摘要

20世纪80年代中期以来,为了配合塔里木盆地的油气勘探,在塔里木盆地北部地区进行了大规模的地表油气化探普查和井中化探勘探工作。近20年油气化探的成果表明:在已知油气藏(田)上方有较好的化探异常显示,异常模式以环状或半环状晕为主;化探技术在未知区油气远景的预测评价、油气化探异常的圈定和评价等方面效果良好,许多化探异常经钻探后证实具有工业油气流;井中化探技术在现场随钻预测和发现井中的油气显示层方面亦取得了良好的效果。

Abstract

 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.
