Abstract: The shallow heavy oil reservoits in the overlap pinchout belts of the northwestern margin of Junggar Basin are of sandstone and sandy cctfiglomerate reservoirs characterized by minor diagencsis,poor cementation,good reservoir quality,erosion at upper part and overlap at lower part. Because oil reservoir rock Is unconsolidated and fragile,however,drilling core is less available using conventional techniques. It is difficult to establish the electric interpretation ptates with satisfaction. In this case,the approach of lithology interpretation in shallow heavy oil reservoirs was developed using a little data obtained from drilling,coring and various kinds of well logging techniques and was applied in 6 corewells and 301 producing wells to Qigu formation in the sixth region of District No.9 in Kaiamey oilfield to perform rock interpretation test. The results were obtained with more satisfaction.
