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 oilfield developed for nearly 40 years. The reserves reported in recent years mainly consist of deep, heavy oil and thin-layer reservoirs, and the high-quality reserves discovered are mainly complex fault-block reservoirs. In the study of such reservoirs, we should start from the basic characteristics of the reservoir, analyze the constraints of complex fault block reservoirs, formulate an integrated exploration and development train of thought, maximize and maximize the potential of the reservoir and excavation as soon as possible . Using VSP logging technology, well logging data and seismic data, the structure and reservoir development are meticulously implemented. The spider web is used to study the development of the interlayer in this area, and the plugging layer research technique is used to determine the reservoir sealing properties. According to Exploration and development of integrated ideas, the well pattern optimization design, according to stratified waterflooding development of the overall reservoir development well position deployment. In the deployment of exploration wells at the same time pay attention to the development of well and post-injection water to adjust the well network optimization, in the development of well network deployment, give full consideration to the effective use of reserves, the use of inter-mesa development features to deploy vertical wells and horizontal wells in order to achieve reserves to production quickly Conversion.
