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
研究認為該氣藏構造簡單，只在鳳凰山形成了一個小型的鼻狀構造；屬於三角洲前緣亞相沉積模式，水下分流河道和河口壩是有利的沉積微相；儲層物性差，儲層巖石的孔隙類型主要有粒間孔、粒間（內）溶孔及少量晶間微孔；影響蓬萊鎮組氣藏儲層孔隙結構及儲集性的因素有巖相、巖性條件及成巖作用；所有測試井自然產能都極低，必須經加砂壓裂后才有工業開采價值，且投產初期，油套壓下降較快，氣井產量下降迅速。The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes, which, in turn, have exerted a direct and important effect on the sequence stratigraphic development. collectively, the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones. the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage, and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage
系統的儲層特徵研究表明，該區延長組儲層成因類型主要為三角洲前緣水下分流河道、河口砂壩及三角洲平原水上分流河道微相細粒長石砂巖、粉砂巖；儲層巖石經歷了壓實，膠結，溶蝕等成巖作用，歷經早成巖機械壓實和化學壓溶孔隙縮小期、晚成巖a亞期溶蝕作用孔隙擴大期及晚成巖a亞期（ b亞期）膠結充填孔隙縮小期三個成巖-孔隙演化階段；儲層物性總體上具有較低孔滲、低孔滲的特點，孔隙類型主要為粒間溶孔、殘余粒間孔隙、粒內溶孔、晶間孔及晶間溶孔，裂縫不發育，儲集巖排驅壓力和中值壓力較高，孔隙結構類型以細小孔-微孔隙，微細喉-微喉型為主。Major reservoir included sand bodies of subaquatic distributary channels in deltas, braided deltas, fan deltas, and sand bodies of turbidtte in deep lake
主要的儲集層有：三角洲、辮狀河三角洲、扇三角洲前緣水下分流河道砂體和深湖濁積巖砂體。Important gas - bearing reservoirs included sand bodies of distributary channels and subaquatic distributary channels in deltas and braided deltas, dolomitite in carbonate platform, and sand bodies in tidal flat and barrier island
重要的儲集層有：三角洲和辮狀河三角洲分流河道和水下分流河道砂體、碳酸鹽巖臺地的白雲巖以及潮坪、障壁島砂體。According to synthesize evaluate, the distributary channel sandbodies and river mouth bars are best reservoir
通過綜合評價認為，水下分流河道和河口砂壩微相為本區最好的儲集層。Considering all factors in trap - forming, the most prospective reservoirs are the sub - water channel sandstones, the front sheet sandstones of braided delta and bedded turbidity sandstones. the petroleum exploration targets are identified further
綜合成藏要素進一步研究，認為水下分支河道、辮狀三角洲前緣席狀砂和小型層狀濁積砂體是比較有利的儲集體。分享友人
