摘要/Abstract

摘要： 新疆油田近年来启动了致密油的勘探与前期开发试验，在取得了一定成绩的同时，也在技术及管理领域进行了更多的实践与尝试。数年的致密油开发经验表明，致密油储层特性导致不能采用常规的开发思路对致密油资源进行开发，需要应用非常规的理念、方法和技术，需要采用地质工程一体化的理念来保障该类储层的勘探开发效果。通过在项目管理中的大量经验与实践，摸索出一套具有实践意义的方法，将地质工程一体化的核心应用于生产项目中，通过项目运行中不同阶段需求的差异性，推进不同环节的一体化工作，从而逐步提升致密油开发综合效益。在2015年，依照地质工程一体化的思路及方法，对新疆油田玛湖凹陷致密油进行了现场实践并获得显著成效。以致密油产量提高为中心，借助多个学科的无缝协同，利用地质条件与工程技术的紧密结合，通过管理与技术结合的手段，切实实现优选甜点、保障储层钻遇率及最优化压裂设计等动态决策，从而推动致密油的规模效益开发进程。在一体化思路指导下，深入推进精细化技术管理，建产部署及施工中的关键环节实现最佳把控，最终取得更佳的经济效益，同时摸索了工程技术服务新的模式，通过工程技术服务一体化总包模式，为中国陆地致密油开发建立了更为坚实的实践基础。

Abstract: In recent years, some exploration and early development tests of tight oil were satisfactorily carried out in Xinjiang Oilfield, and more practices and attempts were also implemented in technology and management. According to years of the tight oil development practices, it is found that tight oil reservoirs cannot be developed by conventional techniques due to the special reservoir properties. Instead, unconventional ideas, methods and technologies are required for unconventional reservoirs, and the model of geology-engineering integration is needed for ensuring the efficient exploration and development of such reservoirs. Accordingly, a set of practical methods was proposed after numerous practices in project management. Specifically, the core of geology-engineering integration is used in production projects. Based on various demands during different stages of project operation, the integration is followed in all steps. In this way, the composite benefits of tight oil development can be increased gradually. In 2015, based on the idea and procedure of geology-engineering integration, this set of methods was successfully applied in developing tight oil in the Mahu sag, Xinjiang Oilfield. For purpose of improving tight oil production, by means of seamless multi-discipline collaboration, combination of geological conditions and engineering technologies, and integration of management and technologies, dynamic decision-making was practically implemented in sweet-spot selection, assurance of reservoir drilling rate and optimal fracturing design, so as to promote the efficient and large-scale development of tight oil. Guided by the concept of “integration”, fine technical management was push forward, and the optimal control was realized in key links of production deployment and construction, uiming at better economic benefits. Moreover, a new model of engineering-technology service was worked out. By virtue of the engineeringtechnology service integration model, a more solid foundation was established for practical tight oil development in China onshore areas.

Key words: engineering-technology service integration, factory-like operation, fine technical management, Xinjiang Oilfield, geology-engineering integration, tight oil
