裂缝型储层指水平井在水平段钻进过程中,录井显示活跃、测井响应特征明显,具有一定长度的裂缝油层。三维地震显示,红河油田存在多条裂缝带,主要以北西—南东走向为主,一般为高角度垂向裂缝。岩心资料显示,长8、长9油层组裂缝均为高角度垂向裂缝。实际试采数据表明裂缝井试采数据较好,有较强的产能空间,但在实际开发中,裂缝井段经常出现井漏、溢流和活跃的槽面显示,为更好地满足裂缝型储层开发的需要有必要对裂缝型储层特征及产能解释评价进行精细研究。
Fractured reservoirs are horizontal wells that show well logging during horizontal drilling. Logging features are obvious and fractured reservoirs have a certain length. Three-dimensional seismic data show that there are a number of fractures in the Honghe oilfield, mainly dominated by NW-SW trends and are generally high-angle vertical fractures. Core data show that the fractures of Chang 8 and Chang 9 reservoirs are all high-angle vertical fractures. The actual test data show that the fractured well has good test production data and strong production capacity. However, in the actual development, the well, leakage and active surface of the fractured well often appear. In order to better meet the fracture type Necessity of reservoir development It is necessary to conduct a detailed study on the characteristics and interpretation of fractured reservoirs.
