中文拼音 [jǐngyǎnxìshǔ]
井眼系數
英文
well bore coefficient-
Secondly, by means of arranging and analyzing the construction monitor data, the practicality method of proposing the dewatering calculation model and parameters of the non - constantly pumping dewatering well was proposed, moreover the equivalent calculation model and parameters of the erhe project was proposed. thirdly, based on calculating the design scheme of dewatering well with the equivalent calculation model, the optimized scheme of dewatering well of the erhe project was proposed and the well number was reduced to 32 where it was 42 in the old scheme. at last, based on the well construction, the dewatering well structure and constructing technique in the soft soil area were exploited in addition, the significative analysis and evaluation attitudes to the old design scheme of dewatering well project were impersonally proposed
首先，根據工程地質及水文地質條件和工期分析，提出了「二河」降水井的設計方案；其次，通過系統整理分析抽水井的施工監測記錄，提出了用降水井的施工監測確定非定常抽水降水井井流模型和參數的實用方法，並建立和確定了「二河」降水井非定常抽水、有越流的完整潛水井等效模型和參數；接著，通過用等效井流模型進行降水井方案的計算，提出了「二河」降水井的優化方案，使原方案的42眼井降到32眼井；最後，通過對降水井成井施工實踐的總結，開發了適于軟土區的降水井結構和成井施工技術。What ' s more, the optimal solution cannot be guaranteed. according to the constraint nonlinear programming of designing horizontal trajectory presented by jiang shengzong in 2001, the paper constructs a nonlinear multilevel lumped parameter dynamical system by the nonlinear control theory and describes the existence of its solution and the controllability as well as the polykeys of this optimal control
2001年江勝宗等人提出了側鉆水平井軌道設計的約束非線性規劃，本文應用非線性控制理論，建立了三維水平井井眼軌跡的非線性集中參數多階段動力系統，論述了該系統解的存在性及其最優控制的可控性和多解性。Horizontal well production forecasting formulas need to consider not only anisotropism and borehole eccentricity, but also the skin factor during drilling and completion process
摘要水平井產能預測公式除了要考慮儲層各向異性和井眼偏心距的影響因素外，還要考慮鉆井和完井過程中產生的表皮系數的影響。
