Reservoir capacity of cambrian carbonate of foreslope facies in danzhai and sandu , eastern guizhou
2.
To sum up , the algae - rich carbonate of foreslope facies can form all kinds of bitumen - associated dissolved pores after experiencing burial dissolution , so it can have good capability of bearing oil and gas
3.
Algae - rich carbonate of cambrian is typical sediment of foreslope facies in sandu and danzhai , eastern guizhou province . after sediment , it experiences many changes of diagenetic environment , and takes place much diagenetic altercation , among which the biggest is salt water dolomilization , and then is compaction , recrystallization , pressure solution , organic dissolution , burial dolomilization , cementation and silicification
