随着大牛地气田上古生界含气层系的勘探开发已进入中后期,奥陶系风化壳油气藏的油气资源丰富,这里将会成为今后的重点勘探目标。奥陶系风化壳是古生代早期加里东期的残余地层,强烈的岩浆活动剥蚀了它的地层,使其地质条件十分复杂,所以传统的识别评价方法已不能适应钻井新工艺的需求。面对勘探开发新挑战,需要采用新技术来对现场岩屑进行识别评价。
With the exploration and development of the Upper Paleozoic gas-bearing strata in the Daniudi gas field entering the middle and later stages, the oil and gas resources of the Ordovician weathering crust oil and gas reservoirs are abundant and will become the key exploration targets in the future. The Ordovician weathering crust is a remnant of the early Paleozoic Caledonian. The strong magmatic activity eroded its formation and made the geological conditions very complicated. Therefore, the traditional method of identification and evaluation can no longer meet the needs of new drilling technology. Faced with the new exploration and development challenges, the need for the use of new technologies to identify debris on-site evaluation.
