摘要
大庆萨南油田已进入特高含水开发阶段,油田开发面临储采失衡的矛盾日趋严重。为保证可持续开发,应用井震联合技术搞清过渡带四条带外扩区域构造储集层发育状况,进一步落实外扩区开发潜力。根据过渡带地区储集层发育特点,优选适合油水过渡带的合理注采井距、加密调整布井方式。在典型区块实施加密调整,增加可采储量19.6×10~4t,按照研究区开发模式,可在萨南油田西部过渡带四条带及外扩区3.98km^2推广应用,为过渡带外扩挖潜提供实践经验。
Sanan Oilfield in Daqing Area entered into the development stage of extra-high water content,the contradiction between the unbalanced oil storage and production was getting severe day by day.To ensure the sustainable oil development by means of logging-seismic combination,the development of structural reservoirs in the expanded area of the transition region was clarified for further determination of the development potential in the expanded area.According to the reservoir characteristics of research area,the feasible space of well pattern arrangement and infill adjustment was selected in the transition region of oil and water.The well pattern infill and adjustment are implemented in the typical area,the increase of recoverable reserves is 19.6×10~4 t,based on the development mode in the studied area,the technology can be popularized at 3.98 km^2 in the Fourth Zone of the transition region and expanded area,it provides practice experience for the potential tapping for expansion of the transition region.
