At the same time, it states the dominant industry for each district, and defines growth pole of beijing suburbs on the basis of density of dominant industry and economical level for each district. finally, the paper demonstrates that it is necessary to build economy growth pole model of beijing suburbs on the beginning of 21s1 century on analysis of relations among dominant industry, growth pole and economic growth point, discusses evolvement rules about pole - core space structure phase. point - axis space structure phase and network space structure phase, analyses which space structure phase beijing suburbs is in, and brings forward point - axis developing model, then explains definition of point - axis developing model and important meanings for economy development of beijing suburbs, referring to principle of point - axis developing model, the paper proposes economy growth point model, and offer the policy and suggestion for government corresponding to the problems of application of economy growth point model
最後，通過論述主導產業、增長極與經濟增長點的相互關系，闡述了從產業和地區角度對主導產業和增長極進行綜合分析以構建21世紀初北京郊區的經濟增長點模式的必要性，探討了極核式空間結構階段、點軸式空間結構階段、網路空間結構階段這三種空間結構的演變規律，分析了21世紀初北京郊區所處的空間結構階段，提出了點軸開發模式，從點? ?軸開發的定義、對北京郊區經濟發展的意義進行了論述，進一步通過對點? ?軸空間結構系統的形成機理分析，借鑒點? ?軸開發的原理，提出21世紀初北京郊區的經濟增長點的構建模式，並針對這種模式構建中存在的問題，對政府工作提出了可行性建議。 -
Because of the merit of continuity, economical efficiency, reliability and high resolution, the well logging has shown its advantages, especially in some drilling engineering problem, such as the prediction of rock drillability, selecting the drill bit types, prediction of formation pressure, calculation the in - situ stress, evaluating the borehole walls stability and determining the reasonable mud density, and etc. aiming at the engineering accidents, for example the well spout, well leak, well collapse and the drill blocking during the drill engineering in the t formation in north - east of sichuan, some farther studies of formation pressure in feixianguan from well - logging information are presented in this dissertation
尤其是在巖石可鉆性預測與鉆頭選型、地層壓力預報、地應力計算以及井壁穩定性評價、泥漿密度安全窗確定等鉆井工程問題上。測井技術由於連續性、經濟性、可靠性及解析度高等特點，越來越多地顯示了其優越性。本文針對川東北部三疊系地層在鉆井過程中遇到的井噴、井漏、井塌和卡鉆等工程事故，主要對飛仙關組地層壓力的測井解釋方法作了大量的深入研究工作。
