英文
hole size-
Abstract : tight trips often occur for hole undergauge during drilling in east sichuan oilfield. the paper analysis the causes of hole undergauge, proposes preventive and treatment measures which are to optimize design from geologic structure features, to use suitable fluid column pressure, to select different drilling fluid types, to adopt advanced drilling technology and perfect field technical management. therefore, good economic benefit will be obtained
文摘:川東構造在鉆探作業中因井眼縮徑造成起下鉆的阻卡時有發生，文中對造成井眼縮小的原因進行分析並劃分為五類因素，提出應在地質構造特徵方面優化設計，採用合適的液柱壓力，選擇不同的鉆井液類型，使用先進的鉆井工藝和完善現場技術管理等措施進行預防和處理，將取得重大的經濟效益。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。Especially the perforating technology in the exceptional horizontal wells such as slim - hole casing wells, large hole wells and complex wells is detailed
