抽油井测试是一个难度很大的新的技术课题,目前正处于研究、发展阶段。据了解,目前国内外抽油井测试主要有四种方法,即:双油管法,临时气举法,抽测法和环空法。以上四种方法各有其特点及相应的适用范围。我们全面分析比较认为,环空法虽然技术难度大,但有测试不起泵、不停产的明显优点,故选择环空法进行试验研究是很有价值的。环空测试的主要技术关键有两个方面,一是起下工艺,二是小直径仪器。我们从环空起下工艺着眼,从简单仪器入手,1978年开始研究,经过两年多的努力,研
Oil well test is a very difficult new technical issue, is currently in research and development stage. It is understood that at present there are four main methods of pumping wells at home and abroad, namely: double tubing method, temporary gas lift method, sampling method and annulus method. The above four methods have their own characteristics and the corresponding scope of application. Our comprehensive analysis and comparison shows that although annulus method is technically difficult, it has obvious advantages of not being able to test pumps and stopping production. Therefore, it is of great value to select the annulus method for experimental research. There are two main aspects of the main technical test of the annulus. One is to start the process and the other is to use a small diameter instrument. We started from the ring under the process of technology, starting from a simple instrument, began to study in 1978, after two years of hard work, research
