郑庄油区长6储层特征及其综合评价

据野外踏勘、钻井取心、录井和测井等资料，对研究区储层特征进行了综合研究。结果显示，该区长 6储层主要为成分成熟度较低的长石砂岩，其物源可能主要来自花岗岩区，部分来自沉积岩和变质岩区；沸石粒间溶孔和长石粒内溶孔是研究区储层的主要孔隙类型；储层物性影响因素主要包括其物质组成、沉积微相和成岩作用。该区储层可划分为4类，其中优质(Ⅰ类)和较好(Ⅱ类)储层主要分布在分流河道、河口坝微相或溶蚀孔隙发育的地区。研究成果为进一步制定合理的开发方案及剩余油挖潜等提供了基础依据。

The reservoir characteristics and comprehensive evaluation of Chang-6 formation in Zhengzhuang oil area

Aiming at the prospecting and developing situation and based on the field reconnaissance,drill core and logging,the reservoir of this area is mainly of arkose with poor compositional maturity,its provenance may be mainly from the granite region and a little may come from the sedimentary and metamorphic rock area,the main pores are intergranular dissolved pore of laumontite and intragranular dissolved pore of feldspar,the influencing factors of the reservoir physical property include material composition of ...
