摘要：

在华北油田二连盆地的巴音都兰凹陷,按照寻找地层岩性油藏的新勘探思路,通过层序地层研究建立等时地层格架,根据构造与沉积综合研究确定有利勘探区块,依靠老井复查构建扇三角洲前缘砂体上倾尖灭岩性油藏成藏模式,发现了以岩性油藏为主的宝力格油田。在冀中坳陷,深化长洋淀潜山带成藏条件的研究,建立了"新生古储古堵"的潜山油藏成藏模式,使钻探获得新突破。

关键词: 巴音都兰凹陷, 长洋淀潜山带, 地层-岩性油藏, 华北油田

Abstract:

Huabei Oilfield Company has obtained many important achievements on the study and exploration of stratigraphic reservoirs in recent years.In the Bayindulan Sag of the Erlian Basin,guided by new exploration concept of searching for stratigraphic-lithologic reservoirs,the Baolige oilfield mainly composed of lithologic re-servoirs was finally discovered through establishing isochronous stratigraphic framework based on sequence stratigraphic study,determining potential exploration areas by comprehensive study of structure and sedimentation,establishing the pooling pattern of updip pinchout lithologic reservoir of fan delta front sand based on reviewing old well data.While in the Jizhong Depression,new breakthrough was made by deepening the study of reservoiring conditions in Changyangdian buried hills and establishing a new reservoiring pattern of "new-generating,old-accumulating and old-sealing".These two successful cases shed light on the future exploration practices in similar areas.

Key words: Bayindulan Sag, Changyangdian buried hill belt, stratigraphic-lithologic reservoir, Huabei oilfield
