洪浩尔舒特是近年来二连新区勘探高速度、快节奏取得重要突破的一个凹陷。研究表明 ,该凹陷具有阿尔善组、腾一段两套有效烃源岩 ,阿尔善组、腾一段是主要储油层系 ,腾二段是重要含油层系 ,斜坡带上的鼻状构造、洼中的反转背斜、陡带断鼻是油气聚集的主要场所。储油岩主要为扇三角洲、水下扇沉积的岩屑砂岩、含砾砂岩 ,富含火山碎屑成分 ,凝灰质、高岭石粘土含量高 ,储层物性差 ,油层易受污染 ,油层保护是获得油气勘探突破的重要保障 ,压裂改造是获得较高产量的重要手段
Hong Hao Seoul Shute Erlian New District in recent years the exploration of high speed, fast paced made a major breakthrough in a depression. The study shows that the sag has two sets of effective source rocks, namely, Aershan Formation and Teng-1 Member. The Aershan Formation and Teng-1 Member are the major reservoir systems. The Teng-2 Member is an important oil-bearing formation and a nose-like structure on the slope. The reverse anticline, steep cut nose is the main place for oil and gas accumulation. The oil-bearing rocks are mainly composed of fan-shaped delta, subaqueous fan-deposited lithic sandstone, pebbly sandstone, volcaniclastic components, tuffaceous kaolinite, high clay content, poor reservoir properties, reservoir susceptibility to contamination, reservoir protection Is to obtain an important guarantee for oil and gas exploration breakthrough, fracturing is an important means to obtain higher yields
