页岩气开发技术装备自主化研究进展与展望

对国内外页岩气开发装备作了概述,着重阐述了国内在页岩气开发技术装备自主化研究方面的进展。国外页岩气水平井开发核心技术装备包括智能化测量工具、井下动力钻具、旋转导向工具、地质导向工具等;压裂增产技术主要包含水力喷射工具、多层同时压裂工具等。国内钻机、压裂机组技术水平可满足丛式、水平井等工艺要求,封隔器、滑套等井下工具已初步实现国产化,测井设备可靠性、时效性及测量精度与国外先进水平差距较大,随钻测井(LWD)工具、旋转导向工具等几乎全部依赖进口。本文提出了页岩气开发装备自主化研究的攻关方向和发展趋势,建议研制适合不同钻井深度和资源条件的专用钻机,解决页岩气长水平段钻井难度大、周期长等问题的井下提速和导向工具,高分子材料井下封隔器等压裂改造工具,和适应未来大规模产量下的合理组织技术及后期完整配套采气工艺装备。

Progress and prospects of autonomization of technology and equipment for shale gas development

This paper outlines domestic and international situations for shale gas developing equipment, especially elaborates the autonomization progress in China, discusses the intelligent measurement tool, downhole motor, rotary steering tool, geo-steering tool for shale gas horizontal wells drilling, hydraulic jet tools, multilevel fracturing tools for fracturing stimulation in aboard, and drilling rigs, fracturing equipment, packer and sliding bush, logging equipment, LWD and rotary steering tool domestically. We suggest developing special drill rigs which are suitable for different geology and resource conditions, down-hole speeding tools, directional tools, and fracturing tools made of high polymer materials for mass production of shale gas in the future.
