  1. 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。
  2. According to the abundance well logging, mud logging and core analysis data, gaotaizi reservoir has been classified into four sand group with the principle of cycle comparison and classified control. based on the detailed study of lithologic character, sedimentary structure, paleontologic fossils, depositional sequence, rock association and logging data, the microfacies of the studied area are divided into such seven types : subaqueous distributary channel microfacies ; river mouth bar microfacies ; subaqueous interdistributary channel microfacies ; subaqueous crevasse channel microfacies ; subaqueous natural barrier microfacies ; distal bar microfacies ; delta front sheet sand microfacies. the characteristic of each sedimentary microfacies are described detailedly

    通過研究大量測井、錄井資料和巖芯資料，依據「旋迴對比，分級控制」的原則，把研究區高臺子油層劃分為g 、 g 、 g 、 g四個砂層組。通過對研究區巖性、沉積構造、古生物、沉積序列、巖石組合及測井曲線特徵進行研究的基礎上，認為研究區高臺子油層屬於三角洲前緣亞相沉積，並將研究區沉積微相劃分為：水下分流河道、河口壩、水下分流河道間、水下決口扇、水下天然堤、遠砂壩、席狀砂等七種微相類型。
  3. According to the deposit mained lithologic trap, lithologic - structure complex trap, the sedimentary system research is the base of reservoir assessment and prognosis. the gas concentration of shanxi group and xiashihezi group of permain system in tabamiao area was mainly constrolled by sedimentary facies belt. therefore, it is an important content in this geological research area that study sedimentary systems character of object layers, research combined character of subfacies and microfacies, and its regular between vertical evolution and reservoir sand bodies

    對于以巖性圈閉、巖性?構造復合圈閉為主的氣藏，開展沉積體系的研究是進行儲層評價和預測的基礎，和鄂爾多斯岔地其它地區一樣，塔巴廟區塊二疊系山西組和下石盒子組氣層的富集主要受沉積相帶的控制，因此，區內目的層段的沉積體系特徵、亞微相組合特徵、垂向演化規律和有利儲集砂體分佈規律的研究就成為該區地質研究的一項重要內容。
  4. China is a petrobleum - production country mainly possess terrestrial petroliferous basin, in the depocenter of the terrestrial petroliferous basin, the sandstone lithologic oil pools that the primary reservoirs are variouskinds of turbibite sand bodies and have large amount of reserves distribute widely, and this is a chief character of the terrestrial petroliferous basin. for the special concealment of the turbidite sand bodies, it is very difficult to predict and describe the tubidite reservoirs

    中國是一個以陸相含油氣盆地為主的產油國，在陸相湖盆的沉積中心地區，廣泛存在著以各類濁積砂體為主要儲集體且儲量相當豐富的砂巖巖性油藏，構成陸相含油氣盆地的一大特色。由於濁積砂巖體的特殊隱蔽性，給濁積巖儲層預測和描述帶來了很大困難。
  5. China is petroleum production country where the oil is mainly produced in continental hydrocarborn - bearing basin. it is special feature of contineutal oil - gas - bearing basin that sandstone lithologic reservoir with variety lithologic sandbody and vely enriching rolk oil hides extensively exsited. in the center region of continental lake basin sedmentary region, rf s very difficult to predict and descript turbidite reservoir because of the special subtle of turbidite sandbody. therefore studing the sediments character of turbidite reservoir and the description methord of turbidite reservoir has the important and realistic meaning for the explore and development of turbidite reservoir

    中國是一個以陸相含油氣盆地為主的產油國，在陸相湖盆的沉積中心地區，廣泛存在著以各類濁積砂體為主要儲集體且儲量相當豐富的砂巖巖性油藏，構成陸相含油氣盆地的一大特色。由於濁積砂巖體的特殊隱蔽性，給濁積巖儲層預測和描述帶來了很大困難。因此，研究濁積巖儲層的沉積特徵和濁積巖油藏的描述方法對于濁積巖油藏的勘探開發具有重要的現實意義。
