大庆长垣油田主城区高精度三维地震激发技术
|
摘要
大庆长垣主力油田已经进入超高含水开发后期,大庆油田的主城区成为剩余油开发的主战场。本文针对主城区地面建筑及采油设施密布、人口密集、干扰源分布广、表层结构复杂、地质任务要求高、生产安全难度大等一系列难题,重点进行了地震激发技术研究及其参数试验,对井炮激发、激发安全距离、城区激发药量选择、激发点特观设计、地震激发标准化操作等进行研究,形成了主城区三维地震激发配套技术,而且获得了显著地质效果。
The major oil-fields in Daqing placanticline already came into late super high water-bearing development period.The urban area in Daqing Oil-field are now the major target for development of the residual oil.Regarding a series of difficulties in the major urban area,such as dense production facilities,dense population,wide distribution of interference source,complicated surface structures,hard geological targets and difficult safety environment and so on,the key technique in seismic shooting was designed in seismic acquisition,the studies on borehole shooting,shooting safety distance,selection of shooting charge in the urban area,the special design for the shooting points and the seismic shooting standardized operation were conducted,the relevant techniques which were involved in the 3D seismic shooting were formed,the remarkable geological effects were acquired.
