Influence of left-lateral slip on structural form in Shiwu Oilfield and it’s petroleum geological significance
Online published: 2011-06-20
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.
