摘    要:从粒度、泥质及黏土矿物、孔隙结构、束缚水饱和度、导电矿物、薄互层等6方面对珠江口盆地琼海凸起文昌A、B油田低阻成因机理进行系统研究。通过低阻储层段与正常储层段各方面的对比分析,得出研究区岩性细、泥质重、细一微孔隙体积比例高,进而导致高束缚水饱和度是影响文昌A、 B油田ZJl段储层低阻的重要因素,为后续低阻储层的定性识别和定量解释提供依据。

关 键 词:文昌A、B油田  低阻储层  成因机理  海南

Abstract:The authors studied the genetic mechanism of low-resistivity from particle size,mud and clay minerals, pore structure,irreducible water saturation,conductive minerals and thin interbed in Wenchang A and B oilfields of Qionghai uplift in Pearl River Mouth Basin.Comparing the low-resistivity reservoir and normal reservoir, the authors found that the studied area was characterized by fine lithology,heavy mud and high volume ratio of finemicro pores,and then led to high irreducible water saturation,which was th...
Keywords:Wenchang A and B oilfields  low-resistivity reservoir  genetic mechanism  Hainan
