The distributary river course reservoir in the Lower Member of Minghuazhen Formation in an oilfield of Bohai Basin was modeled. The modeling units were divided using the integrated geological modeling method based on seismic, log and geological data. The sedimentary microfacies features of the modeling units were described. The geological knowledge base, including quantitative description of microfacies in every unit, probability function of facies, connection probability of sand body, was established. The geological model of reservoir was proposed on the basis of stochastic reservoir modeling by using an objectbased simulation method.

The projection gradient method will be a possible way to solve the problem that we just get. It has been shown that the projections of the every directions, of which is the boundary point in linear restraint problems, are the possible decent directions, and the projection of negative grads direction is a decent direction. In 1960, Rosen proposed the basic idea of projection gradient methods, and then lots of researchers have been tried to find the convergence of this method. But most of them get the convergence with the condition to amend the convergence itself.

在约束最优化问题的算法中怎样寻找有效的下降方向是构造算法的重要内容，在寻找下降方向方面可行方向法中的投影梯度法有效的解决了下降方向的寻找问题，利用线性约束问题边界点的任意方向在边界上的投影都是可行方向，而负梯度方向的投影就是一个下降方向。60年代初Rosen提出投影梯度法的基本思想，自从Rosen提出该方法以后，对它的收敛性问题不少人进行了研究，但一般都是对算法作出某些修正后才能证明其收敛的，直到最近对Rosen算法本身的收敛性的证明才予以解决。

Until recently, the convergence of the Rosen"s arithmetic has been proved. The projection gradient method is the generalization of Steepest decent method to constraint problem. So it does have a faster convergence speed that the fastest decent method . To solve the problem, many researchers have generalizat the well-developed optimization with unconstraint to the Rosen"s gradient method. The conjugate gradient method is one of success to solve the problem.

投影梯度法是最速下降法对约束问题的推广，因此没有较快的收敛速度，为了解决这个问题很多中外学者把发展得比较成熟的无约束最优化算法作类似的推广，其中共轭梯度方法是近年发展的很成熟的方法，它具有计算简单，算法结构好，计算量少，具有良好的收敛性等优点，而Rosen投影梯度法的提出使寻找下降方向变得简单。

Those who so bind themselves, and are not rapacious, ought to be honoured and loved; those who do not bind themselves may be dealt with in two ways; they may fail to do this through pusillanimity and a natural want of courage, in which case you ought to make use of them, especially of those who are of good counsel; and thus, whilst in prosperity you honour them, in adversity you do not have to fear them.

对于那些这样约束自己而不是贪婪的人们，你应该给以光荣并加以爱护；而对于不是这样约束自己的人们，你可以从下述两种方式着眼进行检验。这就是说，他们这样做可能是由于胆怯或者天生缺乏勇气使然。在这种情况下，你应该利用他们，特别是利用那些能够给你提出有益意见的人们。因为，这样一来，当你隆盛的时候，他们会尊敬你，而当你处在逆境的时候，你也无需畏惧他们。
