DISCUSSION ON FORMING MECHANISM OF THE SHIQIANFENG FORMATION FLOWER GAS POOL IN EASTERN ORDORS BASIN
鄂尔多斯盆地东部石千峰组浅层气藏成藏机理探讨

The flower gas pool of the Shiqianfeng formation has become the new exploration area because of it's the less exploration cost.The charactics of the flower gas pool is the highter scaling factor of the lighter sergment,the lower puress of the pool and the coefficient of the pool pressure.At the same time,the flower gas pool was controlled by sandstone reservoir.the flower gas pool of Shiqianfeng formation is the Secondary gas pool.During the Yanshan movement,the formation in eastern Ordos basin was been lifted and eroded,the surpressure lay out the down formation such as the Shihezi formation and Shanxi formation was been released.when the surpressure being released,aboundance of microfissure was been made in the mud which was made the well regional cover,and became the mainly pathway of the gas from source rock to the Shiqianfeng sandstone reservoirs.
