Abstract:
As there are many normal fauhs in Biyang depres sion,the research on strike-slip fauhs is seldom carried out.With the advancement of exploration and develop ment,more and more local structures have been figured out.However,some of these structures can not be ex- plained in the view of normal faults.Taking Xinzhuang oilfield as an example,the article demonstrates the exist- ence of strike-slip fauhs in Biyang depression and discus- ses its formation mechanism for the first time,which is based on the incoordination of structure,dragging-pul- ling phenomenon on both sides of the incoordination belt, time slice,drilling core,etc.
