摘要
欢喜岭油田是开发近40年的老油田,最近几年上报的储量区块中主要为深层、稠油、薄层油藏,发现的优质储量主要为复杂断块油藏。在对这类油藏的研究中,应该从油藏的基本特征入手,分析复杂断块油藏制约因素,制定勘探开发一体化的思路,最大限度以及最快速度挖掘油藏潜力并尽快建产。利用VSP测井技术,测井资料和地震资料相结合,精细落实构造及储层发育情况,并利用蜘蛛网图研究该区隔层发育情况,利用隔夹层研究技术确定储层封堵性,根据勘探开发一体化思路,进行井网优化设计,按照分层注水开发的油藏整体开发思路进行井位部署。在部署探井的同时注重开发井网和后期注水调整井网的优化,在开发井网部署时,充分考虑储量有效动用,利用隔夹层发育特征来部署直井和水平井,从而实现储量向产量的快速转化。
Huanxiling oilfield is an old one developed nearly 40 years.Recently reported reserves have been accumulated in the deep,heavy oil and thin oil reservoirs mainly,and the high quality reserves were found in the complex fault block reservoir.In the study of this type of oil reservoir,influencing factors of the com- plex fault block reservoir should be analyzed according to the basic features of the oil reservoir.Idea of inte- gration of exploration and development should be formulated and then the potential of the oil reservoir may be tapped in the maximum limit and at fastest speed.The development degree of structure and reservoir may be made clear using VSP logging technology based on the logging data and seismic data.The development degree of interlayer should be known through spider diagram.Interlayer research techniques may be applied to determining sealing property of the reservoir.Well pattern design may be optimized and the wells should be deployed according to the integrated layered waterflood development.When the exploratory wells are deployed, well pattern of development and later injection modification should be optimized at the same time.The re- serves should be produced effectively when the development pattern is deployed.Vertical wells and horizontal wells may be deployed according to the development features of the interlayers so as to realize the rapid transformation of reserves to production.
