弗里奥(Frio)组的渐新世哈克贝里地层的深水砂岩储集了大量的油气,至今仍为得克萨斯东南部最重要的深部勘探目标之一。事实上,哈克贝里层含有两个烃类远景区带。偏上的远景区带相对较浅,富集石油,并位于深水沉积的上倾边缘附近。在该远景区带中,有些油 The deep-water sandstone of the Frio Formation in the Oligocene Hakeburi formation accumulates a large amount of oil and gas and remains one of the most important deep-water exploration targets in southeastern Texas. In fact, the Huckberry Layer contains two hydrocarbon vistas. The upper prospect is relatively shallow, oil-rich and is located near the up-dip margin of deep-water sediments. In this long zone, some oil
