【摘要】：利用重處理的二維地震測線對南黃海盆地北凹進行了精細的構(gòu)造解釋,揭示了三種不同類型的正反轉(zhuǎn)構(gòu)造樣式,分別是中南部的逆沖型、東部的壓扭型和北部的褶皺型,主要受控于其所處的不同構(gòu)造位置。通過典型地震測線的平衡剖面分析,并結(jié)合區(qū)域構(gòu)造動力學背景分析,認為北凹至少發(fā)生了三幕構(gòu)造正反轉(zhuǎn),主要受控于不同地質(zhì)時期太平洋板塊對歐亞大陸俯沖速度和角度的改變。其中,三垛組沉積之后,太平洋板塊俯沖角度逐步由北西向轉(zhuǎn)為南西西向,并且俯沖速度明顯增大,使得北凹處于北東南西向擠壓環(huán)境中,廣泛發(fā)育正反轉(zhuǎn)構(gòu)造,這也是最強烈的一幕正反轉(zhuǎn),表現(xiàn)為強烈的逆斷層活動和地層剝蝕。過度的正反轉(zhuǎn)作用可能對北凹油氣藏的形成造成了不利的影響。
[Abstract]:The fine structural interpretation of the northern depression of the southern Huang Hai basin has been carried out by using the reprocessed two-dimensional seismic survey lines, and three different types of positive and reverse structural patterns have been revealed, namely, the thrust type in the central and southern part, the compression-torsional type in the east and the fold type in the northern part of the basin. Based on the analysis of the equilibrium profile of the typical seismic survey line and the analysis of the regional tectonic dynamic background, it is considered that at least the positive and negative turn of the three-act structure occurred in the northern depression. It is mainly controlled by the change of the velocity and angle of the Pacific plate to the Eurasian continent in different geological periods. After the deposition of the Triple formation, the subduction angle of the Pacific plate gradually changes from NW to NW, and the subduction velocity increases obviously. The north depression is in the NSE westward compression environment, and the positive and reverse structures are widely developed. This is also the strongest positive and negative turn. It is shown by strong thrust fault activity and strata denudation, and the excessive positive and negative effects may have an adverse effect on the formation of the North Depression oil and gas reservoir.
