随着油气行业进一步向成熟资产、非常规油气藏和深水前沿领域推进,有效的防砂仍然是一项关键挑战。随着油藏日益复杂,经济效益日益紧张,油气行业正转向更具适应性、数据驱动和针对性的解决方案。新的研究重点介绍了一些创新解决方案,这些解决方案不仅突破了现有设计的技术限制,还能通过数字化和跨学科集成来提升决策能力。

本期《技术聚焦》重点介绍的三篇论文反映了这一转变。每篇论文都探讨了现代防砂技术的一个独特方面:针对老井的改造筛管、利用实时建模的预测性防砂措施,以及针对叠层低流度油藏设计的先进完井技术。这些论文共同凸显了行业正朝着更智能、更因地制宜的方法迈进,这些方法将现场数据、模拟和跨学科见解相结合,以提高可靠性、降低风险并最大限度地提高采收率。

过油管砂筛管 (TTSS) 已成为老化海上油井出砂管理的首选补救方案。然而,其性能波动性仍然很大,超过 40% 的装置会过早失效。SPE 220610 号论文对马来西亚东部 125 套 TTSS 装置进行了深入分析,找出了影响筛管寿命的关键设计和操作因素。

由于过度压降导致的出砂通常会导致昂贵的干预措施和生产延期。SPE 220649 号论文介绍了一种数字化出砂管理工作流程,该工作流程结合了一维地质力学模型、出砂风险分析和井筒模拟,以计算最低油管头压力阈值,使作业人员无需井下压力表即可保持无砂流动。该工作流程通过将地质力学与自动化生产建模相结合,支持主动防砂,为数字化油田的实施迈出了宝贵的一步。

墨西哥湾威尔科克斯油田下段的开发面临双重挑战:低流动性、叠置式储层,以及对经济高效、耐砂完井技术的迫切需求。SPE 220794 号论文介绍了一种新型大角度多重压裂完井系统,该系统专为深水高岩石强度环境(无侧限抗压强度大于 5,000 psi)而设计,在这种环境下,传统的砾石充填可能不可行或没有必要。

另外三篇推荐阅读的论文为防砂提供了宝贵的视角。论文SPE 220860提供了基于现场和模型支持的分析,表明在低生产压差条件下,软弱地层中的出砂风险仍然有限。论文SPE 221020引入了一种预测方法,通过将地质力学与作业数据相结合来识别水平井的出砂风险,从而优化了射孔和生产压差策略。论文SPE 224059详细介绍了在低注入量井中成功使用外部催化树脂进行化学防砂,为机械方法效果较差的场合提供了一种持久的替代方案。

总的来说,这些论文凸显了行业从标准化解决方案向定制化、洞察驱动的防砂技术的转变。无论是通过改进筛管设计、改进地质力学工作流程,还是采用下一代完井系统,未来的道路都依赖于学科、技术和数据的整合。

Sand Management-2025

As reservoirs become more complex and economics tighter, the industry is shifting toward more-adaptive, data-informed, and targeted solutions. New research highlights innovative solutions that not only address technical limitations in existing designs but also enhance decision-making through digitalization and cross-disciplinary integration. The papers highlighted here reflect this shift.

As the industry pushes further into mature assets, unconventional plays, and deepwater frontiers, effective sand control remains a critical challenge. As reservoirs become more complex and economics tighter, the industry is shifting toward more-adaptive, data-informed, and targeted solutions. New research highlights innovative solutions that not only address technical limitations in existing designs but also enhance decision-making through digitalization and cross-disciplinary integration.

The three papers highlighted in this Technology Focus reflect this shift. Each explores a distinct facet of modern sand control: retrofitted screens for aging wells, predictive sanding mitigation using real-time modeling, and advanced completions designed for stacked, low-mobility reservoirs. Together, they underscore the industry’s move toward smarter, context-specific approaches that combine field data, simulation, and cross-disciplinary insights to improve reliability, reduce risk, and maximize recovery.

Through-tubing sand screens (TTSS) have become a preferred remedial solution for managing sand production in aging offshore wells. Yet, performance variability remains high, with over 40% of installations experiencing premature failure. Paper SPE 220610 presents an in-depth analysis of 125 TTSS installations across eastern Malaysia, identifying key design and operational factors that influence screen longevity.

Sand production because of excessive drawdown often results in costly interventions and deferred production. Paper SPE 220649 introduces a digital sand-management workflow that combines 1D geomechanical models, sanding-risk analysis, and wellbore simulation to compute a minimum tubinghead-pressure threshold, allowing operators to maintain sand-free flow without downhole pressure gauges. This workflow supports proactive sand control by integrating geomechanics with automated production modeling, a valuable step forward for digital oilfield implementations.

Developments in the lower Wilcox play in the Gulf of Mexico face a dual challenge: low-mobility, stacked reservoirs and a strong need for cost-effective, sand-tolerant completions. Paper SPE 220794 introduces a novel high-angle multi-frac completion system, engineered for deepwater environments with high rock strength (unconfined compressive strengths greater than 5,000 psi) where traditional gravel packs may not be feasible or necessary.

Three additional papers for recommended reading offer valuable perspectives on sand control. Paper SPE 220860 provides a field-based and modeling-supported analysis showing that sanding in weak formations can remain limited under low drawdown conditions. Paper SPE 221020 introduces a predictive methodology to identify sanding risk in horizontal wells by integrating geomechanics with operational data, enabling optimized perforation and drawdown strategies. Paper SPE 224059 details the successful use of an externally catalyzed resin for chemical sand consolidation in low-injectivity wells, offering a durable alternative where mechanical methods are less effective.

Collectively, these papers highlight the industry’s transition from standardized solutions to tailored, insight-driven sand control. Whether through improved screen design, geomechanical workflows, or next-generation completion systems, the path forward lies in integration of disciplines, technologies, and data.
