Novel integration technique for improving recovery ratio of thick oil with high thickness and low yield

The invention provides a novel integration technique for improving a recovery ratio of thick oil with high thickness and low yield. The technique comprises the following steps of: extracting the thick oil: preparing a thick oil dispersing drag reducer into 1 percent aqueous solution serving as a sample a and 0.125 percent aqueous solution serving as a sample b, mixing 1,900-2,500 milligrams/liter of sample a and 230-280 milligrams/liter of sample b uniformly, and injecting the mixture in a well by using a casing, mixing medicaments on the pump with the thick oil to form an oil-in-water emulsion, lifting the emulsion to the mouth of the well by an oil pumping unit, and feeding the emulsion in an oil-water separating tank through a pipeline; breaking the emulsion and separating water from oil: adding a corresponding amount of efficient thick oil demulsifier continuously to prepare 1 percent aqueous solution while the thick oil enters the oil-water separating tank, wherein the adding amount is 90-110 milligrams/liter, and the reaction time is more than 2 hours, namely, oil-water separated sewage is to be treated; treating and recycling the sewage: pumping the sewage in the tank, adding a special coagulant to prepare 2 percent solution, wherein the adding amount is 80-120 milligrams/liter, adding a composite anti-incrustation corrosion inhibitor simultaneously to prepare 2 percent aqueous solution, wherein the adding amount is 48-53 milligrams/liter; adding a DL-328 industrial sterilant to prepare 5 percent aqueous solution, wherein the adding amount is 85-115 milligrams/liter, and blending with clear water, and injecting in the stratum to retain the pressure balance of the stratum.
