摘要 

利用四川盆地磨溪地区12口井岩心、8口井成像测井资料、14口井的测井评价等资料,系统分析磨溪地区龙王庙组储层特征,划分了储层类型,探讨了储层形成主控因素,预测了优质储层展布。结果表明:1)川中磨溪地区龙王庙组储层主要岩石类型为中粗晶砂屑白云岩,储层中小洞发育,见到大量的构造缝和水平缝,整体表现为中低孔、中-高渗特征;2)龙王庙组储层类型可划分为溶蚀孔洞型、溶蚀孔隙型和基质孔隙型3种类型,其中高角度构造缝、水平缝、网状成岩缝和缝合线4种裂缝与3种储集类型形成整体连通的缝洞体系;3)优质储层主要在中细晶砂屑白云岩颗粒滩相中发育,颗粒滩后期经历3期岩溶作用,特别是表生期“顺层”溶蚀使溶蚀孔、洞型储层横向叠置连片,大面积分布,延伸5~20 km,井间连通性好,形成了孔洞发育的优质储层。

Abstract

Based on the data of 12 drilling cores, 8 imaging logs and 14 traditional logs in Moxi area, central Sichuan Basin, the major factors controlling the reservoir formation and favorable reservoir distribution are discussed in this paper through systematical analysis on the reservoir characteristics and types in Longwangmiao member. The Longwangmiao reservoirs primarily consist of medium-coarse grained dolomite, and dissolved pores are widely distributed in Moxi area, Sichuan Basin. Generally, the reservoirs are characterized by medium-high permeability, and can be divided into 3 reservoir types including dissolved hole type, dissolved pore type and matrix pore type. High-dip structural fractures, horizontal fractures, net-like diagenetic fractures and stylolites are also developed in Moxi area, which have close relationship with the 3 reservoir types and formed connected pore-system. The large-scale shore dolomite in Moxi area has experienced 3-stage karstification, and especially the surface dissolution stage has a significant influence on the large-scale hole-type reservoirs which extends over 5~20 km in horizontal. The good connectivity between wells is favorable for high-quality reservoirs in Sichuan Basin.
