Abstract:In order to study the oil and gas distribution of the Lower Cretaceous Damoguaihe Formation in Sudeerte area,Hailar Basin,on the basis of the mechanism of oil and gas transfer in deep oil and gas “transfer station” and the prediction method of favorable position.By determining the distribution area of oil and gas “transfer station” in the Lower Cretaceous Nantun Formation and the unsealed area of mudstone cap rock at the top of the Nantun Formation, the oil and gas “transfer station” from the Nantun Formation to the Damoguaihe Formation is determined.Combined with transporting fault transporting oil and gas favorable position,this paper uses the prediction method of favorable position of oil and gas transfer from deep oil and gas “transfer station” to shallow oil and gas,the favorable position of oil and gas transfer from the Nantun Formation to the Damoguaihe Formation in Sudeerte area is predicted.The results show that: The favorable parts for oil and gas transfer from the Nantun Formation to the Damoguaihe Formation in Sudeerte area are mainly distributed in the central area,and small amounts are distributed in the northwest and northeast regions,which controls the oil and gas accumulation and distribution of the Damoguaihe Formation in Sudeerte area.The favorable position of oil and gas transfer from the Nantun Formation to the Damoguaihe Formation or the undrilled position nearby should be the favorable position for the next oil and gas exploration of the Damoguaihe Formation in this area at present.
