一、问题的提出和意义石油是一项重要的能源。为了更多,更好地采油,应用更先进的采油方法和护井方法,需要经常了解油井的生产状态.而目前评价注采井的状态通常是在地面上进行的,用量油罐,分离器等设施测出数据再经计算得出结果.这些数据不够完整,也不够准确。因为它只能说明原油到地面以后的平均物理参数,无法说明井内各层产出流体的性质和数量。于是很自然地提出这样一个问题,即如何在地面上测出几千公尺深的井下各层的静态和动态状况,各产出层产出流体的性质,是油、
First, the question raised and significance Oil is an important source of energy. In order to obtain more and better oil, the application of more advanced oil recovery methods and well protection methods requires frequent knowledge of the production status of oil wells, and the current status of injection and recovery wells is usually evaluated on the ground. Oil tanks, separators And other facilities measured data and then calculated the results of these data is not complete enough, not accurate enough. Because it can only show the average physical parameters of the crude oil after the ground, it can not explain the nature and quantity of the fluid produced in each layer of the well. It is therefore natural to ask the question of how to measure the static and dynamic conditions of the underground formations at a depth of several thousand meters on the ground. The properties of the fluid produced by each producing layer are oil,
