This study made a conclusion ? amely in order to realize following the geological target while drilling, on the basis of making a better geological and drilling design for horizontal well, we must make full use of mwd, lwd and integrate logging to carry out lithfacy identifying in real time, the lwd interpretation and formation evaluation, to set up geological model of target formation, to select geosteering marked formation and compare simulative curves with lwd curves f to fix on the drilling direction of bit upper and declination, the position in target oil - gas layer, to revise borehole track in real time, to make it extend in reservoir better interval as possible
研究認為，在做好水平井地質設計和鉆井設計的基礎上，要實現隨鉆跟蹤地質目標鉆井，必須充分利用隨鉆測量、隨鉆測井和錄井等資料，從實時巖性識別、隨鉆測井解釋和地層評價、目標層地質模型建立、導向標志層的選取及模擬曲線對比等方面入手，確定鉆頭上下傾鉆進方向及在目標層中的位置，以實時調整井眼軌跡，使其盡可能在儲層物性較好的部位延伸。 -
The future wireless mobile communication systems are expected to provide ubiquitous, high - quality, and high - rate mobile multimedia transmission. however, hostile multipath fading radio conditions give rise to serious inter - symbol interference ( isi ) ; even worse, wireless channel are often time varying, which makes the system more vulnerable and more difficult to track the channel state. orthogonal frequency dvision multiplexing ( ofdm ), which is inherently resistant against isi, has invoked a popular research interest in recent years, and has been a promising candidate technology of the physical layer for future weideband high - date - rate wireless communications. notwithstanding, ofdm is much more vulnerable to errors of both time and frequency synchronization and to that of channel estimation, and how to obtain correct timing and channel estimation efficiently is highly critical to ofdm systems. the dissertation will focus on both of the aspects of ofdm systems mentioned above
但是無線環境的多徑特性造成通信系統中嚴重的符號間干擾，同時無線通道的時變性使得通道特性跟蹤復雜。而正交頻分復用技術（ orthogonalfrequencydivisionmultiplexing ， ofdm ）正是一種解決符號間干擾的有效傳輸手段，因此ofdm技術作為未來寬帶高速率無線通信的物理層候選技術在當前引起了一股研究熱潮。但ofdm系統對定時同步誤差和通道估計誤差非常敏感，如何在ofdm系統中準確快速地實現符號同步和通道估計是至關重要的，本論文將重點針對這兩個問題進行討論。 -
In the present, the models used widely are two kinds : the continuous model. the continuous model is supported by " smearing out " the discrete support along the track. giving a continuous viscoelastic foundation and a continuous layer represent sleepers
目前所使用的計算模型主要分為兩種：一種為連續型模型：將沿軌道方向的離散支撐連續化，將枕木模擬為剛體或為有均布質量和剛度的梁，使枕木成為粘彈性地基上的連續層。 -
