【摘要】：针对曹妃甸Main油藏辫状河储层分布规律认识不清,导致中东侧过渡带和中西部纯油区开发程度差异大的问题,利用Miall储层构型研究思路,分析储层展布规律。在储层研究基础上,总结了储层开发规律和剩余油分布特点,研究了井型、井网、水平段最优长度等影响开发策略的关键因素,提出了东西两侧差异化的开发模式:东部过渡带井控程度低、剩余油富集区域部署水平调整井,以不规则井网模式开发;中西部纯油区采用86~87°斜穿储层水平井注水模式开发;主、次辫流带分别部署注采井网,提高了储量动用程度,改善了开发效果。先期实施的调整井有力验证了差异化开发模式的合理性。该研究成果对类似油藏的开发调整具有借鉴和指导意义。
[Abstract]:Aiming at the problem that the distribution of braided river reservoir in Main reservoir of Caofeidian is not clear, which leads to the difference of development degree between the middle and east transitional zone and the central and western pure oil area, the distribution law of reservoir distribution is analyzed by using the research ideas of Miall reservoir configuration. On the basis of reservoir research, this paper summarizes the rules of reservoir development and the distribution characteristics of remaining oil, and studies the key factors affecting the development strategy, such as well type, well pattern, and optimal length of horizontal section, etc. The development model of the east and west two sides is put forward: the eastern transitional zone has low well control degree, the level adjustment well is deployed in the remaining oil enrichment area, and the pattern of irregular well pattern is used to develop; In the central and western pure oil area, the injection pattern of 86 ~ (87 掳) diagonal horizontal well is adopted, and the main and secondary braided flow zones respectively deploy injection-production well pattern, which improves the level of reserve production and improves the development effect. The adjustment well implemented in advance has proved the rationality of the differentiated development model. The research results have reference and guidance significance for the development and adjustment of similar reservoirs.
