In 1979 in terms of the resources of the cement oil field dr t. j. donovan, worked in the geo - survey graduate school, proposed that there is diagenetic magnetite in sediment terrane above oil and gas reservoir
1979年美國地調所t . j . donovan博士根據cement油田資料推測在油氣藏上覆沉積巖層中存在與烴類垂向運移相關的成巖作用磁鐵礦。 -
From the dongying formation ( ed ) to neogene, the shahejie formation was located in the late diagenetic stage a1 ~ a2 ; the oil and gas pools formed in a wide scale. at present the lower e2s3, with overmatured source rocks and low porosity reservoir rocks, gets into the late diagenetic stage b - c in the northern qibei sag where is not favorable for petroleum accumulation, but the others of the shahejie formation are locate still in the late diagenetic stage a1 - a2 and propitious to form oil and gas pools based on the diagenetic numerical modeling under the condition of overpressure, we build a multiple unit cubic equation model for porosity prediction, as the result of the application of qibei sag, the prediction error is less than 2 %, and the precision excess that of foreign same model
歧北凹陷的模擬結果表明，在沙河街組沉積末沙河街組三段就進入晚成巖階段a _ 1期，油氣藏開始形成；在東營組沉積時期晚第三紀，沙河街組大部分地層處于晚成巖階段a _ 1 a _ 2期，生、儲、蓋層發育，是其主要成藏期；現今在歧北凹陷北部沙三段下部進入晚成巖階段b c期，儲層物性較差、不利於成藏，其他層段仍處于晚成巖階段a _ 1 a _ 2期，有利於油氣藏的形成。 -
In order to evaluate resource objectively, it is very important to find out the origin and the main source of co2 and to study the distribution pattern of hydrocarbon, nonhydrocarbon gas and probe the controlling factors, diagenetic evolution of different reservoirs ( rich in co2 or rich in cflo and the relation between diagenetic features and co2 have been studied systematically by using conventional and advanced techniques and the integrated the methods of petrology and geochemistry. based on the petrologic and geochemical data as well as dynamics reactions of carbonate ? lay minerals, the origin and distribution of co2 have been synthetically discussed
論文中應用常規及先進的測試技術，採用巖石學與地球化學相結合的方法，重點研究本區淺層氣藏富co _ 2儲層與富ch _ 4儲層的成巖演化特徵及其與co _ 2的相互關系，並通過天然氣的地球化學研究以及碳酸鹽礦物與粘土礦物反應形成co _ 2的熱力學分析，對co _ 2來源及分佈進行了初步分析和探討。 -
On the base of the sedimentary facies, diagenesis, diagenetic facies and petrophysical property, we prospect six advantageous regions, such an analysis shows clearly the trend of oil and gas exploration and development in the future and has been proved by the results of testing in the wells drilled within the region
以有利沉積相、成巖作用和成巖相為基礎，以物性參數和h 、 k 、 s _ 0綜合系數值為線索進行了儲層遠景預測，這對該區油氣勘探具有重要意義。
