| 摘 要： | 异常高压的存在和油气分布关系密切。通过分析高邮凹陷北斜坡沙—花—瓦地区异常高压的形成机制，发现生烃增压、粘土矿物脱水增压是本区异常高压主要成因。异常高压分布范围在平面上受火成岩影响，只分布于沙埝内坡和花瓦内坡；纵向上受断层性质影响，只发育于吴堡期断层封挡好的层段。

Forming mechanism and distribution characteristics of overpressure in the first member of Funing Formation in Sha-Hua-Wa area of Gaoyou Sag |

| Abstract: | There is a close relationship between the existence of overpressure an d oil -gas distribution .By analyzing the formation mechanism of overpressure in the north slope of Sha -Hua-Wa area,the pressure of hydrocarbon generation and the dehydration of clay minerals were found to be the main causes of overpressure in this area .In the plane ,influenced by the igneous rocks ,the distribution range of overpressure is only distributed in Shanian slope and Hua -Wa slope .In ver-tical,affected by the nature of the faults ,the overpressure is only developed in the good blocked layers of Wubao fault . |
