Abstract: It is shown by reviewing the nearly 70 years’ development history of reservoir stimulation technologies that reservoir stimulation technologies experiences three main stages of involving in, integrating into and leading oil and gas reservoir exploration and development, which manifests the important bridge effect of reservoir stimulation technologies in various stages of oil and gas exploration and development. And the low-cost stimulation technologies characterized by electric fracturing pump, soluble bridge plug, slickwater and quartz sand, factory-like operation and three-dimensional fracturing are innovated. In this paper, the requirements of 14^th Five-Year Plan and future oil & gas and new energy resource development for reservoir stimulation technologies were analyzed based on China’s “three-step” energy strategic and technical roadmap. In addition, the “two-increase, one-decrease” development direction of reservoir stimulation technologies to ensure the cost-effective productivity construction of oil and gas resources in China was pointed out, and the important space of reservoir stimulation technologies for the realization of “whole industrial chain” development in terms of geothermal resource development, underground coal gasification, hydrate development with precious and rare metal, and carbon neutrality and storage was forecasted. The research results provide a reference for the high-quality development of reservoir stimulation technologies.
