摘　　要：YA是江苏油田最为典型的复杂小断块油气藏。断块破碎、玄武岩多次波干扰、辉绿岩屏蔽是地震勘探面临的主要困难。为此,在该地区采取了针对性的措施:①资料采集采用了合适的观测系统,如优化测网方向、提高覆盖次数;②采用处理解释一体化方法并借助于一些针对性的处理技术,以提高资料的处理质量;③运用综合的、多阶段的解释研究方法,即从研究火成岩的侵人机制入手,用地质理论指导地震解释,辅以三维立体解释技术,实现精细构造解释。上述措施的实施,使该区的滚动勘探开发取得了很好的成果,探明地质储量显著增加。The geologic structure of YA area is very complex because of broken fault blocks, the multiple interference caused by basalt and shielding action of diabase, which is a typical small complex hydrocarbon reservoir in Jiangsu oilfield. In order to make a breakthrough, to start with seismic data acquisition, using an proper layout, such as optimization survey grid direction, increasing coverage; on the basis of integrated study for processing and interpretation, improve the quality of data process by means of some effective process technologies; The fine structure interpretation is realized by means of comprehensive, multiple periodic interpretation and research, beginning with researching the mechanism of igneous rock invasion, geology theories as a guide, and 3D interpretation technology as an assistance; Finally, a good result has been achieved in the rolling E&P of the area.
