Abstract
A testing device and method for floating rate of floating agent for fracture height control are provided. The test device includes a support frame, a glass tube vertically fixed on the support frame, a floating agent storage container, a control valve, and a liquid storage tank, wherein multiple circular holes are uniformly distributed along an axial direction of the glass tube, and multiple turbidimeters for measuring liquid turbidity are sequentially mounted on the circular holes. The liquid storage tank communicates with an inner cavity of an upper end of the glass tube through a pipeline, and the floating agent storage container is connected to an inner cavity of a lower end of the glass tube through a control valve. The present invention increases accuracy of measured floating rate of the floating agent, and provides reliable floating data of the floating agent for oil and gas reservoir reconstruction.
