Abstract:

Shenping oilfield is situated in south end extension of Xujiaweizi nosing structure, Sanzhao sag, central depression, Songliao basin, with Putaohua formation to be the major reservoir. After a long term drilling development, injection-extraction adjustment and water-injection structural adjustment, those blocks with good reservoir are now in late development stage with a little potential. The northern Shenping basin is a virgin, low extent in drilling and poor in Putaohua reservoir, largely occurring as water layer or dry layer, as well as Fuyu reservoir. It is difficult to develop this block. This paper studies the oil-bearing features with results that it is of potential to find oil-bearing blocks in the northern Shenping basin.

Key words: Shenping oilfield, oil-bearing features, favorable oil-bearing block
