Abstract:
Through the reexamination and the stratigraphic corre- lation of nine exploration and development wells at Heilong- miao area,and in combination with the data of production test,formation testing and well logging,the characteristics of lithology,physical property,oil-bearing character and e- lectrical property of reservoirs of different types are summa- rized.According to the study on cross-plot and microscopic pore structure,the classification standard of reservoirs at the area is defined,and the reservoirs in the nine wells are clas- sified on the basis of the standard.The suggestions of pro- duction test and operation are presented,resulting in com- mercial oil production.
