苏北盆地火成岩发育区地震资料品质一直以来不能满足勘探的需要。近年来江苏油田加强了在火成岩发育区的方法设计、野外试验以及处理技术研究。在观测系统设计上，通过对火成岩发育范围的识别，根据模型正演及采集参数分析，针对火成岩的分布范围合理设计采集方案。在野外采集中，通过详细的近地表结构调查、采集试验及严格施工，确保采集质量。在高精度三维实施区块中，火成岩发育区的地震资料品质有较大提高。

Up to now,quality of seismic data cannot meet requirements of exploration in igneous rock area in Subei Basin.In recent years,method design,field test,and processing technology have been strengthened with implementation of high-precision 3D exploration in Jiangsu Oilfield.On the observation system design,a reasonable acquisition scheme based on distribution features of igneous rocks was designed according to identification of igneous rock growth range,for-ward modeling,and analysis of acquisition parameters.In field acquisition,quality of raw seismic data can be guaranteed by detailed near-surface structure investigation,acquisition test,and strict construction.The seismic data quality of igneous rocks has been improved remarkably in high-precision 3D exploration blocks.
