在深入研究大庆油田陆相沉积油层地质特点的基础上，结合油田二十六年的注水开发实践和经验，初步探讨了陆相砂岩大油田的开发模式。油田开发过程中，坚持了应用沉积相理论，不断认识油层；多次布井，充分发挥各类油层作用；分阶段制定开发政策，合理保持和充分利用驱动能量；总结生产规律，掌握油田稳产趋势；加强实验研究，努力提高油田采收率；适应分层调整要求，完善分层开采工艺；按照稳产要求，不断发展地面工程技术等七项基本作法，取得了好的油田开发效果。从油田地质研究和开发理论上总结出的这些认识，对陆相砂岩油田的注水开发具有普遍意义。
Based on the in-depth study of the geologic characteristics of the continental sedimentary reservoirs in Daqing Oilfield and the twenty-six years of practice in oilfield waterflood development and experiences, the development mode of the large oilfields in continental sandstone is discussed. Oilfield development process, adhere to the application of sedimentary facies theory, continue to recognize the reservoir; well cloth several times, give full play to the role of various reservoirs; development of development policies in phases to reasonably maintain and make full use of the driving energy; summary of production rules, master the trend of stable production of oil ; To strengthen experimental research, and strive to improve oil recovery; adapt to the requirements of stratification adjustment, improve the stratified mining process; in accordance with the stable production requirements, the continuous development of ground engineering technology and other seven basic practices, and achieved good oil field development results. These understandings summarized from the theories of oilfield geology research and development have universal meaning for waterflooding of continental sandstone oilfields.
