储存式磁定位压力计的研制

Development of a Stroage Magnetic Positioning Pressure Meter

针对试井测试中深度测量不准确的问题,研制了一种新型储存式磁定位压力计,该仪器由地面控制仪和井下仪器两部分组成。给出了井下仪器的组成、工作原理及主要技术指标。该仪器采用流压测量及静压测量两种测量方式,可以精确测量出仪器停放位置的深度。实际应用测量误差小于±10cm。

In consideration of the problems of inaccuracy of depth measurement in well testing, a new storage magnetic positioning pressure meter is developed, which is consisted of a surface control tool and a downhole tool. The composition, working principles and key technical indications are also given. The method of flow pressure and static pressure measurements are used in the meter, by which the depth of tool position can be measured accurately. Error of its field application is less than ± 10cm.
