摘要
多年来的重、磁力和地震资料表明，济阳坳陷车３潜山是油气有利聚集区，但由于地下地质情况复杂、地面条件差等原因，使早已提出的车５０井一直未能实施钻探。最近，在对新近施工的三维地震资料进行认真解释的基础上，选择构造有利位置，重新修正井位，钻探了车古２０井，并获得了工业油流。车古２０井的钻探成功，使地质工作者对车３潜山油气勘探又有一些新发现，尤其是对地层岩性、构造和油气藏特征等方面又增加了一些新认识。总结这些认识，将有利于在箕状断陷盆地陡坡带一侧寻找类似的潜山油气藏。
Gravitational, magnetic and seismic data showed that Che 3 buried hill is a favorable oil and
gas accumulation zone. However, Well Che 50 was located but not drilled because of complex
subsurface structure and bad ground condition. Based on careful interpretation of newly
gathered 3 D seismic data, Well Chegu 20 was drilled, and commercial oil flow obtained. This
brings us new knowledge of lithology, structure and reservoir property. Such ideas can help to
find out similar buried hill reservoir on steep slope of fault depression basin.
