【摘要】 根据深盆气藏形成和保存必须满足的力平衡约束和孔隙度约束条件,以及误差界约束,建立了计算深盆气藏在给定地史时刻平衡深度的非线性规划模型。基于地史数值模拟方法,通过引入分布预测目标区域在给定地史时刻深盆气藏分布矩阵,对网络控制节点逐点解该非线性规划问题,可实现以深盆气藏理论最大分布范围的动态预测。更多还原

【Abstract】 The formation conditions and distribution principle of deep basin gas are different from the typical hydrocarbon habitat.Its formation and conservation must meet the force and porosity constraint condition.A nonlinear programming model is given to decide the balance depth at fixed time,then the distribution matrix of a region at given time is introduced by solving the nonlinear programming point by point.With the method of geology numerical simulation,the dynamically developing character of deep basin gas can be described.Compared with the former model,the prediction result from our model is more robust because of the introduction of concept of error bound.更多还原
