Description
Technical Field
The utility model relates to an oil field technical field, very special be an oil field comprehensive operation waste liquid, extraction water sled dress portable treatment device.
Background
The refractory waste liquid in the development process of oil and gas fields mainly comprises drilling waste liquid, fracturing flow-back liquid, complex-containing surfactant waste liquid for cleaning oil pipes and oil tanks, polymer-containing waste liquid for tertiary oil recovery, acidified well washing waste liquid, heavy oil produced water, high-salinity oil field produced water and the like, wherein the complex-containing surfactant for cleaning the fracturing flow-back liquid, the oil pipes and the oil tanks is taken as an example, the waste liquid is mainly characterized in that the viscosity of an oil-containing high-molecular polymer is high, the stability of colloid particles in water is strong, and natural degradation is not easy; the waste liquid has high oil content and strong emulsification stability, and oil and water are not easy to separate; belongs to high-difficulty waste water with high oil content, high COD, high turbidity and high mineralization.
Aiming at the difficult-to-degrade waste liquid, the conventional oil removal-air flotation-filtration treatment process is difficult to reach the standard of reinjection, recycling and discharge. Therefore, researchers propose a new treatment method, for example, patent CN 101993177B discloses a treatment method of polymer-containing sewage in oil field, which comprises subjecting the polymer-containing sewage to aerobic degradation by microorganism and then to post-stage filtration treatment; patent CN 103043833 a discloses an electrochemical method for polymer-containing sewage treatment in oil field, which comprises the following steps: performing electric flocculation on the polymer-containing sewage of the oil field to be treated; carrying out oil-water separation on the polymer-containing sewage subjected to electric flocculation to obtain a water phase; then filtering the water phase to realize viscosity reduction of polymer-containing sewage in the oil field; patent CN 103011363B discloses a method for treating polymer-containing sewage in oil field, which comprises the following steps: adding block polyether, nonionic surfactant and ethanol into the polymer-containing sewage of the oil field, and then uniformly mixing to remove oil and purify water of the polymer-containing sewage of the oil field; patent CN 203513352U discloses an ozone air flotation device for treating polymer flooding oily sewage; patent CN 202542914U discloses a sewage preprocessor and sewage preprocessor device, including: a water pipe and an ultrasonic vibration device; patent CN 1686851a discloses a new method for treating oil field sewage, which uses iron in water as oxidation catalyst and coagulant, hydrogen peroxide as preoxidant, and active silicic acid series as coagulant aid. However, these methods also have difficulty in meeting practical production requirements.
The method which is widely applied and has obvious treatment effect is a medicament formula innovation at present, and has great effect on treating the difficult-to-degrade waste liquid. Although some chemicals effectively separate oil and water and remove harmful substances when treating waste liquid, safety problems and side effects are also caused, for example, conventional chemical agents are added into an oil-gas field in the pretreatment process of the waste liquid: although the strong acid, the strong base and the hydrogen peroxide can obviously reduce the viscosity of the waste liquid, ensure subsequent coagulation and precipitation and effectively purify the waste liquid through equipment, the two waste liquids belong to dangerous chemical agents, particularly sulfuric acid, not only have adverse effects on a medicine adding person, but also easily cause safety accidents; in the face of the treatment of waste liquid at a remote wellhead, the transportation is inconvenient; when the dosage of the strong acid is not tightly controlled, equipment corrosion is easily caused. In addition, the commonly used composite formula flocculating agent, coagulant aid and other agents in the oil and gas field can effectively separate suspended matters, oil and the like in the waste liquid, but the conventional separator is configured, such as walnut shell filtration or quartz sand filtration and other equipment, so that the separated harmful substances easily block the filler, and the equipment cleaning and filler replacement frequency is increased; a large amount of chemical agents are required to be added for treating the high-difficulty waste liquid, so that the amount of sludge generated is large, and the subsequent sludge is difficult to treat; when the dosage of the medicament is not properly controlled, certain ions in the water body are increased, and the secondary recycling and reinjection of the waste liquid are directly influenced.
