Based on the method of well-logging multiscale analysis, the multiscale characters and the fusion of logging curves under different scales are studied systematically to extract the multicycle features of strata and to establish the corresponding relation between logging data and strata and therefore the improved logging data can be better applied to the evaluation of sequence stratigraphy. Based on the multiscale analysis theory of wavelet, single logging curve is processed through multiscale analyzing.

One has proved that the viewpoint that the horizontal sidetrack is the most important technology for exploiting "large scale"unswept remaining oil in mature oilfields from three aspects.They are:(1) the horizontal sidetrack is the main technology for exploiting primary rich areas of"large scale"unswept remaining oil in mature oilfields;(2) the horizontal sidetrack can hit any rich area of"large scale"unswept remaining oil in reservoirs;(3) the cost of the horizontal sidetrack is more low in contrast with the vertical well and the conventional horizontal well.

针对传统的边缘检测方法因卷积运算造成模糊图像边缘，且对噪声敏感，各种形态学边缘检测方法因检测到的边缘信息类型不同而容易使边缘信息丢失，提出一种组合式抗噪型形态学边缘检测算子；并利用不同尺度的结构元素具有不同的图像边缘检测效果，进行形态结构元素的尺度调整，得到不同尺度结构元素下的图像边缘位置；然后进行加权合成来获得边缘图像；实验表明，与其他的传统或者形态学边缘检测方法相比，该文方法不仅具有更好的噪声抑制功能，而且其检测到的边缘轮廓更加清晰完整，边缘细节更加丰富。

为了弄清这些问题，笔者通过小波多尺度分析理论模型数据和实测数据进行分解处理，对比了向上延拓和小波多尺度分析方法在磁测资料处理中的应用效果，证明了磁异常小波多尺度分解方法对矿山的深部找矿具有积极的作用。

For the coarsest scale there are fewer local minima and further apart from each other. Thus, at the coarsest scale linearized methods can get closer to the neighborhood of the global minimum, and its final result is implemented as an initial model of the inverse problem of the second coarsest scale.

大尺度上反问题的目标函数局部极小少而且互相分得很开，因而用常规的反演方法可以较容易地收敛到全局极小的邻域内；将大尺度的解当作次一级尺度反问题的初始模型，再进行反演。

A new implicit pressure calculation method and relevant percolation rule are introduced taking account of the advantages of methods suggested by King, Sorbie and Stenby. Simulation methods for various boundary conditions (fixed pressure or fixed flow rate) and well pattern (line drive, five-spot pattern) are presented.
