The invention provides a well spacing optimization method for compact conglomerate, and belongs to the technical field of oil and gas field development. According to the method, a trilinear flow unstable seepage model in Kappa software is utilized, and the single well recoverable reserves EUR and the recovery efficiency EOR are predicted according to geological and engineering parameters of a well group in a prediction time period; calculating a net present value of unit reserves of the horizontal well according to the recoverable reserves of the single well and the investment; and selecting the corresponding well spacing when the net present value of unit reserves is positive and the recovery ratio is maximum as the optimal well spacing. According to the compact conglomerate well spacing optimization method, the benefit development risk of the compact conglomerate oil reservoir horizontal well can be greatly reduced, and the development benefit is improved. 本发明提供了一种致密砾岩的井距优化方法，属于油气田开发技术领域。本发明利用Kappa软件中三线性流不稳
