Reservoir Damage Characteristics and Protective Measures under the Coupling Effect of Temperature and Pressure

Abstract

In the exploitation of oil and gas fields, the coupling effect of temperature and pressure on the reservoir brings many problems. Temperature rise changes rock properties and accelerates reservoir damage. Reservoir damage includes physical, chemical and biological aspects, including permeability decrease, pore structure deterioration, rock fracture and fracture expansion. Preventive measures such as optimization of completion fluid system, temperature control and pressure management, as well as chemical, physical and microbial remediation are proposed to provide technical support for reservoir damage prevention and control, which is of great significance for improving oil and gas production efficiency and ensuring energy supply.
