  4. 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。
  5. Chang - 2 oil - bearing beds of the yanchang formation experienced three diagenetic stages of early diagenesis, late diagenesis and epidiagenesis

    研究區長2油層組經歷了早期成巖階段、晚期成巖階段和表生成巖階段三個成巖階段。
  6. They are skeletal sand bodies in system of delta and places of most reservoir distribution. the diagenetic processes that govern reservoir properties include the extent of compaction, cementation and dissolution of grains. we recognize that at the early diagenesis phase, mechanical and chemical compaction is very strong, which reduced the original porosity

    河口砂壩多位於分流河道或次一級分流河道河口部位，向湖盆中心呈放射狀分佈，因而河口砂壩砂體多構成朵狀砂體，覆蓋面積大、連片好，砂體厚度大，是本區已知油藏主要分佈區。
  7. The study of diagenesis and its stages let us think that the pingdiquan formation belongs to period " a " of early diagenesis

    成巖作用及階段研究認為二疊系平地泉組屬早成巖「 a 」期。
  8. 4, by making use of micro pore and permeability apparatus and optopn multifunction microscope etc. advanced reservoir testing equipments, the ability to show heterogeneity from micro to macro has been improved largely. k - level / k is more than 1. 4 in south region reservoir, that is to say, the permeability in section is worse comparing to that of level direction, which is caused mainly by mud layers : different stone facies results in different micro feature, and in the south region, fluvial sandstone has cementation, compaction, corrosion and exchanging diagenesis, which occurred in b stage of early period

    4 、應用微孔滲儀和opton多功能顯微鏡等先進的儲層測試儀器設備，大大提高了從宏觀到微觀表徵儲層非均質的能力；南區儲層中k _ （水平） k _的比值一般大於1 . 4 ，即垂向上滲透率相對於水平滲透率差，這主要是砂巖中泥質紋層造成的；不同巖石相的微觀特徵不同，南區河道砂儲層主要有膠結、壓實、溶蝕和交代等成巖作用，成巖階段屬早成巖b期。
  9. Abstract : mainly reviewed distribution of organic nitrogen, early diagenesis ( such as counteract - eutrophication, nitrification / denitrification et al. ), the controlling factors of nitrogen cycling ; and the relationship between nitrogen and ecological system in sediments in recent years, which may contribute to research the nitrogen marine biogeochemical process
