续流测井仪及其在试井中的应用

在试井界，人们不仅认识到试井早期资料的重要性，同时也认识到续流效应对试井解释的影响。为了能够充分利用试井早期资料解释地层参数，消除续流对压力的影响，缩短关井时间，文章介绍了可以同时测量压力和续流量的续流测井仪。通过将该仪器测得的压力、流量资料用于试井分析，求取地层参数，解决了试井分析中关井时间长、解释结果多解性及在低渗油田常规方法不能获得地层参数等问题。通过现场应用实例表明，该仪器不仅具有录取资料直观、准确、可靠等特点，而且具有良好的应用前景。文章就仪器的结构、测量原理及技术指标进行了阐述。

Continuous flow logging tool and its well testing application

It has been well recognized that well testing data of early stage are important and that continuous flow exerts a certain influence on well testing interpretation. A set of Logging tool which is capable of measuring pressure and continuous flow simultaneously has been developed. The problem in testing analysis, such as longer closed-in time, multi-answers of interpretation and low-permeable formation parameters which can not be obtained by conventional well testing ways, have been solved through the application of pressure and flow rate inputs obtained by the instrument. Field application confirmed its quick-look, accuracy and reliability. This paper mainly discusses the structure of the logging tool, the working principle and the field applications.
