amount of liquid, long construction period (usually 3-5 months), the effect of oil after construction significantly , Valid for a long period of time.

2, Single well cold stimulation throughput construction process

     The process is a certain amount of oil-cooled cold preparation formulated into 1-2% concentration (the general liquid 600-1000m3), with the cement vehicle by the measures of the one-time injection into the treatment layer. The process construction time is short, quick, yield effect is obvious, but the validity period is shorter.

3, Single well casing dosing process

The process is to dilute the liquid (2% concentration), periodically quantitatively from the casing into the well. The construction of the process is simple and effective.
