摘要:

应用测井资料和铸体薄片、扫描电镜、X-衍射、粒度分析、压汞等化验分析资料综合研究了安塞油田沿25区块长6储层的特低渗透成因和影响因素,并评价了储层储集性能。分析表明,该区块储层物性总体较差,发育粒间孔、溶蚀孔,孔隙结构类型属小孔隙、微细喉道型。其特低渗透成因主要受沉积作用和成岩作用的共同影响,具体表现为:不同沉积微相储层的物性差异较大,软组织含量大、粒度细和成分成熟度较低是造成储层特低渗透特征的主要原因。同时成岩压实、胶结作用使得储层的孔隙度、渗透性进一步减小、变差,而溶蚀作用和成岩缝的产生又在很大程度上改善了储层的特低渗透特征。根据物性和孔隙结构参数分析,将研究区储集岩分为3类,水下分流河道与河口坝砂体是主要储层分布相带。

Abstract:

The origin of extra low-permeability and influential factors of Chang6 reservoir in the Yan25 area of Ansai Oil Field are studied synthetically through using the log information, testing and analytical information such as Casting section, scanning electron microscope, X diffraction, grain size analysis and mercury penetration et al. and then, the reservoir is evaluated. The results show that accumulation properties are worse, the reservoir mainly develops intergranular pore and emposieu, and pore structure types are fine pore and microscopic throat. Sedimentation and diagenesis have impacted on the origins of extra low-permeability together, such as accumulation properties are various in the different Sedimentary microfacies. The great content of low-energy component, fine grade and the low compositional maturity are the main reasons that cause the extra low-permeability. Compaction and cementation have decreased the porosity, then the permeability have become worse. However, denudation and fractures have improved the extra low-permeability characteristics to some great extent. According to the analysis of properties and pore structure parameters, the reservoir is classified into 3 classes, subsea river channel and mouth bar sand body are the main distributed facies belt of the reservoir.

Key words: Origin of extra low-permeability    Diagenesis    Reservoir evaluation    Chang 6 reservoir    Ansai oil field.
