巖溶平原
英文
karst plain-
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

摘要文章敘述了硯平高速公路巖溶勘察情況,分析了硯平高速公路巖溶的工程地質特徵及工程地質問題,提出了硯平高速公路巖溶的工程地質分類及處治原則,對巖溶地區公路的建設具有一定的參考和指導作用。The pattern of diagenetic and porosity evolution are established. the primary porosity of the reservoir rocks was 35 %, which was reduced by 21. 7 % by compaction and pressure solution and 8. 2 % by cementation. the secondary pores were produced by organic acids " dissolution during organic matter maturing stage, resulting an increase of porosity by 5 %
預測本區砂巖原始孔隙度為35 ,經機械壓實和化學壓溶作用孔隙度損失了21 . 7 ,后經自生礦物的膠結作用,孔隙度損失了8 . 2 ,當進入有機質成熟階段,有機酸的溶解作用產生次生孔隙,使孔隙度增加5 ,現今保存的平均孔隙度為10 . 1 。Since the generated gas from gas source rocks is expelled in the form of separate phase, can it be useful for the form of pool. so, the expelling gas value of carbonate gas source rocks is more important, this paper, based on the principle of material balance, divide the tough problem of expelling hydrocarbon into relatively and easily investigated problems of gas hydrocarbon generation, residual and diffusion gas hydrocarbon and evaluate gas source rocks in temis of the magnitude of expelling gas ; hydrocarbon ( quantity of expelling gas = gas quantity of generation - adsorption - dissolving in oil - dissolving in water - diffusion )
由於所生成的氣態烴只有從源巖中以游離相運移出來之後才能對氣藏的形成做出貢獻,因此對氣源巖的排氣能力的評價顯得猶為關鍵。本文根據物質平衡法原理將比較棘手的排氣態烴問題,分解成相對較易考察的生氣態烴問題和殘留、耗散氣態烴的問題,以排氣量大小(排氣量=生氣量?吸附氣量?油溶氣量?水溶氣量?擴散氣量)為評價碳酸鹽巖氣源巖標準。For the first time, take tarim basin as an example to establish theoretical, industrial threshold value of organic enrichment of carbonate source rocks. calculate gas quantity of generation, adsorption, dissolving in oil, dissolving in water, diffusion of unit area carbonate rocks at different geologic conditions. and then according to the material balance principle, figure out the corresponding organic carbon content when gas being started expelling from source rocks with separate phase
分別計算了不同地質條件下單位面積碳酸鹽巖的生氣量及源巖和圍巖各種形式的殘留和耗散氣量(吸附氣量、油溶氣量、水溶氣量、擴散氣量) ,進而根據物質平衡原理計算出源巖開始以游離相有效排氣時所對應的有機碳含量,並將它作為該地質條件下氣源巖的有機質豐度理論下限值。Calculate gas quantity of generation, adsorption, dissolving in oil, dissolving in water, diffusion of unit area carbonate rocks at different geologic conditions. and then according to the material balance principle, figure out the corresponding organic carbon content when gas being started expelling from source rocks with separate phase. regard it as the theoretical threshold value ( tocmin ) of gas source rocks at that same geologic condition
