【摘要】：隨著鄂爾多斯盆地靖邊氣田擴(kuò)邊勘探的深入,在靖西地區(qū)奧陶系中組合白云巖儲(chǔ)層中已發(fā)現(xiàn)多個(gè)含氣區(qū),但各含氣區(qū)天然氣的富集程度差異明顯,尤其以靖西中部最為明顯,有關(guān)這種富集差異的原因尚未開展深入研究。為此,借助鉆井巖心、測(cè)井及儲(chǔ)層物性等地質(zhì)資料,從天然氣充注能力、輸導(dǎo)通道連通性、儲(chǔ)層發(fā)育特征等方面對(duì)比分析了靖西中部地區(qū)蘇127、蘇203及桃15等3個(gè)區(qū)塊天然氣成藏特征的差異,從而探討了靖西中部地區(qū)天然氣富集差異原因,并對(duì)有利勘探方向進(jìn)行了預(yù)測(cè)。結(jié)果表明,靖西中部地區(qū)蘇127區(qū)塊—蘇203區(qū)塊—桃15區(qū)塊天然氣富集的差異主要由下列因素造成:供烴窗口處的天然氣充注能力決定了天然氣富集程度;中組合儲(chǔ)層輸導(dǎo)通道的連通性影響了天然氣聚集成藏的位置;儲(chǔ)層的物性控制了天然氣聚集成藏的規(guī)模。綜合分析認(rèn)為,蘇127區(qū)塊北部—蘇203區(qū)塊—桃15區(qū)塊南部的馬五5亞段—馬五6亞段為有利勘探區(qū);馬五7亞段—馬五10亞段勘探潛力相對(duì)較差。
[Abstract]:With the further exploration of Jingbian gas field in Ordos Basin, many gas-bearing areas have been found in the dolomite reservoir of Ordovician assemblage in Jingxi area, but the gas enrichment degree of each gas-bearing area is obviously different, especially in the central part of Jingxi. The reasons for this enrichment difference have not been further studied. Therefore, with the help of geological data such as drilling core, logging and reservoir physical properties, from natural gas filling capacity, transportation channel connectivity, The differences of natural gas accumulation characteristics in Su127, Su203 and Tao15 blocks in the central part of Jingxi are analyzed in terms of reservoir development characteristics, and the reasons for the difference in natural gas enrichment in the central area of Jingxi are discussed. The favorable exploration direction is forecasted. The results show that the difference of natural gas enrichment between Su127 block and Su203 block and peach 15 block in central Jingxi area is mainly caused by the following factors: the natural gas filling capacity at the hydrocarbon supply window determines the degree of natural gas enrichment; The connectivity of the transport channel of the middle assemblage reservoir affects the location of the accumulation of natural gas and the physical properties of the reservoir control the scale of the accumulation of natural gas. The comprehensive analysis shows that the northern part of Su127 block, Su203 block and the southern part of Tao 15 block are favorable exploration areas, and the exploration potential of Ma W7 submember and Ma Wu 10 submember is relatively poor.
