垂直井产出剖面测井仪器三相流响应特征实验研究

Experimental study on the three-phase flow response characteristics of vertical well output profile logging instrument

三相流研究一直以来即是世界级难题,而两相流研究是三相流研究的前提和基础。因此,本课题首先从两相流研究入手,针对油田高含水、低产液情况下三相流动的复杂性及仪器动态响应呈现非线性的问题,利用目前大庆油田广泛采用的阻抗式含水率计、涡轮流量计研究在垂直条件下油气水三相流专用实验装置中多相流的流动规律及测井仪器的响应特征,并将现有的油水两相流仪器通过实验应用到三相流测量中,为三相流测井资料解释和仪器研发以及油田开发方案优化调整提供技术支持。

Since three phase current research always has been a world-class difficult problem,but two phase current research are three phase current research premise and the foundation.Therefore,this topic first from two phase current research obtaining,in view of the oil field high watery,lowly produces in the fluid situation the three-phase flowing complexity and the instrument dynamic response presents the non-linear question,widely uses the impedance type moisture content idea,the turbine meter using at present Daqing Oil Field,studies under the vertical condition in the oil gas water three phase current special-purpose test installation the polyphase flow mobile rule and the logging instrument response characteristic,and will have the perquisite two phase current instruments will apply through the experiment to three phase current surveys in,will be three phase current log information explained and the instrument research and development as well as the oil-field development plan optimization adjustment will provide the technical support.
