Abstract

The invention provides a reaction and seepage characteristic integrated test method and device in an oil reservoir. Simulation reaction in the oil reservoir is performed through an integrated test unit, permeability testing is performed on reacted rock cores, permeability parameters during permeability testing is measured, the permeability of the rock cores after the simulation reaction is calculated according to the parameters, physical parameters of a reaction model and physical property parameters of injection high-pressure fluid, and accordingly, simulation reaction and permeability testing in the oil reservoir are achieved simultaneously through one device, and permeability testing is performed on the reacted rock cores creatively. The method and the device can be used for determining influence rules of simulation reactions to seepage characteristics.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to an integrated test method and device for reaction and seepage characteristics in oil reservoirs. Background technique [0002] Oilfield development experiments are one of the important means for the research and development of new technologies and methods for enhanced oil recovery. With the continuous reduction of conventional recoverable oil and gas resources and the increasingly complex development objects, the traditional water flooding technology can no longer meet the needs of oil and gas field development. To meet the challenges, it is urgent to develop a group of chemical flooding, thermal oil recovery and gas flooding. New technologies for tertiary oil recovery put forward new requirements for oilfield development experiments. [0003] In the process of oilfield development, mastering the change of seepage characteristics of reservoir fluid is very important for the...

Problems solved by technology

[0012] None of the existing permeability measurement devices can simulate the high temperature conditions of the reservoir. The actual reaction of the reservoir may reach a maximum temperature of 600°C. These permeability test systems can simulate the maximum temperature condition of 200°C, which cannot meet the simulation requirements of the reservoir reaction.

[0013] In summary, the existing experimental methods and devices for oilfield development cannot meet the requirements of measuring the seepage characteristics of the reservoir while simulating the chemical reactions in the reservoir
