【摘要】 在车排子地区春光油田,运用地震砂体解释方法,从井出发,井震结合,通过合成记录标定层位,以合成记录和地震正演模拟为指导依据,有砂体的地方进行解释,没有砂体的地方不解释,在全工区等时地层格架内进行砂体识别。通过砂体平面分布图刻画砂体边界、分析沉积体系,并结合该区成藏条件,寻找有利勘探目标。共找出有利圈闭8个,其中已知油藏4个,预测圈闭4个。更多还原

【Abstract】 The present petroleum exploration status has trended from structural reservoirs to lithologic and stratigraphic reservoirs. The paper takes Chunguang oilfield of Chepaizi area as an example, briefly introduces the principles and the methods of seismic sands interpretation. Starting from the well, making calibration horizon by synthetic seismic and forward modeling, sand bodies’ recognition has been carried out in the stratigraphic framework. Sedimentary systems and sands boundary are graven by the plane distribution of sands bodies. In the end, there are total 8 effective traps have been identified.更多还原
