【摘要】 SG复杂断裂带具有得天独厚的油气富集条件,但是SG断裂带断层发育、构造破碎、地震资料品质差、构造不易落实,制约该区勘探的进一步发现。在针对性处理提高地震资料品质基础上,通过对SG断裂构造特征的认识,以走滑断裂模式来指导地震资料的解释,以精细断层解释为突破口,应用全三维的解释方法,提高了复杂断裂带圈闭识别和描述精度,在实际应用中取得较好的效果。更多还原

【Abstract】 SG complex fault zone has rich oil and gas conditions. But due to the fault development,structural blocks and low quality of seismic data,Shigang fault zone restricts the degree of exploration. In view of the geologic features of complex fault zone,this paper worked on the problems of complex fault zone’s seismic data imaging and trap structural description with the integration of date processing and interpretation. To choose processing modules with target and to improve the imaging effect of complex fault zone,the authors adopted delicate fault interpretation technique during data processing and built up geologic module to control it. Because of the use of 3-D interpretation technique,the accuracy degree of trap identification and description of fault zone is improved.And it turns out good effect in application.更多还原
