关于井炮激发参数优化设计的思考

On optimization of explosion parameters

利用正演模拟的手段进行分析,对影响井炮激发的不同影响因素展开分析,结合对炸药特征阻抗与围岩的阻抗匹配系数、炸药几何耦合系数、激发药量、井深等方面进行分析,对井炮激发参数进行优化设计.通过优化设计,寻求有效提高地震子波品质的方法.结合实际的地震地质条件和地震勘探目标,设计最佳的井炮激发参数,提高地震勘探的效益.

In the article the parameters related to explosion in seismic survey are analyzed through forward modeling. Through the optimization of parameters, such as the type of the dynamite and its quantity and impedance coupling ratio and the geometrical coupling ratio and so on, the method to improve wavelets quality could be obtained, by taking the objects in survey and the local geological characteristic into account.
