In the process of exploration, exploitation, and transportation of offshore oil, it is easy to cause leakage accidents due to bad environment, aging facilities, and violent collision. The existence of a large number of offshore oil spills has seriously affected the marine ecological environment; the treatment of crude oil pollutants not only has a very long treatment cycle, but also its treatment cost is immeasurable. In order to clarify the cost allocation of marine crude oil pollutants, this study constructs the cost allocation model of offshore crude oil based on game theory. Based on the characteristics of crude oil diffusion and the tidal current field model of the leakage sea area, the influence area of crude oil diffusion is analyzed, and the crude oil leakage diffusion model is constructed. Based on the Shapley value method, this paper constructs the cost allocation model of the tripartite game subject, and analyzes its stability and fairness. The results show that the fair index of Shapley method is 0.507, and the split index of the three subjects is 0.688, 0785, and 0.011.This model can ensure the fairness of cost allocation on the premise of ensuring the stability of the cooperative alliance. The crude oil diffusion model and cost allocation model constructed in this study will have certain guiding significance for compensation allocation in crude oil leakage.

在海上石油的勘探，开发和运输过程中，由于环境恶劣，设施老化，剧烈碰撞等原因，很容易造成泄漏事故。大量海上溢油的存在严重影响了海洋生态环境。原油污染物的处理不仅具有很长的处理周期，而且其处理成本是不可估量的。为了弄清海洋原油污染物的成本分配，本研究建立了基于博弈论的海上原油成本分配模型。根据原油扩散的特点和泄漏海域的潮流场模型，分析了原油扩散的影响区域，建立了原油泄漏扩散模型。根据Shapley值法，本文构建了三方博弈主体的成本分配模型，并对其稳定性和公平性进行了分析。结果表明，Shapley方法的公平指数为0.507，三个主体的分裂指数分别为0.688、0785和0.011，该模型可以在确保合作联盟稳定的前提下确保成本分配的公平性。本研究构建的原油扩散模型和成本分摊模型对原油泄漏的补偿分配具有一定的指导意义。该模型可以在保证合作联盟稳定的前提下，保证成本分配的公平性。本研究构建的原油扩散模型和成本分摊模型对原油泄漏的补偿分配具有一定的指导意义。该模型可以在保证合作联盟稳定的前提下，保证成本分配的公平性。本研究构建的原油扩散模型和成本分摊模型对原油泄漏的补偿分配具有一定的指导意义。
