商741地区火成岩储层研究

Study on igneous reservoirs in Shang 741 area

通过分析商741地区钻井取心、测井及地震等相关资料,对火成岩储层裂缝的产状、张开度以及储层的孔隙度、渗透率、饱和度进行研究,并对储层进行详细地评价,明确了该区储层的地质特征及油气富集相带,划分出储层的有效裂缝带,确定了原油分布主要规律。此项研究对于指导该类型火成岩油藏的开发具有重要意义。

Through analyzing coring, logging and seismic data of Shang 741 area, this paper studies the occurrence and opening of fractures, as well as the porosity, permeability and saturation of igneous reservoirs. Reservoirs in this area are evaluated in detail, and geological characteristics and oil and gas accumulation zones have been made clear. The effective fracture zone has been defined in the reservoir, and the major law of oil distribution has been understood. This study is of highly importance to the development of this type of igneous reservoirs.
