Zusammenfassung:The embodiment of the invention discloses a gas production and water production profile testing method and device and a computer storage medium, and belongs to the technical field of coal bed gas development. The method comprises the steps that a layering tester is controlled to descend to a target position from an eccentric wellhead of a target coal-bed gas well, the layering tester is located in an oil sleeve annulus of a production layer section, and the target position is a first distance position below the bottom boundary of a lowest position coal bed of the target coal-bed gas well; controlling the layered tester to rise from the target position; and in the rising process of the layering tester, the gas production and water production profile test of the target coal-bed gas well is conducted through the layering tester. According to the method, the layering tester is tripped into the oil jacket annulus of the production layer section from the eccentric wellhead, the layering tester starts to be slowly l
