摘要

这里叙述了在大港油田进行的羊11~12井和羊11~13井及港9~72~1井和港8~71~1井井间声波层析试生产的成果,层析图上含油砂体在二口井边棱的深度与以往地质和测井解释的油层深度相吻合,层析解释深度和测井解释的油层深度最大差异为0.8 m~1.6 m,并圈定了含油砂体的分布形态。表明了井间声波层析成像技术对查明油层横向分布,确定油层尖灭位置和圈定含油砂体的分布形态是有效的,同时也显示出井间声波层析成像作为一种油田开发、监测技术更具有潜力和应用前景。
The test results of cross-borehole acoustic tomographic surveys for two pairs of boreholes, Boreholes Yang 11-12 ～ Yang 11-13 and Boreholes Gang 9-72-1 ～ Gang 8-71-1 in the Dagang Oil Field have been presented in the paper. The depths of oil-bearing bodies shown in the tomograms roughly coincides with those interpreted from geological and well-logging data, with deviation of only 0.8 ～ 1.6 m. The appearances of oil-bearing bodies could be mapped with the tomography, indicating that the tomographic technology is effective for mapping lateral distribution and thinning out of oil-bearing layers and therefore useful for the development and monitoring of oil fields.
