Embodiment Construction
[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0024] like figure 1 and 2 As shown, the embodiment of the present invention provides a circumferential (array) conductance probe sensor for measuring the dynamic full water value of a horizontal well, which includes a cylindrical insulator support 1 and 12 probes fixed on the inner wall of the insulator support 1. Needle electrodes 2, 12 probe electrodes 2 including 6 excitation electrodes (E 1 ~E 6 ) and 6 measuring electrodes (M 1 ~M 6 ), 6 excitation electrodes (E 1 ~E 6 ) is located in the circumferential direction of the upstream axial section of the inner wall of the bracket 1, and is evenly spaced, and the remaining 6 measuring electrodes (M 1 ~M 6 ) is lo...
