【摘要】：大情字井油田是松辽盆地南部具有亿吨级储量规模的大型岩性油藏群。针对目前的资源状况及产能建设任务,通过总结深化成果认识,加强精细研究和基础研究,以成熟技术推广应用和新技术攻关相结合,以水平井开发试验和外围资源评价为依托,逐步突破技术瓶颈,实现主力层、潜力层和低品位资源的接替动用,稳步持续推进了产能建设工作。本次研究通过开展主力油层顶面古构造研究,指导优选了6个有利油气富集区带作为产能建设的重点目标区。在此基础上,通过精细刻画微构造,逐块落实油水界面,指导了主力油层扩边；并通过精细单砂体识别与相控储层特征参数研究,指导了岩性油藏区井位部署；同时,积极推进开发地震技术的应用,突破潜力层砂体识别的技术瓶颈,指导了青三段岩性油藏的逐步有效动用；通过深化油藏控制因素研究,进一步明确了外前缘复杂油水关系的控因,为井位部署提供依据。以此为基础,开展水平井开发试验,有效提高单井产能水平,推动低品位资源的效益开发。同时,紧密围绕外围潜力油层的评价成果,开辟生产试验区,建立注采井网,落实效益井位。在资源评价方面通过精细未动用资源分类评价方法,指导优选效益储量；根据未动用资源的分布特点,突出各层系主力油层评价,按层系、分小层重新梳理未动用资源的潜力分布,优化潜力目标的组合动用。
[Abstract]:Dazhengzjing Oilfield is a large lithologic reservoir group in the south of Songliao Basin with a reserve scale of 100 million tons. In view of the current resource situation and productivity construction task, intensive research and basic research have been strengthened through summing up and deepening the understanding of the achievements. With the combination of mature technology popularization and application and new technology tackling key problems, relying on horizontal well development test and peripheral resource evaluation, gradually breaking through the technical bottleneck and realizing the replacement and utilization of the main layer, potential layer and low grade resources, Through the study of paleotectonics on the top of the main reservoir, six favorable oil-gas enrichment zones were selected as the key target areas for productivity construction. Through the fine characterization of microstructures, the oil-water interface is implemented block by block, which guides the expansion of the main reservoir, and through the identification of the fine single sand body and the study of the characteristic parameters of the facies controlled reservoir, it guides the well location deployment in the lithologic oil reservoir area, at the same time, Actively promoting the application of seismic development technology, breaking through the technical bottleneck of sand body identification in potential layers, guiding the effective and gradual production of lithologic reservoirs of the third member of the Qing Dynasty, deepening the study of reservoir control factors, The controlling cause of complex oil-water relationship in the outer front edge is further clarified, which provides the basis for well location deployment. On this basis, horizontal well development tests are carried out to effectively improve the productivity level of single well and to promote the benefit development of low-grade resources. Closely surrounding the evaluation results of peripheral potential reservoirs, open up production test area, establish injection-production well pattern, and implement benefit well location. In the aspect of resource evaluation, we can guide the optimal selection of benefit reserves by means of fine classification and evaluation method of unproduced resources. According to the distribution characteristics of unexpended resources, this paper highlights the evaluation of the main reservoirs of each series, reorganizes the potential distribution of the unused resources in sub-layers according to the layers, and optimizes the combination and utilization of the potential targets.
