As the main battlefield for crude oil processing at No. 2 Oil Production Plant, the current gathering and transportation team has a daily capacity of nearly 10,000 cubic meters. Due to the great changes in the physical properties of the incoming crude oil, demulsifiers that have been used for a period of time may have poorer dewatering efficiency after a period of time, resulting in increased oil content of the oil delivery and severely affecting the normal operation of the gathering system.
For this reason, a large team of gathering and transportation started from the production reality that ensures the safe and stable operation of the system, and constantly selected and tested the demulsifier types and ratios, and formed a long-term mechanism. In view of the recent increase in new wells and sour wells, the difficulty in dehydration of crude oil has increased. The team’s technicians have started hands-on, through laboratory tests, field comparison methods, adjusting the model and ratio of demulsifiers and related operating parameters, after crude oil treatment The SLD7007 demulsifier with more emulsified layers was converted to SLD7007: after the SLD5010 ratio was 4:1, the emulsified layer was significantly reduced, the water content of the purified oil was reduced from 0.4-0.5% to 0.2-0.3%, the effect of technical modification was obvious, and the crude oil processing system was stable. The operation is effectively guaranteed; at the same time, an additional demulsifier injection point is added to the TK7-444 oil treatment station to treat crude oil in some new wells and acid wells and then enter the two-link system, reducing the possibility of collecting oil from the source due to changes in physical properties. The fluctuation caused by the smooth operation of the system.
The multi-measure demulsifier model and the technology with continuously improved proportioning have not only ensured that the oil content of the externally-delivered purified oil is within the specified range of 0.5%, but also the qualified rate of the oil product reached 100%, and the amount of the demulsifier was also reduced, and the amount of demulsifier was also reduced. The amount of repetitive treatment of liquids has promoted cost reduction and efficiency enhancement and saved a lot of production costs.
