反转构造的反转程度及其与油气聚集的关系
|
摘要
结合典型反转构造地震剖面,分析了断层型和褶皱型两类反转构造的反转程度,上下皆正断层型和向形褶皱型反转构造的反转程度轻微;上逆下正断层型和透镜形褶皱型反转构造的反转程度中等;上下皆逆断层型和背形褶皱型反转构造的反转程度强烈。分析了反转构造的反转程度与油气聚集的关系,处于轻微反转程度的上下皆正断层型反转和向形褶皱型反转,以及处于强烈反转程度的上下皆逆断层型反转和背形褶皱型反转不利于油气聚集;处于中等反转程度的上逆下正断层型反转和透镜形褶皱型反转类型有利于油气聚集成藏。
Based on the seismic profiles of typical reversal structures, reversal degrees of two types of reversal structures (fault type and fold type) were analyzed. Reversal degrees of the normal fault type up and down and the fold type with synformal cover were mild, that of the fault inversion with normal one upper and reverse one lower and the folded inversion with lens cover was moderate, and that of the fault inversion with reverse fault up and down and the folded inversion with antiformal cover was strong. The relationship between reversal degree of reversal structures and hydrocarbon accumulation was also studied, and a conclusion was drawn that the reversions with mild and strong reversal degrees did harm to hydrocarbon accumulation, and the reversion with moderate reversal degree was favorable to hydrocarbon accumulation and reservoir forming.
