March 16 data show that: g single daily oil pipeline capacity has grown from 3,000 tons last year to upgrade to the current 4,000 tons. Transported every day that 1,000 tons of crude oil, from the Xinjiang Oilfield Company in Luliang and stone oilfield. This means that the two fields of crude oil every winter to stop transmission of the history to an end. Lu Liang, Shi lose the West main crude oil and petrochemicals to Dushanzi Petrochemical Karamay. Freezing point of their oil as high as 16 degrees Celsius, that is, in the ground temperature is 16 degrees Celsius, the oil loses its mobility. Because of its high freezing point in winter transportation is always a difficult problem. Plus grams of independence D219 \ D273 line of small diameter transmission exists, the temperature dropped, causing inlet temperature close to or below its freezing point, run high risks. Ciu also exists in the transmission line along the issue of lack of heat load, by simply pumping methods can not be piped. In the past, these two 23 month per year of crude oil in Ciu line shutdown, last December to the year in May alone in the g line shutdown, the annual total shutdown time up to 8 months. During shutdown, the new oil field production of crude oil can only be stored in 701 large pot tank, wait until the temperature rise after the delivery. Winter shutdown, so that Dushanzi decline in crude oil needs, but also to the Xinjiang Oilfield Gas Storage and Transportation Company stock balance to be difficult. In this context, the Xinjiang oil and gas storage and transportation alone in grams conducted online by DRA transmission experiments, to enhance high pour point crude oil transportation technology research. Oil DRA is a polymer chemicals, can reduce the liquid in the pipe flow resistance. After much analysis and the experimental operation, last winter, the Xinjiang oil and gas storage and transportation company in the station of Croatian independence, four pumping stations filling DRA, so that the transmission line from the usual daily volume of 3,000 tons per day to 4,000 tons of pipe bed temperature also will improve the smooth delivery for the winter and stone Luliang West created the conditions of crude oil. Xinjiang's oil and gas storage and transportation company, according to statistics, only in February this year, the Croatian independence had accumulated transmission lines and stone oilfield Luliang 47,600 tons of crude oil. |
