在充满钻井液的井筒中投放体下落运动分析

Motion of drop-in objects in wellbore filled up with drilling fluid

在石油地质钻探或开采中,需要向充满钻井液的井筒中投放工具和仪器。通过对这种投放体的运动分析,得出了相应的计算公式,按计算公式得出的计算值与现场实测值相比,计算精度相当高。

In the course of drilling or production, it is sometimes necessary to drop a tool or an instrument into a wellbore filled up with drilling fluid. By analyzing the motion of the drop-in object, relevant formulas are worked out. The values calculated by use of the formulas are very close to the data measured on site.
