南川常压页岩气田勘探—储量—矿权一体化管理与实践

Management and practice of exploration–reserve–mining rights integration in Nanchuan normal-pressure shale gas

近年来,随着中国矿产资源管理改革的不断推进,石油公司原有的勘探程序和矿权维护制度必须随之调整。为此,提出了以全领域一体化研究、全方位一体化部署、全过程一体化运行理念为核心的勘探—储量—矿权一体化,以实现方案从单项优化向整体优化转变,达到“1+1+1>3”的效果。勘探—储量—矿权一体化主要体现在以下几个方面:(1)勘探发现是基础,储量评价是关键,探转采是目标,三者系统谋划、协同推进,才能保障石油公司综合利益最大化。(2)构建基于技术、经济、政策“三维一体”的大科研体系,用高质量科研夯实高质量油气发现和高效探转采的基础;构建基于“钻、压、试、采、销”5个关键环节的大部署体系,优化顶层设计,动态优化,实时调整,从源头提升部署质量;构建各类资源整合,统一调度运营的大运行体系,优化生产组织运行,确保提速提质提效。(3)践行勘探—储量—矿权一体化,需要树立观念认同、管理趋同、技术协同的“三同”理念。观念上凝聚矿权利益最大化的发展共识;管理上纵向贯通、横向联通,通过资源整合和流程优化,构建全过程关键节点管控机制,加快推动管理变革和效率提升;技术上持续深化基础研究,创新工艺技术迭代升级,实现高质量勘探突破和规模增储。勘探—储量—矿权一体化在川东南南川常压页岩气应用实践并获得显著效果,攻关形成了一批常压页岩气勘探开发关键技术,有效支撑了南川常压页岩气田的发现与建设,共新增页岩气探明地质储量1989.64×10^(8)m^(3),新立采矿权314.5971km^(2),累计新建页岩气产能超26×10^(8)m^(3),累计生产页岩气超65×10^(8)m^(3),建成中国首个大型且投入商业开发的常压页岩气田,实现矿权价值的高效转化,对中国非常规油气勘探和矿权管理具有积极作用。

In recent years,with the continuous advancement of mineral resources management reform in China,the original exploration procedures and mineral rights maintenance system of oil companies should be adjusted accordingly.As a result,the integration of exploration,reserve,and mineral rights with the core concept of“integrated research in all fields,integrated deployment in all aspects,and integrated operation in the whole process”has been proposed to realize the transformation from single-item scheme optimization to overall optimization and achieve the goal of“1+1+1>3”.The integration of exploration,reserve,and mining rights mainly includes the following aspects:(1)Exploration discovery is the foundation,reserve evaluation is the key task,and the transformation from exploration to production is the ultimate goal.The systematic planning and collaborative promotion of the above three factors should be conducted to ensure the maximum comprehensive benefits of oil companies.(2)A big scientific research system based on the“three-dimensional integration”of technology,economy and policy should be constructed to consolidate the foundation for high-quality oil and gas discovery and high-efficiency transformation from exploration to production through high-quality scientific research;An integrated deployment system based on five key links of“drilling,fracturing,testing,production and sale”should be established,and the quality of deployment should be improved from the source by optimizing top-level design,dynamically optimizing and conducting real-time adjustments;A large operation system of“integration of various types of resources,and unified scheduling and operation”should be constructed,and the organization and operation of production should be optimized to ensure the improvement of speed,quality,and efficiency.(3)In the practice of exploration-reserve-mining rights integration,the“three unified”concept of conceptual identity,management consistency and technical collaboration should be established.From the conceptual perspective,the development consensus of maximum mineral rights interests should be kept in mind;The vertical integration and horizontal connection of management should be implemented,and the control mechanism of key nodes throughout the entire process should be constructed by integrating resources and optimizing procedures,so as to accelerate management reform and efficiency enhancement;The basic technological research should continuously been deepened,and the technological iteration and upgrade should be innovated to achieve the high-quality exploration breakthroughs and reserve increase on a large scale.The integration of exploration,reserve,and mining rights has been practiced in Nanchuan normal-pressure shale gas field in Southeast Sichuan Basin,obtaining remarkable results and developing a number of key technologies for exploration and development of normal-pressure shale gas,which have effectively supported the discovery and construction of Nanchuan normal-pressure shale gas field,with the new addition proven shale gas geological reserves of 1989.64×10^(8) m^(3),new established mining rights area of 314.5971 km^(2),the cumulative new constructed shale gas production capacity of more than 26×10^(8) m^(3),and the cumulative shale gas production of more than 65×10^(8) m^(3).The application has enabled the construction of the first large-scale normal-pressure shale gas field in China that has been successfully commercialized.It realizes the high-efficiency transformation of the value of mineral rights,which has a positive role in unconventional oil and gas exploration and mineral rights management in China.
