The first round of fracturing in the Jimusar shale oil field in Xinjiang Oilfield in 2024 is nearing completion, and the second round of fracturing implementation has been fully launched. In the development of Jimusar shale oil, Xinjiang Oilfield has adopted a volume fracturing technology system based on "fracture-reservoir matching + precise transformation + full-area support", which has promoted the high-quality and high-efficiency production of Jimusar shale oil.
Strengthen the multi-professional integrated fine design to further improve the benefits of fracturing. Technical personnel tackled the three-dimensional geological modeling technology with logging-level accuracy, and improved the "one well, one project, one section, one parameter" differentiated design model based on reservoir quality and trajectory, further improving the fracturing effect and benefits.
Strengthening the integrated and complex prevention and control of multiple measures to further improve the quality of fracturing. Focusing on the two problems of casing change and fracturing interference that affect the overall efficiency of the group's fracturing implementation, the technical staff iteratively upgraded the fracture identification technology and the safe and efficient transformation technology of the risk section, and formulated a "15-minute interference disposal process" based on "construction + Internet of Things monitoring linkage" to minimize casing change and interference and reduce the impact on the overall fracturing effect.
Strengthen the integration of multiple departments to speed up and further improve the efficiency of fracturing. Based on the monitoring and evaluation results of the scope and magnitude of fracturing interference between new wells in the fracturing area of ??the shale oil group, Xinjiang Oilfield upgraded the standard factory zipper operation mode of different platforms, and the collaborative efficiency was improved by more than 50%.
At present, the fracturing work of Jimusar shale oil horizontal wells is progressing steadily, and horizontal well volume fracturing technology has become an important technical means for the development of continental shale oil.
