摘要/Abstract

摘要： 目前，油气资源劣质化已成为油气勘探开发所面临的共性问题，吉林油田尤为突出。受低油价与资源品质变差的双重冲击，效益建产难度越来越大，产建规模大幅萎缩。为应对上述挑战，借鉴北美致密油气开发的成功经验，提出了“提产量、提采出程度、降投资、降成本”的策略，在吉林油田新立Ⅲ区块常规低渗透油藏应用地质工程一体化理念，形成了集约化建产模式，实践了油藏体积改造、非常规能量补充、工厂化作业等一系列非常规技术及做法。与常规建产模式相比，在提高产量与缝控储量、降低投资与运行成本方面，取得了突出效果，并在致密油开发中得到进一步推广。实践表明，在充分重新认识低渗透油藏潜力与技术体系的基础上，实施地质工程一体化、非常规技术的合理应用，是目前乃至今后实现效益建产的必然选择。

Abstract: At present, low-quality resource is a common issue for oil and gas exploration and development in all oilfields, especially the Jilin oilfield. Due to the dual effect of low oil price and down-grading resource quality, beneficial productivity construction is more and more difficult while available productivity scale shrinks significantly. In order to deal with these challenges, the strategy of “enhancing the production and recovery percent, and reducing the investment and cost” was proposed in reference to the successful tight oil and gas development in North America. The concept of geology and engineering integration was applied to the conventional low-permeability oil reservoirs in the Xinli III block, the Jilin oilfield, and the intensive productivity construction mode was established. Moreover, a series of unconventional technologies and practices were actually used in the Jilin oilfield, including reservoir volume fracturing, unconventional energy supplement and factory-like operation. Compared with the conventional productivity construction mode, the intensive productivity construction mode is more remarkable in enhanding the production and fracture-controlled reserves and reducing the investment and operation costs. This mode is further promoted in the development of tight oil. It is indicated that, after the potential and technical systems of low-permeability oil reservoirs are re-understood sufficiently, the rational application of geology and engineering integration and unconventional technologies is inevitable for the beneficial productivity construction currently and even in the future.
