Description

technical field [0001] The invention belongs to the technical field of heavy oil chemical catalytic cracking simulation experiments in oil production chambers, and in particular relates to an ultrasonic-assisted heavy oil chemical catalytic cracking static simulation experiment device and method. Background technique [0002] With the continuous reduction of conventional oil resources and the continuous increase of world oil demand, heavy oil / super heavy oil resources, which account for a large proportion of oil and gas resources, have been paid more and more attention. The salient features of heavy / ultra-heavy oil are high density, high viscosity, and poor fluidity, which lead to many difficulties in intra-layer flow, wellbore lifting, surface gathering and transportation, and refining and processing of heavy / ultra-heavy oil. At present, steam injection thermal recovery is generally used for heavy oil production. Because conventional steam injection thermal recovery is main...
