Abstract
Disclosed is a method of communicating data and control signals between a down hole well tool and surface equipment wherein variations in the tension of the line supporting the tool from a reference tension value established with the well tool in place for operation are imposed at one location on the support line and detected at another location on said support line said variations in tension being coded in frequency, magnitude, polarity or duration or combinations thereof to convey the data and control signals between the two locations.
Claims19
A method of communicating data and control signals between a down hole well tool and surface equipment comprising the steps of:
- suspending a well tool in a well by an elongated support member extending between the tool and surface equipment;
- anchoring said well tool to a well tubing string at a location within the well where the tool is to be operated;
- imposing on said support member tension in excess of that resulting from the weight of said tool and of said support member to establish a reference value tension in said support member;
- inducing at a first location on said support member variations in tension from said reference tension in a pattern in accordance with data/control signals to be transmitted;
- and
- detecting said variations in tension at another location on said support member.
A method of communicating data and control signals between a down hole well tool and surface equipment comprising the steps of:
- suspending a well tool in a well by an elongated support member extending between the tool and the surface equipment;
- and
- positioning the tool within the well to a location at which the tool is to be operated;
- anchoring the tool within the well;
- imposing on said support member through operation of said surface equipment added tension to establish a reference tension value in excess of the tension on said support member produced by the weight of said tool and of a supporting length of said support member;
- initiating operation of said tool;
- inducing in the support member at the tool variations in tension on the support member from said reference tension value in a pattern in accordance with data signals to be communicated to the surface equipment over a period of time;
- and
- detecting said tension variations in said support member at the surface equipment.
A method of communicating data and control signals between a down hole well tool and surface equipment comprising the steps of:
- suspending a well tool in a well by an elongated support member extending between the tool and the surface equipment;
- anchoring the tool within the well at the location where the tool is to be operated;
- imposing on said support member tension of a magnitude to establish a reference value tension;
- inducing at a first location on said support member variations in tension from said reference value tension, said variations being encoded patterns representative of the data and control signals to be communicated;
- and
- detecting said variations at another location on said elongated support member.
