【摘要】：準噶爾盆地北緣哈拉阿拉特山構(gòu)造帶經(jīng)歷多期構(gòu)造運動的疊加改造,地質(zhì)結(jié)構(gòu)復雜,油氣運聚規(guī)律復雜,極大地制約了油氣勘探。以已發(fā)現(xiàn)油氣藏為研究對象,采取地質(zhì)解剖與地球化學分析相結(jié)合的方法,根據(jù)原油中生物標志化合物和含氮化合物等示蹤指標在運移過程中的地質(zhì)色層效應(yīng)原理,對不同構(gòu)造單元的油氣輸導特征進行研究。結(jié)果表明,超剝帶與推覆—沖斷帶屬于不同的油氣輸導系統(tǒng),兩者之間存在侏羅系八道灣組底不整合風化黏土層、不整合面之上灰(泥)質(zhì)礫巖和推覆體頂部石炭系火山巖風化"硬殼"多重致密分隔層;且兩者具有不同的油氣來源和油氣輸導樣式。淺層超剝帶原油來源于瑪湖凹陷風城組烴源巖,為遠源"斷—毯"橫向輸導模式;中深層推覆—沖斷帶油氣來源于哈山地區(qū)風城組烴源巖,為近源"多斷"聯(lián)合垂向輸導模式,其中,推覆疊置區(qū)為"斷—縫"網(wǎng)狀輸導,沖斷疊加區(qū)為"斷—砂"階梯輸導,斷褶變形區(qū)為斷層優(yōu)勢輸導。不同構(gòu)造單元的輸導要素差異配置控制了油氣運聚成藏,形成了研究區(qū)立體含油的分布格局。
[Abstract]:The tectonic belt of the north margin of the Zhilerian basin is subjected to the superposition and transformation of the multi-period tectonic movement, the geological structure is complicated, the oil and gas migration and accumulation law is complicated, and the oil and gas exploration is greatly restricted. taking the discovered oil and gas reservoir as the research object, taking the method of combining the geological and geochemical analysis, and according to the principle of the geological color layer effect in the migration process of the trace indexes such as the biological marker compound and the nitrogen-containing compound in the crude oil, The characteristics of oil and gas transmission in different tectonic units were studied. The results show that the overstripping zone and the nappe thrust belt belong to different oil and gas transmission systems, and there is a multiple dense separation layer of the weathered "hard shell" of the carboniferous volcanic rock on the top of the upper Carboniferous volcanic rock in the upper part of the Jurassic Abay Formation. And the two have different oil and gas sources and oil and gas transmission patterns. The crude oil in the shallow layer is derived from the source rock of the Fengcheng Formation of the Mahu depression, and it is the lateral transport mode of the far-source "cut-off blanket". The oil and gas in the deep-layer thrust belt are derived from the source rock of the Fengcheng Formation in the area of Haisha and the vertical transport mode of the near-source "multi-break". The nappe overlap area is the "cut-off seam" mesh transmission, and the thrust and break overlap area is the "cut-off sand" step transmission, and the fault fold deformation area is the fault advantage transmission. The distribution pattern of three-dimensional oil-bearing distribution in the study area is formed by the differential configuration of the transmission factors of different tectonic units.
