In a position sensing and indicating apparatus for use in a borehole: a housing arranged to be suspended in a borehole on a cable; a first angle detecting unit; a second angle detecting unit; counter means, means for supplying pulses to said counter, means for generating signals indicative of the angular disposition of said first and second units; means responsive to such generated signals for operating said counter; means for storing countered pulses corresponding to such generated signals; and surface means for providing an indication of such angular disposition in response to such stored counted pulses.
Claim 2
Dependent Claim
96 words
In a position sensing and indicating apparatus for use in a borehole: a housing arranged to be suspended in a borehole on a cable; a first angle detecting unit; a second angle detecting unit; counter means, means for supplying pulses to said counter, means for generating signals indicative of the angular disposition of said first and second units; means responsive to such generated signals for operating said counter; means for storing countered pulses corresponding to such generated signals; and surface means for providing an indication of such angular disposition in response to such stored counted pulses.
Claim 3
Dependent Claim
24 words
The apparatus of claim 1 wherein said first and second angle detecting units are mounted in said housing in planes 90* to one another.
Claim 4
Dependent Claim
67 words
The apparatus of claim 1 wherein said signal generating means includes means for scanning said angle detecting units and means for generating a first reference signal indicative of a reference mark on the housing and a second signal corresponding to the angular disposition of the angle detecting units relative to said reference mark, said first reference signal and said second signal being used to operate said counter.
Claim 5
Dependent Claim
83 words
In a position sensing instrument: a housing; angle detecting means in said housing for measuring a parameter of the angular disposition of the housing; azimuth position sensing means in said housing for measuring a parameter of the azimuthal disposition of the housing; means for generating signals indicative of such angular and azimuthal parameters; pulse generating means; pulse counting means; means responsive to said signal generating means for operating said pulse counting means; and surface means for providing an indication of such counted pulses.
Claim 6
Dependent Claim
83 words
In a position sensing instrument: a housing; angle detecting means in said housing for measuring a parameter of the angular disposition of the housing; azimuth position sensing means in said housing for measuring a parameter of the azimuthal disposition of the housing; means for generating signals indicative of such angular and azimuthal parameters; pulse generating means; pulse counting means; means responsive to said signal generating means for operating said pulse counting means; and surface means for providing an indication of such counted pulses.
Claim 7
Dependent Claim
39 words
The apparatus of claim 4 wherein said angle detecting means includes means in said housing for indicating a reference position; and means in said housing for indicating the position of a member independent of the position of said housing.
Claim 8
Dependent Claim
59 words
The apparatus of claim 5 wherein said signal generating means includes means initiating a first signal indicative of the reference position on said housing for operating said pulse counting means; and means initiating a second signal indicative of the relative position of said member to said reference position on said housing for stopping the operation of said counting means.
Claim 9
Independent Claim
135 words
A method for determining the disposition of a borehole within the earth relative to the earth''s surface, comprising the steps of: lowering a housing into the wellbore; detecting and measuring a parameter of the angular disposition of a first plane of said housing; detecting and measuring a parameter of the angular disposition of a second plane of said housing 90* to said first plane; detecting and measuring a parameter of the azimuthal disposition of said housing; generating electrical signals within said housing which are representative of the measured parameters; supplying timed pulses to a counter; operating the counter in response to such generated electrical signals; transmitting data corresponding to such counted pulses to the earth''s surface; and calculating from the transmitted data, the position of such housing in the borehole relative to the earth''s surface.
Claim 10
Independent Claim
135 words
A method for determining the disposition of a borehole within the earth relative to the earth''s surface, comprising the steps of: lowering a housing into the wellbore; detecting and measuring a parameter of the angular disposition of a first plane of said housing; detecting and measuring a parameter of the angular disposition of a second plane of said housing 90* to said first plane; detecting and measuring a parameter of the azimuthal disposition of said housing; generating electrical signals within said housing which are representative of the measured parameters; supplying timed pulses to a counter; operating the counter in response to such generated electrical signals; transmitting data corresponding to such counted pulses to the earth''s surface; and calculating from the transmitted data, the position of such housing in the borehole relative to the earth''s surface.
Claim 11
Dependent Claim
36 words
The method of claim 7 wherein said calculation involves making a vector summation of the angular parameters measured in planes 90* to one another, and orienting such vector summation with respect to the measured azimuthal parameters.
