摘要

摘要:
水平井砾石充填过程中因砂桥形成导致桥堵，为提高旁通通道的过流截面利用率和工作可靠性，基于旁通分流砾石充填技术原理，研制大排量旁通筛管，优化旁通通道结构，将传统旁通筛管中的充填管替换为喷砂环，形成“喷砂环-输送管”结构。通过地面物模试验和现场试验验证，相比传统型旁通筛管，大排量旁通筛管在输送管过流截面扩大47.1%，沿程摩阻压降减少53.8%，在充填速率上较传统技术提高180%，应用井投产后360天内累积产油量提高31.2%。结果表明，大排量旁通筛管具有优异的旁通通道输送能力，可实现快速循环充填，有效减轻储层污染，减少砾石与地层砂的掺混，可为提高单井产量提供一种技术手段。

Abstract:
To tackle the challenge of sand bridge-induced blockages during gravel packing in horizontal wells and to boost packing efficiency, a novel high-flow-rate shunt screen has been devised. Grounded in the principles of shunt gravel packing technology, this screen innovatively replaces the traditional packing tube with a nozzle ring within the shunt channel, establishing a "nozzle ring–transport tube" configuration. This structural modification markedly enhances the utilization rate and reliability of the shunt channel's flow cross-section. Relative to conventional shunt screens, the high-flow-rate shunt screen achieves a 47.1% increase in the transport tube's flow cross-section and a 53.8% reduction in the channel's frictional pressure drop. Laboratory modeling tests and field trials have confirmed that the high-flow-rate shunt screen delivers an 180% improvement in packing rate and a 31.2% boost in cumulative oil production over the initial 360 days of well production. These findings highlight the screen's superior slurry transport capabilities, which facilitate rapid circulation and packing, effectively minimize reservoir contamination and gravel–formation sand mixing, and ultimately lead to a substantial increase in single-well productivity.
