根据台湾石油地质学家多年来的工作结果,台湾西部油气田的形成主要受岩性(砂体)、背斜和断层控制,其次为地层不整合因素.在台西坳陷的西、北部和台南盆地的西、北部,油气田的分布是由构造挤压、埋藏压实和地温差异引起的油气运移方向所决定的.下一步勘探区的选择应为已知含油气背斜长轴方向的外延部位,深部木山组及其以下层位(包括白垩系),扭性断层的上升盘,基底高及其周围的地层不整合、地层尖灭区.
According to the results of Taiwan petroleum geologists over the years, formation of oil and gas fields in western Taiwan is mainly controlled by lithology (sand bodies), anticlines and faults, followed by unconformities in the strata. In the western and northern parts of Taiwan and West Taiwan, The distribution of oil and gas fields in the west and north of the basin is determined by the direction of hydrocarbon migration caused by tectonic compression, burial compaction and the difference in ground temperature. Next, the exploration area should be selected as the extension of the known long axis of the anticavoid Site, the deep Moushan Formation and its sub-layers (including the Cretaceous), the ascending disk of the torsional fault, the basement height and the unconformity of the strata around it, and the stratiform pinch out area.
