Embodiment 1

[0035] Embodiment 1, the working arrangement method of conducting the current field, includes the following steps:

[0036] Step 1: Set up two electrode points, connect the two electrode points with insulated wires, and use insulated wires between the two electrode points to connect to the two output ends of the transmitter respectively. If the underground half space is uniform and infinite half space, then the current field output by the transmitter to the first electrode point flows from the current line to the underground half-space in a radial shape near the first electrode point, and then in a radial shape, all of it is sent back from the second motor point in a radial shape. machine;

[0037] Step 2: Connect one end of the transmitter to a dew point of the target pipeline under test with a wire, then connect one end of the transmitter to the first electrode point, and the other end of the transmitter to the second electrode with a wire point, when single-ended charging,...

Embodiment 2

[0040] Embodiment 2, step 1 comprises the following steps:

[0041]The first electrode point and the second electrode point in step 1.1: are more concentrated near the electrode connection line, that is, the current density is larger, and the farther the first electrode and the second electrode are or the deeper they are from the ground, the larger the current density.

[0042] Step 1.2: When the central third section of the line connecting the two electrode points, both sides and depth are the central sixth section of the line connecting the two electrode points, the distribution of the current field can be regarded as a uniform field, and the local When the lower half space is a non-uniform half space, the current always tries to pass through the path with the smallest impedance. When there are underground pipelines with good conductivity in the current field, if the current lines and the underground pipelines are oblique or parallel, the current can be "attracted". , so tha...

Embodiment 3

[0043] Embodiment 3, step 2 comprises the following steps:

[0044] Step 2.1: During the conduction process of the current in both directions, the distribution parameters between the pipeline and the ground will weaken as it gradually moves away from the first electrode point, and will be dispersed to the ground, and the current dispersed to the ground will all flow to the ground. Second motor point, via wire to the other output of the transmitter.

[0045] Step 2.2: During detection, although the current is gradually attenuated, the inversion problem can still be handled according to the line current during detection. In order to avoid the influence of the magnetic field generated by the power supply wire on the magnetic field generated by the target underground pipeline during detection: ① The power supply wire can be arranged perpendicular to the direction of the pipeline; ②Select a detection method that is less affected by the power supply wire on the ground, such as the m...

Abstract

The invention relates to a working arrangement method for conducting a current field, and the method comprises the following steps: 1, setting two electrode points, connecting the two electrode points through an insulated wire, respectively connecting the two electrode points to two output ends of a transmitter through an insulated wire, and if an underground half space is a uniform infinite half space, so that the current output from the transmitter to the first electrode point radially flows into the underground half space through the current line near the first electrode point, and then all radially returns to the transmitter through the second motor point. According to the invention, the current fields in different states can be conveniently arranged through a plurality of power supply modes, and the arrangement mode is relatively comprehensive; and the method can adapt to different states of a single measured target pipeline exposure point, a double-end target pipeline exposure point and no exposure point.
