摘　　要：盐间泥岩裂缝油气藏是一种特殊的油气藏类型。东濮凹陷文留地区沙四段、沙三段广泛发育盐—泥层,其中Es32亚段是盐间泥岩裂缝油气藏富集区。文留地区盐间泥岩裂缝油气藏的储层亦为烃源岩,且油气的富集与断裂带密切相关。该区泥岩裂缝油气藏的形成主要与断层作用、异常高压流体及盐岩塑性流动引起局部构造变形有关,盐层的上下封闭使之形成“自生自储”的泥岩裂缝油气藏。The fractured mudstone reservoir with salt interbed is a special reservoir type. The extensively developed salt - mud interbed existed in ES4 and Es3 of Wenliu region in Dongpu Depression, and ES32 was the abundant zone of the fractured mudstone reservoir with salt interbed. The reservoirs in these oil reservoirs in Wenliu region were source rocks, and the oil -gas enrichment was closely related to fault belts. The formation of the fractured mudstone reservoirs in this area was related to the local tectonic deformation caused by faulting, abnormally high fluid pressure and plastic flow of salt rock. And the sealing up and down of salt beds formed fractured mudstone reservoirs with autogeny and autostorage.
