构造演化对白家海凸起的油气成藏起着至关重要的作用。白家海凸起上除中-上三叠统小泉沟群在彩16井、彩31并局部范围内剥蚀殆尽外，其余地层都无缺失现象。利用厚度法较为准确地恢复了目的层面在不同地质历史时期的古构造形态，在平面上精细描述了白家海凸起的构造演化过程，并从构造发展史的角度分析了区内地层分布特征和油气成藏条件。
Tectonic evolution plays a crucial role in the hydrocarbon accumulation in the Baijian Sea. In addition to the middle-upper Triassic Xiaoquangou Group in the Baijai Sea, there is no missing phenomenon in the remaining strata, except for the denudation in the part of Cai-16 and Cai-31. Using the thickness method, the paleo-tectonic patterns of the target level in different geologic history periods are more accurately restored. The tectonic evolution of the Baijian uplift is described in detail in the plane. From the perspective of tectonic history, the distribution characteristics of the strata in the area are analyzed. Accumulation conditions.
