Current Situation and Existing Problems of Horizontal Well Fracturing Technology

Horizontal wells offer numerous advantages in the petroleum industry, making them a focal point for research and practice. These wells have a large drainage area, high well output, extensive penetration, high reserve utilization, and the ability to avoid obstacles and challenging environmental conditions. However, in low permeability oil and gas reservoirs, horizontal wells face challenges such as poor connectivity and seepage resistance which hinder production from meeting economic development requirements. To address these challenges, domestic and international fracturing designs for horizontal wells have been developed. Staged fracturing technology for horizontal wells has also been implemented to improve production efficiency. Despite these advancements, there are still main issues present in horizontal well fracturing that need to be addressed This paper aims to provide insights into the various techniques used in fracturing horizontal wells both domestically and internationally. By addressing the challenges encountered in horizontal well fracturing and proposing potential solutions, this paper can serve as a valuable reference for similar reservoir developments. It is crucial for the petroleum industry to continue researching and advancing current technologies to optimize the productivity of horizontal wells in order to effectively meet economic development demands.
