准确的密度测量对于油田固井和压裂作业非常重要。固井水泥浆和压裂液都含有大量的颗粒物质,在高压液体的携带下,细小的颗粒具有很强的冲刷和切削力量,对接触式测量仪表的核心部件都具有很强的破坏性,甚至会损坏仪表。研制了一种新型的不用核材料的非接触测量装置,作为井口数据的终端测量装置应用于油田密度、砂比、流量的测量。介绍了该装置的结构原理及在油田现场的应用情况。
Accurate density measurement is very important for oilfield cementing and fracturing operations. Cementing fluids and fracturing fluids contain a large amount of particulate matter. Under the condition of high-pressure liquid, small particles have strong scouring and cutting forces, which are very destructive to the core components of contact measuring instruments. Can even damage the meter. A new type of non-contact non-nuclear material measuring device was developed. It is used as the terminal measuring device for wellhead data to measure the density, sand ratio and flow rate of oilfields. The structure and principle of the device and its application in oil field are introduced.
