As an innovative technology in the current development of oil and gas fields, horizontal well volume fracturing technology plays a decisive role in the development of unconventional oil and gas reservoirs. By injecting high-pressure cracking fluid into the formation, this technology causes rock fracture to form a complex fracture network, greatly expanding the flow path of oil and gas from the reservoir to the wellhead, and effectively improving the oil and gas recovery. The scientific principle behind horizontal well volumetric fracturing technology is deeply discussed, and the key technical parameters of the technology are analyzed in detail, such as the property of fracturing fluid, the formation and propagation of fractures, and the precise control of fracturing operation. At the same time, the technical challenges and environmental risks encountered in the actual operation of horizontal well volume fracturing technology are discussed, and specific countermeasures and optimization methods are put forward. Through the analysis of several examples, the significant effects of horizontal well volume fracturing technology in improving the development efficiency and reducing the development cost of unconventional oil and gas fields are demonstrated, and its future application prospect and development direction are prospected, emphasizing the importance of continuous technological innovation in realizing the efficient development of unconventional resources.
