摘要

The oil-bearing area in complicated fault-block oilfield is usually small and irregular,and the size of reserves is directly controlled by faults.To develop this kind of oilfield properly,the recognition accuracy of fault occurrence and location must be enhanced,providing the basis for the deployment of development wells.Using the profiling,formula and intersection methods,this paper analyzed the determining accuracy of fault,and according to such methods,the fault locations in some complicated fault-block oilfields such as Xinzhuang in Henan oilfield are determined.Based on the research result,14 horizontal wells along the structural high location close to the fault 15-25 m and 15 high angle deviated wells were deployed.After the horizontal wells were put into production,the initial oil production of single well is 9.5 t/d,the oil-gas ratio is 0.52 and the cumulative oil production of single well is 4 900 t,achieving a good development result,which can provide technique support for the development of such reservoirs.
