August 7, Jilin Oilfield self-developed microbial membrane oily wastewater treatment technology in the application of 10 months after the successful adoption of sewage injection water quality testing. This technology will ensure the quality of wastewater injected into the formation and provide strong technical support for the development of "enough water, good water, fine water injection and effective water injection" for low permeability oilfields.
"This sewage treatment technology is very good, the application of 10 months time, the quality of our plant wastewater backwater injection in the company ranked first!" August 7, at the Xinmin Oil Production Plant in Jilin Oil Field Processing Station, engineering technician Lu Bright and happy to say. Let Lu Mingliang full of praise is independently developed by Jilin Oilfield microbial membrane oily wastewater treatment technology.
Jilin Oilfield has entered the middle and high water cut-off period. Once the oilfield water has passed the treatment, it is reinjected into the underground for reinjection. Sewage injection plays an important role in the continuous stable production in the oilfield and in protecting the ecological environment. With the development of waterflooding of low permeability oil reservoir in oilfield, the requirements on effluent quality of reinjection stratum become more and more strict. Using qualified and less contaminated wastewater to inject back into the formation can not only supplement the formation energy effectively and ensure the smooth production of crude oil, On the conservation of water resources and environmental protection are very important.
The so-called microbial membrane oily wastewater treatment technology is the combination of microbial treatment technology and membrane separation technology, in the oily wastewater by adding a specific combination of specific bacteria to provide suitable growth environment water. Through the competition with microorganisms in sewage, the dominant microflora is formed. Using hydration, activation and oxidation, the complex organic matters such as sludge are degraded into simple inorganic substances. The final products are water and carbon dioxide, so as to purify sewage.
Over the years, Jilin Oilfield has been focusing on re-injection of sewage compliance rate, microbial membrane treatment technology has ushered in a qualitative leap in water quality compliance rate. According to Lu Mingliang introduction, Jilin Oilfield explicitly requested that the injection of sewage oil content per liter shall not exceed 10 mg, suspended solids should not exceed 5 mg per liter. Through the application of the technology, the treated sewage can be controlled at less than 2 milligrams per liter for the equipment outlet and less than 1 milligram per liter for the treated sewage. At the injection pump inlet, the oil content can be controlled at 5 milligrams per liter The following, the suspended matter can be controlled at 3 mg per liter, are far beyond the required indicators. Stratum "drinking" pure water, low-permeability oilfield development "enough water injection, water injection, fine water injection, effective water injection" provides a strong technical support.
Microbial membrane sewage treatment plant with a daily replenishment of 4000 cubic meters of sewage capacity, Xinmin Oil Production Plant oil-water treatment station installation of the device, the average daily sewage treatment 2,600 cubic meters, as of early August, the sewage has been treated 570,000 cubic meters. After the application of the technology, it effectively reduces the clogging of the formation space by the suspended matters, thereby enhancing the oil recovery and providing a sufficient and sufficient water source for oilfield waterflood development. In addition, compared with the original treatment of water technology, the process is simple, high degree of automation, staff labor intensity, operating costs are significantly reduced.
At present, dry mining area to 11 stations and other microbial membrane treatment system is under construction, Jilin Oilfield has begun large-scale promotion of the technology.
