摘　　要：濮城油田文 51断块区是一个典型的多油层非均质油藏 ,油气分布受构造—岩性双重因素控制。断块区内地质构造复杂、储层非均质和井况损坏严重 ,导致了地质认识程度低 ,开发井网不完善 ,严重影响了区块的开发效果。为了改善区块开发水平 ,及时进行了构造落实、沉积微相、储层非均质性和剩余油分布等方面的研究。通过部署双靶定向井、侧钻井、更新井及实施油水井补孔、调驱、恢复等工艺技术 ,有效地挖潜了剩余油 ,实现了区块长期稳产 。The fault-block W51 is a typical multizones hetergenous reservoir,the oil-gas distribution is controlled by structure and lithology .The gelogical structure of the fault block is complex ,the heterogeneity of the storage zone and the damage of hole condition are severe ,these all lead to the low degree of geological knowledge and uncompleted develop pattern ,which influents the whole development effects .In order to impress the degreement of block development ,we study the structure,deposition,heterogeneity and the remain oil distribution law and dispose controlled directional well,side-tracking well,renew well,and take advantage of the technology of perforation ,profile control flooding,renew etc ,to tap production potential effectively .The long steady production is gained,and the better social economic benifit is gained too.
