石兰原油管道采用管道部分充热水、以油顶水、综合热处理的投产方式。针对投产过程中出现的异常工况,提出了相应的解决措施:泵出口阀开关异常,检查阀门信号与实际状态是否同向;液体管道投产过程中无流量显示,采用泵曲线、清管器跟踪以及摩阻损失计算等方法估算流量;根据管道倾角和清管器速度估算管内流体经过高点后的流速,高点后管道仍处于不满流状态,是管道沿线起伏较大且油水界面间未使用清管球隔离造成的,应适当采取减少混油的有效措施。 Portland crude oil pipeline using hot water pipe to the top water, integrated heat treatment operation. In view of the abnormal working conditions in the process of putting into production, the corresponding solutions are put forward: the pump outlet valve switch is abnormal and the valve signal is checked whether it is in the same direction with the actual status; no flow is displayed during the liquid pipe production, the pump curve and pig tracking And the friction loss calculation method to estimate the flow rate. According to the pipeline inclination and the pig speed, the flow velocity of the fluid in the pipe after the high point is estimated. After the high point, the pipe is still in the state of dissatisfaction, which is undulating along the pipeline and unused between the oil-water interface Caused by the segregation of ball pipes, should be properly adopted to reduce oil mixing effective measures.

随着“林妹妹”陈晓旭患乳腺癌的离去,乳腺癌引起了女性朋友的高度重视。中外的营养学家通过长期的临床研究指出,女性乳腺癌的发生除受到自身诸多因素的影响外,还与饮食有着很大的关系。  通过食疗辅助治疗乳腺癌,在选择食物时很有讲究。中医认为,疾病有寒、热、虚、实之分,食物也有寒、热、温、凉之别。寒病用温热之食,热病用寒凉之品,以食物之偏来纠正疾病之偏,达到治病的目的。例如阴虚内热症候,临床上若见于癌症合并
