开发地震技术是勘探地震技术向油田开发阶段的延伸。开发阶段地震技术主要用于提高分辨率、提高储层描述和烃类检测精度、建立精细三维油气藏模型。其难点是目前的地震分辨率难以满足开发需要,利用常规地震资料进行流体预测的精度较低,基础研究有待加强,地球物理和油藏工程的一体化尚处于探索阶段。针对油田开发开展了高精度三维、高密度、储层精细描述等技术研究与应用,但应用效果与地质需求仍有差距,地震预测精度亟待提高。为此,对未来开发地震发展方向进行了探讨,并提出了建立相对稳定的研究团队,推动地震—油藏一体化平台建设以及人员和软件平台的整合;强调生产时效性和技术创新性并重,在着力推广成熟技术的同时,组织力量攻关瓶颈技术;以试验区项目运作带动技术系列、技术流程和技术规范的形成及推广,为开发阶段大面积应用地震技术奠定基础等发展建议。
Developing seismic technology is an extension of exploration and seismic technology to oilfield development. Development stage Seismic techniques are mainly used to improve the resolution, improve the reservoir description and hydrocarbon detection accuracy, and establish a fine three-dimensional reservoir model. The difficulty is that the current seismic resolution is difficult to meet the development needs, the accuracy of fluid prediction using conventional seismic data is low, basic research needs to be strengthened, and the integration of geophysics and reservoir engineering is still under exploration. According to the research and application of high-precision three-dimensional, high-density and fine reservoir description for oilfield development, there is still a gap between application effect and geological demand, and the accuracy of earthquake prediction needs to be improved urgently. Therefore, the development direction of seismic exploration in the future is discussed, and a relatively stable research team is proposed to promote the integration of seismic-reservoir integration platform and personnel and software platform. Emphasis is placed on equal emphasis on production timeliness and technical innovation, While endeavoring to popularize the mature technologies, the organization forces tackled the bottleneck technology. The operation and development of the project areas in the pilot area led to the formation and promotion of technical series, technical procedures and technical specifications, and laid the foundation for the application of large-scale seismic technology in the development stage.
