摘要
通过对油气井注脂系统水力学模型的分析,抓主要因素、忽略次要因素,对该系统井上及井下两段流道的注脂量及阻流管长度建立起数学关系。通过讨论,明确了如何根据井内压力,采取措施,在注脂口建立起可靠的密封压力。
By analyzing hydraulic model of greasing system in oil and gas wells,focusing on key factors and ignoring the secondary factors,a mathematical relationship between the flow volume,which is two flow sections of surface and underground,and the length of grease flow tube is established.Through discussion,how to take measures to establish a reliable sealing pressure at the mouth on basis of the well pressure is clear.
