复杂小断块油气藏滚动勘探开发研究

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入机制入手，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 rolling E&P of reservoirs in small complicated faulted-blocks

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.
