Abstract

The northern part of the oilfield has entered the development stage of ultra-high water cut period. With the increase of well pattern density, the mining objects gradually become worse, which puts forward higher requirements for development adjustment and fine potential tapping. The research block is cut into relatively independent parts by extended faults, resulting in irregular well pattern distribution and imperfect injection production, which has a great impact on the development effect. It is difficult to clearly understand small faults, micro amplitude structures and fracture zones by relying solely on logging data. At present, the development of seismic data is widely used in the old area of Changyuan. Therefore, we must use three-dimensional seismic technology to re understand faults, improve the injection and production system in fault areas, further excavate remaining oil and improve the development effect of fault areas. The existing data have conducted a detailed study on the fault, and the three-dimensional structural geological modeling has found that the overall structural shape has little change, but relatively small faults have been found and re recognized. In this paper, through the new interpretation of infill wells, it is difficult to combine, and there may be small faults between wells.
