    摘要:

    陆相油藏是中国油藏开发的主要对象,由于其自身特点,该类油藏在开发过程中面临多种挑战,并且不同开发阶段面临的主要矛盾各异,因此,以动力递进主导的全生命周期全要素协同开发是提高该类油藏开发效果的理论基础。在研究系统动力协同递进开发规律的基础上,提出油藏开发动力协同递进开发原理,认为层系细分和井网适应是油藏开发的主要引导力,介质超越是油藏开发的主要推动力。借助室内实验和数值模拟手段,就介质超越提出六大油藏开发驱替介质序列和五种油藏开发驱替介质动力协同递进典型组合。在此基础上,结合介质超越、层系细分与井网适应等油藏开发六大要素,应用金字塔原理,建立了油藏开发系统全要素协同开发宝塔图版,直观形象地阐明了油藏全生命周期动力协同递进开发模式,2010年依据该图版,按照正常接替递进典型组合模式,在柳赞北区实施气驱开发,阶段末采出程度达到23.4%,在水驱的基础上提高了14.8%。

    Abstract:

    The continental reservoirs are major development objects in China. There are a variety of challenges during this types of reservoirs development and the principle contradictions vary at different development stages. Therefore the theoretical basis of developing the reservoirs with high efficiency is to regard the development process as a whole life cycle with a priority to dynamic progressive. Based on the research on systematic dynamic synergetic progressive development rule,the principle of the dynamic synergetic progressive development was proposed,with the major leading force as the subdivision of series of strata and the adaptation of well patterns,and the driving force as the media transcendence. Six sequences on displacement media and five classical combinations about its progressive capacity were optimized through library experiment and numerical simulation. Based on these,combining with six development elements on the media transcendence,subdivision of series of strata,and adaptation of well patterns,etc.,a pagoda-like chart about all the development elements by pyramid principle was established,which illuminates the synergetic development pattern of all the development elements in whole life-cycle dominated by dynamic progress. In 2010,according to the chart and normal replacement progressive typical combination model,the development of gas flooding was implemented in north Liuzan block. The percentage recovery of OOIP at the end of the stage reached 23.4%,which increased by 14.8% than that of water flooding.
