XX开发区XX组烃源岩主要来自齐家-古龙凹陷青一段黑色泥岩,储集层分布零散且物性差,研究表明油沿油源断裂作为垂向运移的主要输导通道向高部位运聚,形成以构造-岩性为主油气圈闭。由于远离油源区、砂体等因素的影响,限制了平面的成藏范围及成藏规模。综合生储盖特征,含油有利区主要聚集在有效排烃范围油源断裂附近。
The XX Group source rocks of the XX Development Zone are mainly derived from the Qinglian black mudstone in the Qijia-Gulong Sag with scattered and poorly distributed reservoirs. The study shows that oil fractures act as the main transport channel for vertical migration to the upper parts Poly, formed to structure - lithology-based oil and gas trap. Due to the influence of the distance from the oil source area and the sand body, the extent of the plane accumulation and the scale of reservoir formation are limited. Based on the characteristics of the source and reservoir caprocks, the oil-bearing favorable areas mainly gather near the oil source fracture in the effective hydrocarbon expulsion range.
