【摘要】：簡單斜坡是具有構(gòu)造平緩和低斷裂密度特征的弱構(gòu)造帶,斷層位移褶皺作為簡單斜坡內(nèi)一種常見的斷層相關(guān)褶皺類型,能夠形成重要的油氣圈閉構(gòu)造.為了準(zhǔn)確識別斷層位移褶皺及其相關(guān)油氣圈閉,以三維地震為基礎(chǔ),結(jié)合不同生長階段斷層位移變化來闡明不同類型斷層位移褶皺形成機(jī)制,應(yīng)用斷層分段性和斷層平面分段生長階段定量表征方法來識別斷層位移褶皺的類型及發(fā)育部位.同時,以文安斜坡中南部為研究靶區(qū),探討位于文安油田內(nèi)史各莊和議論堡地區(qū)主要含油區(qū)附近斷層形成的斷層位移褶皺類型,闡明其相關(guān)圈閉構(gòu)造與油氣分布關(guān)系.研究結(jié)果表明,王仙莊斷層和SGZ1斷層都處于"硬連接"生長階段,能夠形成"硬連接"斷層位移褶皺,SGZ2和SGZ3斷層處于相互作用的"軟連接"階段,形成"軟連接"斷層位移褶皺.斷層位移褶皺相關(guān)圈閉發(fā)育部位與文安油田油氣分布關(guān)系表明斷層位移褶皺相關(guān)圈閉構(gòu)造是文安油田主要的含油氣圈閉類型,富集了文安油田大部分的油氣儲量.
[Abstract]:Simple slope is a weak structural zone with the characteristics of gentle structure and low fracture density. Fault displacement fold is a common type of fault-related fold in simple slope. In order to accurately identify the fault displacement fold and its related oil and gas traps, it is based on 3D earthquakes. The formation mechanism of different types of fault displacement folds is explained by combining the variation of fault displacement in different growth stages. The types and development sites of fault displacement folds are identified by means of quantitative characterization of fault segmenting and fault plane growth stages. At the same time, the central and southern part of Wenan Slope is taken as the research target. This paper discusses the types of fault displacement folds formed by faults near the main oil-bearing areas in Gezhuang and Yiliubu areas of Wenan Oilfield, and clarifies the relationship between the relevant trap structures and the distribution of oil and gas. Both the Wangxianzhuang fault and the SGZ1 fault are in the "hard connection" growth stage, which can form the "hard connection" fault displacement fold, SGZ2 and SGZ3 faults are in the "soft connection" stage of interaction. The formation of "soft connection" fault displacement fold. The relationship between the development of fault displacement fold associated trap and the distribution of oil and gas in Wenan Oilfield indicates that the fault displacement fold related trap structure is the main type of oil-bearing trap in Wenan Oilfield. It has enriched most of the oil and gas reserves in Wenan Oilfield.
