The result is that this gas pool has simple structure , only forms a little nose - like structure at the district of fenghuangshan ; this pool belongs to delta front sub - facies sedimentary model , the underwater distributary channel and mouth bar is the better sedimentary microfacies ; the physical property of the reservoir is poor , the type of pore of the reservoir rock mostly are intergranular pore , intergranular solution hole and little are intercrystalline micropore ; the influential factors of pore structure and physical property are lithofacies , lithologic character and diagenesis ; the off - take potentia of all the testing well are deadly shortness , the wells have the worth of industrial recovery only under the condition of going through sand fracturing , and in the early of binging into production , the oil and sheath pressure drop rapidly , the production of the well drop rapidly
研究认为该气藏构造简单，只在凤凰山形成了一个小型的鼻状构造；属于三角洲前缘亚相沉积模式，水下分流河道和河口坝是有利的沉积微相；储层物性差，储层岩石的孔隙类型主要有粒间孔、粒间(内)溶孔及少量晶间微孔；影响蓬莱镇组气藏储层孔隙结构及储集性的因素有岩相、岩性条件及成岩作用；所有测试井自然产能都极低，必须经加砂压裂后才有工业开采价值，且投产初期，油套压下降较快，气井产量下降迅速。
