【摘要】 十屋油田左旋走滑构造运动开始于沙河子—营城组沉积末期,至登娄库组沉积末期时最为强烈,形成了小宽走滑带等3个NE向挤压走滑带。三维地震研究表明,十屋油田走滑构造样式并非单纯走滑,而是呈前期走滑后期伸展或前期走滑后期挤压的发育状态,出现了负花状、"F"型、反"Y"字型和正花状等构造样式。左旋走滑运动产生的构造样式不仅控制着十屋油田沉积沉降中心的发育,而且对油气的运聚也有着重要意义。更多还原

【Abstract】 The tectonic movement of left-lateral slip in Shiwu Oilfield began from the depositional stage of Shahezi Formation to the last depositional stage of Yingcheng Formation.It became the most intense in the last depositional stage of Denglonku Formation and formed three press-slip zones to the northeast including Xiaokuan strike-slip zone.Three-dimensional seismic study shows that the strike-slip tectonic style in Shiwu Oilfield is not simply a slip,but slip in the beginning and extension in the end or slip in the beginning and pressing development in the end,and there are some kinds of tectonic styles,such as negative flower,"F" type,anti-"Y" type and positive flower.The tectonic styles produced by the movement of left-lateral slip not only control the development of the deposition and sedimentation centre,but also are meaningful to the petroleum migration and accumulation.更多还原
