发明名称 Horizontal wellbore pressure measurement
摘要 A system and method of measuring pressure in highly deviated or horizontal wellbores. In a described example, a pressure measurement system includes an apparatus which has a tube wrapped helically about a tubular mandrel. The tube is connected to a line extending to a remote location. A predetermined fluid is displaced through the line and the tube, so that fluid pressure in a well at the apparatus may be measured at the remote location.
