【摘要】：大位移井鉆井過程中對環(huán)空堵塞能量的計算對于校核鉆機設(shè)備能力或選擇、升級改造鉆機設(shè)備,優(yōu)化大位移井井眼軌道設(shè)計等具有重要作用。以前的研究只是定性的指出這方面的問題。本題目從水力能量入手,結(jié)合井塌、沉砂、砂橋、巖屑床等井下復雜情況,建立了清除環(huán)空堵塞物所需水力能量的計算模型,并提出了處理上述復雜情況的具體措施,從而找出解除環(huán)空堵塞的方法,達到消除因坍塌、沉砂、砂橋、巖屑床引起的井下復雜情況。論文根據(jù)所建立的數(shù)學模型,編制了處理環(huán)空堵塞所需水力參數(shù)優(yōu)化設(shè)計程序。論文通過軟件進行實例計算,對兩口井的井眼環(huán)空堵塞所需水能量狀況進行了分析評價。
[Abstract]:The calculation of the clogging energy of annulus in the drilling process of extended reach well plays an important role in checking the capacity or selection of drilling rig equipment upgrading the rig equipment and optimizing the design of borehole track. Previous studies have merely qualitatively pointed out this problem. Starting from the hydraulic energy and combining the complex conditions of well collapse, sand sinking, sand bridge and cuttings bed, the calculation model of hydraulic energy needed to remove the clogging material in annulus is established, and the concrete measures to deal with the above complex situation are put forward. The method of removing the clogging of annulus is found to eliminate the complex situation caused by collapse, sand sinking, sand bridge and cuttings bed. According to the established mathematical model, the optimal design program of hydraulic parameters for the treatment of annular blockage is worked out in this paper. The paper analyzes and evaluates the water energy situation of the two wells in the annular hole plugging by the example calculation of the software.
