摘要針對高煤級煤儲層滲透率尤其是其動態變化規律極少開展研究的現狀,基於現代測試技術和沁水盆地排采效果較好的煤層氣井實測排采數據,利用目前國際上較為先進的煤層氣數值模擬軟體comet2 ,採用分段擬合的方法對煤層氣井的產氣、產水過程進行歷史擬合和修正,進而對高煤級煤儲層滲透率在開采中的動態變化規律進行了探討。The higher - permeability region for cbm exploration are panzhuang - yangcheng, yangquan - shouyang and taiyuan xishan coalfield in qinshui basin
預測結果顯示,沁水盆地有利於煤層氣開發的高滲區,主要集中在南部的潘莊陽城、北部的陽泉壽陽及太原西山煤田等地區。More than forty coal samples collected from thirteen coal mines in the north, central and south parts of qinshui basin were studied in detail so as to find out the main control factor affecting pore differential development of the high - rank coal reservoirs in the basin
為查明影響沁水盆地高煤級煤儲層孔隙系統差異發育的主控因素,對采自該盆地北、中及南部6個市縣13個礦區的40餘件樣品進行了詳細解剖研究。The basement of the basin is consist of precambrian crystal basement and paleozoic folding basement, while the cover has undergone the evolution of intra - continental rife in permian, down warped basin in triassic - cretaceous period and inter - mountains basin in tertiary. the main sediments are huge - thick volcanic rock, shallow intrusive rock and tuff in early permian, dark mudstone, marl and muddy dolostone in lucaogou formation in middle permian, huge thick volcanic rock, intruder in tiaohu formation in middle permian, miscellaneous sandy gravel, sandstone and gray mudstone in triassic ( the red is under the gray, and huge - thick dark gray, gray sandy gravel, sandstone, mudstone with coal layer in jurassic
盆地基底由前寒武紀結晶基底和古生代褶皺基底組成,盆地蓋層則經歷了二疊紀的裂谷盆地、三疊紀?白堊紀的坳陷盆地和第三紀后的山間盆地的演化過程。盆地主要沉積了下二疊統巨厚火山巖、淺成侵入巖和凝灰巖;中二疊統蘆草溝組的暗色泥巖、泥灰巖、白雲質巖石以及條湖組的巨厚層火山巖、侵入巖;三疊系雜色砂礫巖、砂巖及灰色泥巖(下紅上灰) ;以及侏羅紀厚層深灰、灰色砂礫巖、砂巖、泥巖夾煤層。The palaeogeographic research indicate that the palaeogeographic outline of the study area recorded the evolution from a sedimentary basin in which the shallow - water carbonate platform sediments and deep - water terrigenous clastic submarine fan developed from southeast to northwest and northeast during the late triassic through a submarine sheet - like model composed of deep - water sandy turbidite and fine - grained turbidite during the early jurassic to a terrigenous clastic barrier coast during the middle and late jurassic and finally to the coal - bearing delta sediments during the late cretaceous
古地理分析表明,研究區晚三疊世古地理輪廓是一個從東南向西北和東北方向由淺水碳酸鹽臺地及深水陸層海底扇沉積共同發育的沉積盆地;早中侏羅世,演變成為一個由深水砂質濁積巖和細屑濁積巖組成的水下席狀體沉積;進入中晚侏羅世,其古地理表現為一個陸屑淺海有障壁海岸;到了晚白堊世,研究區表現為以含煤沉積為特徵的三角洲相沉積。The characteristics of gas from fluid inclusion show that these gas are generated from coal and is very different from gas in gas fields. authors speculate the times of gas filling reservoir are two at least. at early time, it is probably coal type gas
用這種方法對鄂爾多斯盆地中部氣田的儲層包裹體中烴類氣體碳同位素進行了測定,結合單個包裹體成分及均一溫度認為該區有兩期成藏史,並且早期可能主要來源於煤成氣。The results are shown as the followings : on the basis of studies of depositional environment of source rock and its petroleum potential assessment, the biomarker compositions of the five source beds ( hq, j2k, jiy, tjt, tsh ) in kuche basin are analyzed in detail and the effects of depositional environment and maturity on the biomarker compositions are also discussed. the results show that there is not clear correlation between the distribution of biomarker composition and the ages of triassic and jurassic. it is proposed for the first time in the kuche basin that the changes of biomarker composition in the coal can be classified into three stages with the maturity, and the regular changes of different biomarker parameters in the coal are revealed
以烴源巖沉積環境為背景,詳細剖析了庫車前陸盆地五套烴源層( j _ 2q 、 j _ 2k 、 j _ 1y 、 t _ 3t 、 t _ 3h )中煤、炭質泥巖、湖相泥巖、煤系泥巖的生物標志物組成特徵,分析了沉積環境、成熟度對生物標志物組成的影響,指出同一烴源層在盆地不同地區生物標志物組成的差異,並認為生物標志物組成特徵與三疊系和侏羅系的時代對應關系不明顯。On the basis of comprehensive analyses on hydrocarbon accumulation conditions in the four representative foreland basins, kuqa basin, southern junggar basin, western sichuan basin and northern margin of qaidam basin, some conclusions are made as follows ; the foreland basins in central and western regions of china are characterized by multi - set source rocks dominated by coal measure ; heterogeneous reservoirs ; multiple and sealing cap nick ; anticline traps ; unblocked transport system composed of fault, unconformity and highly permeable sand body ; anti poor conservative conditions. etc
在綜合分析和對比庫車、準南、柴北緣和川西等具有代表性的前陸盆地的油氣成藏條件的基礎上指出,中西部前陸盆地具有以煤系為主的多套源巖,發育非均質儲集層,多套多封閉性的蓋層,以背料為主要圈閉;斷裂、不整合和高滲透砂體組成良好輸導體系,保存條件較差等特點。分享友人
