Description
Technical Field
The invention relates to the field of petroleum and natural gas exploration and other construction fields requiring drilling fluid parameter recording, in particular to a device and a method for testing a downhole pump diagram of a carbon rod lifting system.
Background
At present, carbon fiber sucker rods are increasingly widely applied to oil fields by virtue of the advantages of light weight, high strength, corrosion resistance and the like. The material characteristics of the carbon fiber sucker rod are greatly different from those of the conventional steel sucker rod, and the downhole movement rule is not completely mastered at present. Downhole pump work diagram analysis is an effective means for reflecting the motion rule of a rod column, and currently, there are two main methods for testing the downhole pump work diagram of a rod pump, the first method is to calculate the downhole pump work diagram according to a measured ground work diagram, but no suitable calculation model exists for a carbon rod system. The second is direct test, which is based on measuring the acceleration of the column to calculate the displacement of the column and then generating a work pattern based on the displacement and the load. The smaller modulus of the carbon rod, the larger expansion and vibration in the well, can cause the measurement misalignment of the method. It follows that existing downhole pattern testing techniques are not adaptable to carbon rod lifting systems.

Through the multiple diversion of electrons in the incidence part, the electrons can be more concentrated in the process of travelling in the incidence part, so that the electrons can be concentrated in a region relatively after leaving the incidence part, and the number of the received electrons in the unit area of the region is increased.
