| 摘 要： | :在研究大庆头台地区扶余油层微裂缝的基础上给出了无效缝的概念 ,从研究与无效缝形成有关的成岩作用入手 ,研究了成岩作用中的演化及无效缝的形成 ,论述了微裂缝形成期次、成藏期、次生矿物作用及无效缝形成期次的匹配关系。阐述了无效缝的形成机理、影响因素及在扶余油层中的分布特征。通过对无效缝的研究 ,揭示了无效缝的形成与发展对大庆头台地区扶余油层产油能力和储油能力的影响。本研究对特低渗透裂缝型油田的开发具有一定的指导意义。

| Abstract: | The authors have suggested the concept of the invalid fracture in this paper based on the study of micro fractures, in Fuyu reservoir of Toutai area of the Daqing. On the base of the diagenesis connecting with forming of the invalid fracture; we studied growth of microfractures during diagenesis and the formation of invalid fractures and described the relationship among the time of micro fracture formation, the time of the reservoir and authigenic mineral formation and the time of the invalid fractures formation. It pointed out the genetic causes, controlling factors of the invalid fractures, and the distribution characteristics in Fuyu reservoir. By studying of the invalid fractures, we demonstrate that the formation and development of the invalid fractures have affected the producing ability and reservation ability of Fuyu reservoir in Toutai area of Daqing. The study should have an important and leading significance for the development of the lowest permeability fracture reservoirs. |
