摘要
根据构成复合圈闭封闭要素的组合关系 ,强调构造要素的封闭作用 ,将雅克拉断凸及其周缘地区的复合圈闭划分为 :复合盖层圈闭、构造—地层—岩性尖灭复合圈闭、构造断层遮挡复合圈闭、复合盖层—断层联合复合圈闭、构造—地层尖灭—复式储层复合圈闭。通过对雅克拉断凸及其周缘地区的地震解释和沿封闭面的构造编图 ,发现和识别了波斯坦北、雅西、哈北、老城等复合圈闭 。
According to the assembling relation among the sealing factors of forming combination trap, especially in consideration of the structural factor, the combination traps in Yakela fault arch and its surrounding areas can be divided into compounding caprock traps, structural-strati-graphic-lithologie pinchout combination traps, structural-fault screened combination traps, compounding caprock-fault combination traps and structural-stratigraphie pinchout-complex reservoir combination traps. Through the seismic interpretation and the structural mapping along seal-planes, some combination traps, such as north Bostan, west Yakela, Halahatang and Laochen combination traps have been found out and identified in Yakela fault arch and its surrounding areas. They will, be the important targets of hydrocarbon exploration in the near future.
