西区油田常温集输过程清管周期研究

Study on Pigging Period of Normal Temperature Gathering and Transportation Process in Xiqu Oilfield

根据西区油田常温集输过程的黏壁规律,给出了通球周期计算公式,并且据此开发了通球周期计算软件。重点计算并分析了不同含水率、流体温度对通球周期的影响,得到温度对周期影响占据主导因素,并进一步分析了环境温度对管道通球周期的影响规律。研究所得结论对于西区油田常温集输过程清管周期的确定和清管工作的实施具有重要指导意义。

Based on the wall sticking law in the normal temperature gathering and transportation process of Xiqu oilfield,the pigging period formula is obtained.And the pigging period computational software interface is developed based on the formula. The effects of water cut and fluid temperature on pigging period are calculated and analyzed.It is found that the effect of fluid temperature is the leading factor,and the effect of ambient temperature on the pigging period is analyzed further.The studying results will have important guiding significance on the determination of pigging period and the implement of pigging work for the normal temperature gathering and transportation process of Xiqu oilfield.
