Meanwhile, it could be seen that there does not exist a confidence interval with width less than 0.5 because of the property of Poisson distribution. Based on these conditions, the author mainly carried out research into two aspects of this problem as follows. Firstly, by numerical and theoretical analysis, the author compares some existent confidence intervals, for example,"exact" confidence interval, Wald confidence interval and Bayesian confidence interval, and finds some deficiencies points of the confidence intervals, whose modification version has been proposed .Also, several better confidence intervals such asare also presented .Secondly, for given confidence coefficient and interval width, the author constructs a class of asymptotical two-stage interval estimate procedures. At the same time, under varies restriction of confidence coefflcientent interval width, the optional sample size of the first stage has been computed by numerical computation. The numerical computation shows that the method considered in this dissertation have good properties and applied value.

同时，由于Poisson分布的特性，我们知道不存在其参数区间长度小于0.5的置信区间，基于这些情况，我们主要展开了以下两个方面的研究：一是利用数值计算分析与理论分析的方法对现有的若干置信区间如"精确"置信区间，Wald置信区间，Bayes置信区间等进行分析比较，发现了一些缺陷，针对这些缺陷，我们进行适当的修正，并得到几种性质较好的置信区间如：修正大样本区间Jeffreys原则下置信区间二是针对已给定的置信系数与区间长度，我们提出了一种渐近的两阶段区间估计程序，并利用数值计算的方法，在各种置信系数与区间长度限定下，算出了最优的第一阶段观测次数，大量数据表明，本文考虑的方法性态良好，具有应用价值。

Therefore,tapping potencial of remaining oil to improving oil recovery,the recognition of reservoir intraformational heterogeneity in channel sandbodies is proposed and the main targets of reservoir IOR in channel sandbodies of mature oilfields are pointed out as follows:①shutting off strongly-waterflooded intervals to control ineffective circulation of injected water;②strengthening water washing in medium-waterflooded intervals in order to achieve the aimed waterflood efficiency and even to exceed it;③enhancing injection-production consistency and injector-producer ratio of non-waterflooded or weakly-waterflooded intervals for the propose of realizing effective displacement and imporving conforma nce.

根据我国东部主力油田储层绝大多数都属于河道砂体，注水开发进入高含水阶段后，层内剩余油超过层间剩余油，层内矛盾上升为主要矛盾这一特点，从挖掘层内剩余油潜力出发，提出要重新认识河流砂体储层层内非均质性，并指出高含水期河流砂体储层改善采油目标主要有：①封堵强水洗段，控制注入水无效循环；②加大中水洗段注水冲洗强度，达到目标水驱效率，并有可能超过目标效率；③提高未、弱水洗段的注采对应程度和注采井数比，达到有效驱替，提高波及程度。

There are track intervals and there are road intervals, and both types of intervals come in a variety of flavors.

有场地间歇，也有公路间歇，这两种间歇模式的感觉有一些不同。
