越来越多的油气田勘探开发实践表明，“地质工程一体化是实现复杂油气藏效益勘探开发的必由之路”。总结了地质工程一体化技术的研究和应用现状，剖析了其发展过程、实现思路，列举了国内外典型应用实例，梳理了地质工程一体化攻关方向。分析发现，北美地区以及国内西南油气田、浙江油气田、塔里木油气田、新疆油气田、长庆油田、大港油田、吉林油田等油田区块已开展了地质工程一体化应用实践；BHGE、斯伦贝谢、哈里伯顿等公司也积极与油田合作，提供地质工程一体化服务及软件平台。长宁页岩气示范区通过实施地质工程一体化，日产气量提高127%、钻遇率提高1.8倍、钻井周期缩短53.3%，开发井各生产指标都超过了设计指标。我国地质工程一体化急需攻关方向包括：①形成统一的地质工程一体化思想；②建立健全地质工程一体化运行机制；③强化地质工程一体化考核；④加快页岩气地质工程一体化开发技术突破；⑤加强地质力学在地质工程一体化中的应用；⑥培养地质工程一体化复合型人才。

More and more practices of oil and gas field exploration and development indicate that geology-engineering integration is the only way to realize the benefit exploration and development of complex oil and gas reservoirs. In this paper, the research and application status of geology-engineering integration technology was summarized and its development process and implementation ideas were analysed. Domestic and foreign application cases were described. In addition, the research directions of geology-engineering integration were pointed out. It is indicated that geology-engineering integration has been practically applied in the North America and China’s Southwest Oil & Gasfield, Zhejiang Oilfield, Tarim Oilfield, Xinjiang Oilfield, Changqing Oilfield, Dagang Oilfield and Jilin Oilfield, and BHGE, Schlumberger and Halliburton have been actively cooperating with each oilfield to provide the services and software platforms for geology-engineering integration. After the implementation of geology-engineering integration in Changning Shale Gas Demonstration Area, the daily gas production is increased by 127%, the drilling rate is increased by 180%, the drilling cycle is shorted by 53.3% and all production performances of development wells exceed the expected indicators. As for domestic geology-engineering integration, it is in urgent to carry out the researches in the following aspects. First, form the unified idea of geology-engineering integration. Second, set up and improve the operation mechanism of geology-engineering integration. Third, strengthen the performance evaluation of geology-engineering integration. Fourth, speed up the technological breakthrough in the geology-engineering integrated development of shale gas. Fifth, strengthen the application of geomechanics in geology-engineering integration. Sixth, train inter-disciplinary talents in the field of geology-engineering integration.
