Application of geothermal reservoir modification technologies and prospective

The reservoir modification technology is an effective means to improve the development capacity of deep thermal reservoirs. It increases the heat transfer capacity between the rock and the fluid by increasing the permeability of the thermal reservoir, maximizing the exploitation of the thermal energy in the rock. This paper reviews the development history and the production enhancement principle of the acidification technology in reservoir modification technologies, compares the relevant cases and researches of the acidification production enhancement carried out in the canonical geothermal fields abroad, as well as the commonly used acidic chemical stimulants and the production enhancement effects. By analyzing the experience and the lessons learned from the reservoir modification abroad, some guidance is provided for the modification of deep carbonate thermal reservoirs t in China.
