AU-18 Agent for Increasing Heavy Oil Production

Details:

<p> <span style="font-size: 16px"><strong>AU-18 Agent fIncreasing Heavy Oil Production </strong></span></p> <p> Crude oil in the resin asphaltene content increased, on its viscosity, mobility variation, to the mining brought many difficulties over the years, crude oil extraction have been using thermal recovery method the emulsion viscosity reduction method, made some effect, but the thermal recovery method investment in infrastructure is too large, the microscopic short-term benefits, emulsion viscosity reduction method in the application of single well on a smaller scale, emulsion-breaking more difficult economic benefits were not evident. We have extensive access to domestic international data, based on the development of a synthetic polymer-based heavy oil production agent, It can reduce the oil viscosity pour point, has a certain ability to drive oil, salt resistance, the indofield tests proved that the increase of oil has good effects.</p> <p> <br /> <strong>Specification:</strong><br /> (1) Appearance: Black liquid;<br /> (2) PH value (1% solution): 8 ~ 11;<br /> (3) Solubility: completely dispersed in water;<br /> (4) Density: 0.90 ~ 1.05g/cm3;<br /> (5) improve the chemical flooding oil recovery: 10 to 15%;<br /> (6) heavy oil viscosity reduction rate: ≥ 90%</p> <p> <br /> <strong>The mechanism of action:</strong><br /> (1) reduce the oil-water interfacial tension, formation water to keep moist, thus reducing the oil flow resistance, to improve oil flow;<br /> (2) make heavy oil to form O / W type emulsion, reducing its viscosity;<br /> (3) changes in resin asphaltene molecular structure to break down fthe short-chain material, reducing its pour point viscosity.</p> <p> <br /> <strong>Usage:</strong><br /> (1) the principle of well-made<br /> ①the size of crude acid 1mg / l of crude oil<br /> ②formation of residual oil saturation> 60%<br /> ③formation water calcium magnesium ions ≤ 350mg / l<br /> ④formation clay content <8%<br /> (2) on-site construction<br /> ①Preparation of 2% with water heavy oil production agent<br /> ②Press the amount calculated radius of 2.0 ~ 3.0mm<br /> ③backwashing with water wells 1 to 2 weeks<br /> ④good yield with a pump will be prepared to squeeze into the strata agent, shut-18h after the open wells.</p>
