Oilfield water (waste) testing

Oilfield wastewater comes from processes such as drilling, oil extraction, and well washing in oil and gas extraction. Therefore, the composition of oilfield wastewater is complex, consisting of organic and inorganic mixtures, and also involves the distribution of organic matter in the water and oil phases. After steam thermal recovery, tertiary oil recovery, and other treatment processes, the oil contains colloidal asphaltene, fatty acid substances, mercaptans, and similar substances, which enter the water phase in a certain form under certain conditions, Causing significant changes in the relative composition of organic matter in water and oil. Fatty acids and glial asphaltenes in oil are natural emulsifiers that form emulsified oil with oil during thermal recovery, tertiary oil recovery, and formation migration. Therefore, the oil in wastewater mainly exists in the form of emulsified oil and free oil. After oil-water separation at the settling station, a considerable portion remains in the aqueous phase. According to relevant analysis results, the main components in oily wastewater include heavy crude oil, fatty acid substances, demulsifiers, mercaptans, resins, sulfides, carbonates, sulfates, etc. Due to the complex composition of residual organic and inorganic substances in water, it has brought certain difficulties to the treatment of oilfield wastewater. Although the water quality of each oilfield varies, overall it has the following characteristics: high mineralization, accelerated corrosion rate, and also caused difficulties in biochemical treatment of wastewater; High oil content, far exceeding the water quality standards required for various outlets; Containing a large number of microorganisms, the proliferation of bacteria not only corrodes pipelines but also causes serious blockage of the formation; Contains a large amount of scaling ions, and the extracted water contains easily scaling ions such as SO42-, CO32-, Ca2+, Mg2+, Ba2+, etc; Suspended solids (polymer injection zone) have high content, small particles, and are prone to formation blockage
