【摘要】 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800m井距上尝试的井间地震技术。更多还原

【Abstract】 Thelargewellintervalcross-wellseismictechniquewas carried out in Shu 68 area ofLiaohe Oilfield. The spatial location of sand-shale alternating beds, the connection of main reservoir and the distribution of fluids were achieved by P-wave and S-wave tomography and reflection migration imaging from cross-well data. The commercial oil flows were got fromthree wells based on integrated geological studyofcross-well seismic technique. This was the first time that the well intervalofcross-wellseismictechniquewaslager than 800 m, which improved thecross-welltechniqueapplication verymuch.更多还原
