Abstract
The invention discloses a multi-phase fluid oil displacement and pulse unblocking integrated physical simulation experiment device and method. The device mainly comprises a multi-phase fluid generation and storage system, a multi-phase fluid spreading and impulse wave generation system, a reservoir core simulation system and a dynamic experiment data collection system. The multi-phase fluid spreading and impulse wave generation system comprises a multi-phase fluid injection pipeline, a pulse oscillation generation cavity casing, a collision body and a multi-phase fluid output and pulse wave spreading pipeline. The device mainly utilizes difference of gas and liquid elastic modulus to achieve conversion between pulse unblocking/oil displacement and gas (steam) injection functions to simplify the oil displacement/pulse simulation process in different oil reservoir exploitation processes. The experiment can relate to simulation of experiment processes of miscible-phase displacement and gas water alternative oil displacement, reservoir pulse unblocking, thick oil thermal exploitation storage layer steam injection, oil displacement-unblocking and the like. The device is reasonable in design, simple in operation process and capable of effectively simulating the multi-phase fluid oil displacement and pulse unblocking effects.
