It is reported that Fuling Jiaoye 18-S12 well, which was undertaken by Jianghan Petroleum Engineering Downhole Testing Company for fracturing construction tasks, has recently completed 57 sections of fracturing construction, breaking the record for the highest number of shale gas fracturing sections in Sinopec.
With the deepening of shale gas exploration and development, in order to achieve “high-yield and efficient development with fewer wells”, the horizontal section of horizontal wells is becoming longer and longer. Currently, there are ultra long horizontal wells with a horizontal section length greater than 3000 meters. The longer the horizontal well, the more fracturing segments there are. How to safely and efficiently perform segmented fracturing has always been a challenge. The Jiaoye 18-S12 well under construction this time has a depth of 7161 meters and a horizontal section length of 4256 meters. It is the longest shale gas horizontal section well in China, with a fracturing design of 57 sections. It is also the first large-scale hydraulic fracturing well of Sinopec with more than 50 sections.
The successful implementation of fracturing construction in this well marks a significant breakthrough in the fracturing technology of ultra long horizontal shale gas wells in China, providing strong support for effectively increasing the reserve utilization rate of oil and gas reservoirs, improving single well recoverable reserves, and reducing single well development costs.
