Low permeability fine process liaohe oilfield sewage treatment has a new progress

July 3, liaohe oilfield and ridge production plant is one station on site are low permeability sewage fine processing pilot experiment was carried out. Fine new sewage treatment technology to change the original physical chemical and membrane filtration treatment way, taking microbial membrane filtration process of new technology.

low permeability sewage fine processing, according to data from the pilot test after sewage treatment level A1 for injection water quality standard, the processing costs per cubic meter of ten. 6 yuan dropped to $4. Now, liaohe oilfield is ready to expand the scale of test, make the technical improvement project as soon as possible into the industrial application.

oil field production process of industrial sewage, must pass through processing to return to the ground. Liaohe oilfield is low permeability reservoirs reserves to 1. 700 million tons, including package a and endure a 25 low permeability of water injection development blocks, such as water flooding with annual capacity of 600000 tons for size. Due to the low permeability reservoirs have a poor reservoir property, water quality of injection water demand is high, need level A1 for water injection water quality standard, has been a difficult problem in liaohe low permeability oilfield development.

microbial and membrane filtration precision processing technology compared with traditional technology, simple process, less investment, low running cost, handling cost per cubic meter of sewage is 4 yuan. This technology is through the microbial metabolism, effectively reduce the concentration of the organic matter in water, the water quality and stability is greatly increased.
