摘要
随着全球能源需求持续增长,深地油气勘探开发已成为保障国家能源安全的重要战略方向。文章以中国首口万米科学探索井——深地塔科1井为研究对象,系统分析了深地测井技术在超高温超高压环境下安全高效采集面临的重大挑战。对比国内外先进测井技术服务企业技术指标,中国在高张力动力系统、耐高温材料和高速数据传输等领域无法完全满足深地塔科1井测井采集需求。在此基础上,通过数值模拟、新材料研发和破坏性试验等手段,开展了13000m超高强度特制电缆、15000m高张力动力系统、230℃/180MPa小直径测井仪器和特深层复杂条件直推测井工艺等国产化自主研发,并通过“实验室—标准井—实钻井”三级试验验证装备性能指标,最终成功实现深地塔科1井9000m以深9趟测井资料安全高效采集,最大测井深度达10870m,最高测井温度207℃,测井一次下井成功率100%,为中国深地油气勘探开发提供了强有力的技术支撑。同时总结测井技术研发典型做法,为工程技术关键核心装备升级提供借鉴。
With the sustained increase of global energy demand,deep-earth oil and gas exploration and development has emerged as a pivotal strategic priority for ensuring national energy security.Taking the first 10,000-m scientific exploration well in China,Well Shendi Take 1,as a study object,major technical challenges hindering safe and high-efficiency logging data acquisition in ultra-high temperature and ultra-high pressure environments have systematically been analyzed.The comparison of technical specifications between domestic and foreign advanced logging service providers indicates that the domestic logging technologies insufficiently meet the operational demands of the Well Shendi Take 1 in terms of high-tension power system,high-temperature material,and high-speed data transmission.In order to bridge these gaps,a series of methods such as numerical simulation,advanced material research,and destructive test have been applied to independently research and develop domestic technologies,including a 13,000-m ultra-high strength specialized cable,a 15,000-m high-tension power system,a 230℃/180MPa small-diameter logging tool and vertical logging technique optimized for ultradeep complex formations.The equipment performance indicators have rigorously been validated by a three-phase test involving“laboratory testing,standard well trial,and actual well application”,facilitating the safe and high-efficiency logging data acquisition in the Well Shendi Take 1(nine trips at depths exceeding 9,000m),with a maximum logging depth of 10,870m,a peak operating temperature of 207℃,and a 100%success rate of single-trip logging operation,which provide powerful technical support for deep-earth petroleum exploration.Furthermore,the typical practices of well logging technological research and development have been summarized,providing reference for future upgrade of key core engineering equipment.
