得到的主要結果為： （ 1 ）基於彈性地基理論和彈性梁的撓曲線理論，給出了管道在固定墩（相當跨越河溝情況）和無固定墩（相當坍塌和沖溝情況）的變形微分方程，並分析了當量軸力為拉力或壓力時管道的變形和受力情況。Abstract : according to sidewall unstable problem during dr illing, the study on sidewall stability is developed. the paper analyses sidewall stress state and sidewall unstable type, and combines with log data and indoor e xperimental result of core. through analysis and calculation, the method of calcul ating slough formation pressure is proposed. by application of the method in 3 wells in yancheng area, result shows that slough pressure section fits in with field practical condition. it supplies some basis for design of drilling fluid d ensity
文摘:針對鉆井中井壁失穩問題開展井壁穩定性研究，文中就井壁應力狀態和失穩類型進行分析計算，並結合測井資料和巖心的室內實驗結果進行分析，建立了一套計算地層坍塌壓力的方法，結合鹽城地區3口井應用對比，坍塌壓力剖面基本吻合現場實際，為鉆井液密度設計提供了一定的依據。Using logging information can make the size and direction of in - situ stress, and then determine fracture pressure and breakout pressure so can provide the suitable mud density to solve the mechanics instability of borehole
用測井資料可以確定地應力的大小和方向，從而確定地層破裂壓力和坍塌壓力，並給出合理的泥漿密度，解決井眼力學失穩問題。This thesis integrates the borehole collapse model with the artificial fracture and imaging well logging to get the size and direction of in - situ stress, and set up the reasonable prediction model of fracture pressure and breakout pressure for carbonate profile, by making use of the rock mechanics parameters from logging information, based on comparing the present various prediction models
本文在此綜合應用井眼崩落法、人工壓裂法和成像測井法以確定地應力的大小和方向，並在分析比較國內外各種地層破裂壓力和坍塌壓力預測模型優缺點的基礎之上，從測井資料中提取多種巖石力學參數，建立了適合於碳酸鹽巖地層的破裂壓力和坍塌壓力預測模型。Based on the above methodological analyses and practical situation of feixianguan interval in the luojiazhai and dukouhe structure on the east of sichuan, a set of well log interpretation formation pressure application program is developed. it has been successfully applied to the fine interpretation of luojia4 well and du4 well, and so on. the results of formation pore pressure, fracture pressure and breakout pressure are all accordant with the practical situation
在上述方法理論研究的基礎上，結合川東羅家寨和渡口河構造飛仙關組地層的實際情況，編制了一套適合於該研究工區的地層壓力測井解釋應用程序，並用於羅家4井和渡4井等井的測井資料精細處理中，所計算的地層孔隙壓力、坍塌壓力和破裂壓力與實測資料相符，且所確定的鉆井泥漿密度窗得到了實際生產的驗證，達到了預期效果。Abstract : in some project, pebble is used in bearing stratum. for the resean of lower strengthand bad property of construction. the bearing capacity of pebble can ' t achieve the reauirement of up - structure. but the pebble soild has higher permeability coefficient and placeability. the method has remarkable economic results
文摘:在以礫卵石層為持力層的樁基設計中，由於其可鉆性差、易坍塌，強度相對較低，但是具有較大的孔隙率和滲透系數，可灌性較好，採用一定壓力對鉆孔灌注樁樁底礫卵石持力層注入水泥漿液對其進行加固處理，可以較大地提高其承載力，並能取得較為明顯的經濟效益。It is also used to prevent or solve geologic calamity, such as landslide and rock collapse etc. in addition, it is also used to drill small size water well and hige - pressure jet grouting hole
