摘要 |
<p>A well tool is suspended in a well by an elongated support member extending between the tool and surface equipment. The well tool is anchored to the well tubing string at a location within the well where the tool is to be operated. A tension in excess of that resulting from the weight of said tool and of said support member are imposed on the support member to establish a reference value tension in said support member. Variations in tension from said reference tension are induced at a first location on said support member in a pattern in accordance with the data/control signals to be transmitted. Variations in tension at another location on said support member are then detected. <IMAGE></p> |
