A study on surface and down-hole geochemical exploration techniques has been ca rried out in the Northern Tarim basin, and large scales of surface and down-hoe geochemical explorations have been conducted in this area since the middle of t he 1980s. Oil and gas geochemical exploration results of Tarim Basin accumulated in the past 20 years indicate that there exist obvious geochemical anomalies ov er the known oil/gas reservoirs, and the anomaly patterns are mainly ring-like halos or half rings. Geochemcal exploration in the unknown areas also achieved g ood effects in the aspects of prediction of the prospects, delineation of geoche mical anomalies and evaluation of geochemical evaluation. Quite a lot of geochem ical anomalies delineated in the unknown area have been verified with commercial oil/gas flows by drillings. Down-hole geochemical exploration shows good explo ration results in the aspects of in-situ prediction and identification of oil/g as show layers.
