Diagenesis and porosity evolution of carbonate reservoirs in Samandepe Gas Field，Turkmenistan
Online published: 2010-06-15
Based on field section measurement，we1l core observation and thin section identification，the diagenesis and porosity evolution of carbonate reservoirs in Samandepe Gas Field，Turkmenistan are synthetically studied．The destructive diageneses are mainly cementation，compaction-pressure solution，silication，anhydritization，sicilianitization and secondary mineral filling,while the constructive diageneses aYe mainly dolomitization，reerystallization，dissolution and fracturing，which results in the basic characteristics of the reservoir that has the combination of a variety of primary secondary porosity types such as organicvisceral pores，intergranular pores，intragranular pores，moldic pores， intercrystal pores，superlarge dissolved pores，dissolved caverns and fractures．On the basis of the reconstruction of diagenetic sequence，the restoration of porosity evolution respectively experienced the following phases：primary pores， residually primary pores，residually primary pores overlapping secondary pores，secondary pores overlapping primary pores·
