Optimization of Temporary Plugging Scheme for Horizontal Well Fracturing
摘要
Abstract
Fracturing construction of offshore low-permeability reservoirs is restricted,and temporary plugging fracturing of horizontal wells can break through the bottleneck of offshore fracturing technology,which is the direction for efficient development of offshore low-permeability reservoirs.Due to the limitations of construction conditions,onshore temporary plugging technology cannot be directly ap-plied to offshore oil fields,and targeted research on offshore horizontal well temporary plugging fracturing technology has not yet been carried out.Considering the crack morphology,plugging experiments of the cracks with different crack widths(1～8 mm)that withstand high pressure were conducted,and the plugging agent formula was optimized.Based on the geological-engineering integrated platform,a three-dimensional fracturing model for offshore horizontal wells was established to clarify the impact of temporary plugging timing and temporary plugging agent dosage on the competitive expansion of multiple fractures within the section.The research results indicate that increasing fiber concentration and main bridging particle size is key factor to plugging wide cracks.Taking Chenghai horizontal well frac-turing as an example,when temporary plugging agent dosage is 1/4 of initial dosage and the temporary plugging timing is at 1/4 moment of fracturing time,the fluid flowing into multiple fractures in the section is more uniform,the propagation of multiple fractures is more balanced,and the overall stimulation effect is better.关键词
