Abstract: This invention discloses an intelligent water detection tool for horizontal wells, including a water detection instrument, and also including a floating-diving component for driving the movement of the water detection instrument, a buoyancy device connected to the water detection instrument, and a buoyancy adjustment component for adjusting the water displacement volume of the buoyancy device. This invention provides an intelligent water detection tool for horizontal wells, using a completely different technical approach to achieve floating-diving style water detection operations in horizontal well sections, aiming to reduce tool friction and facilitate easy passage through horizontal sections.
