Early April, as the Great Wall the weather gradually warm, huabei oilfield company has branch according to seasonal change optimizing adjustment of 1160 water mixed with water and water temperature, and can reduce production cost 750000 yuan. This is China, huabei oilfield company optimize authors set oil transfer efficiency of an instance.
In oil and gas production, well three tube heating mode of production is easy to manage, not easy to condensing tube and other advantages, but also has a fatal disadvantage of high energy consumption, especially to better crude oil property, three tube heating mode of production greatly increase the cost of production.
In order to solve this highlights the problems of energy intensive, huabei oilfield construction engineering science organization began in 2009 to carry out the single pipe oil technology promotion and corresponding oil collecting system is simplified adjustment of technical parameters of work.
At present, through continuous experiment exploration, huabei oilfield in 6158 producing Wells, two-thirds of the well to achieve single pipe or double tube watered oil collecting process mode of production, reduce energy consumption effectively. Another third Wells for block modification or poor oil properties were not the reason, still using three tube heat tracing process of production.
This year, the north China, huabei oilfield of nine, the joint station, block station gathering and transportation technology will achieve 315 single pipe oil, 746 Wells double tube watered oil.
It is understood that the company will further accelerate the speed of surface gathering system simplified optimization step, seasonal temperature continuous mining conveyor potential, fine production operation parameters, run the huabei oilfield surface gathering system to realize the mass transfer efficiency.
As of April 10, huabei oilfield has to conform to the conditions of 856 Wells to carry out the seasonal temperature conveying, down 2310 double tube Wells, all season to transmission line to reduce temperature, can save fuel nearly 2500 tons, save about 2 million cubic meters of gas.
