扶余油田是吉林油区开发较早的油田,目前大部分生产井没有自然产能,储层损害机理不明,现阶段采取水力压裂方式增产开采,增加开发成本,急需开展系统的储层损害机理研究,采取相应措施,提高油田开发效益。本文对该油田泉四段岩心进行岩性、物性分析,评价储层敏感性,对已有钻井液体系进行性能测试评价,分析储层损害机理,提出储层保护建议。
Fuyu Oilfield is an oilfield developed earlier in Jilin Oilfield. At present, most production wells have no natural capacity and the damage mechanism of reservoirs is unknown. At present, hydraulic fracturing is adopted to increase production and increase development costs, so systematic research on reservoir damage is urgently needed , Take corresponding measures to improve the efficiency of oilfield development. In this paper, the lithology and physical property of the Quaternary Member of the Oilfield are analyzed, the reservoir sensitivity is evaluated, the performance test of the existing drilling fluid system is evaluated, the reservoir damage mechanism is analyzed, and the reservoir protection suggestions are proposed.
