基于压裂船的海上大规模压裂工艺研究
Research on Large-scale Offshore Fracturing Technology Based on Fracturing Vessels
摘要
Abstract
The development of low-permeability reservoirs offshore faces significant challenges such as high costs,high risks,and high requirements.Large-scale fracturing technology based on fracturing vessels enables continuous and efficient reservoir stimulation,representing a key pathway for the economical and effective exploitation of offshore low-permeability oil and gas resources.Taking the"Haiyang Shiyou 696"fracturing vessel as an example,which enables continuous stimulation at a rate of 12 m3/min and can increase fracture half-length by 1.5 times compared to conventional offshore fracturing,the recovery factor increased by approximately 5.0 percentage points.Through a comparative analysis of hydraulic jet fracturing,pumping bridge plug-perforation combined fracturing,and cemented sliding sleeve fracturing:it is concluded that the cemented sliding sleeve fracturing,with a non-operating time accounting for only 10%∼15%,offers superior operational continuity and is best suited for the high-efficiency mode of fracturing vessels.Furthermore,key supporting technologies have been developed,including a seawater-based integrated variable-viscosity fracturing fluid system,continuous proppant supply,casing tie-back and downhole safety control.A multi-method fracture monitoring approach is also recommended to enhance post-fracturing evaluation accuracy.The research findings provide systematic technical support for the large-scale development of China's offshore low-permeability oil and gas resources and the achievement of the"fewer wells and higher production"objective.关键词
