在辽河曙68 井区开展的大井距井间地震试验中，通过井间纵、横波层析成像和反射波偏移成像，得到井间砂泥岩互层展布，解释出两井之间主力储层的连通情况和流体分布情况。在地质综合研究基础上，在辽河曙光油田部署了3 口开发井，均获得工业油流。本次试验，是首次在大于800 m 井距上尝试的井间地震技术。

The large well interval cross-well seismic techniquewas carried out in Shu 68 area ofLiaohe Oilfield. The spatial location of sand-shale alternating beds, the connection ofmain reservoir and the distribution of fluids were achieved by P-wave and S-wave tomography and reflection migration imaging fromcross-well data. The commercial oil flows were got from three wells based on integrated geological study of cross-well seismic technique. This was the first time that the well interval ofcross-well seismic technique was lager than 800m,which improved the cross-well technique application very much.
