Experimental study on evaluation of formation drillability anisotropy by acoustic wave velocity
用聲波法評價地層可鉆性各向異性的實驗研究 -
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。 -
On relation between rock drillability and formation pore pressure from log data
巖石可鉆性與地層孔隙壓力關系的測井研究 -
This essay adopts the neural network and some parameters regression analysis to set up the some logging parameters prediction model of the rock drillability, then gets the continuous drillability classification value of single well formation. and deduces the theoretic relation of the formation pore pressure and the rock drillability creatively
本文採用神經網路法與多元回歸分析法建立了巖石可鉆性測井多參數預測模型及單井地層的連續可鉆性級值剖面，同時創造性地推導了地層孔隙壓力與巖石可鉆性之間的理論關系。
