運用化分散為集中的思想，把所有的井點都放在同一個單位網格內考慮.在坐標可平移、旋轉的條件下，利用尋找點群、有限步驟搜索法，對鉆井布局的三個問題進行了解答.對問題一，給出了兩個不同演算法.並對題目提供的數據進行了求解，演算法1得到的結點為（ 0 . 361 ， 0 . 461 ） ，最多有4個舊井點被同時利用，它們是第2 、 4 、 5 、 10個井點;演算法2得到的結點為（ 0 . 390 ， 0 . 505 ） ，最多有4個井點被利用，它們是第2 、 4 、 5 、 10個井點.對問題二，以結點為中心旋轉一定的角度后，歸結為問題一進行求解，求解結果為當網格傾斜角為0 . 78弧度（相對原坐標系） ，結點平移到（ 0 . 75 ， 0 . 076 ）點（在新坐標系下） ，可被同時利用的最多舊井點為6個，它們是第1 、 6 、 7 、 8 、 9 、 11個井點，對問題三，我們給出了充要條件，並給出了演算法.最後還分析了演算法的優劣性The example in the end of the paper shows the method is right and reliable
文章最後的實例計算表明，本文提出的水平井待鉆井眼軌跡最優化設計方法是正確的、可靠的。The surface of natural fracture ( crack ) is parallel to the orientation of maximum principal stress. the principle orientation of anisotropic permeability reservoirs agrees with the orientation of the maximum principle stress. many engineering problems ( e. g. bore - hole stability, casing deformation failure during drilling, reasonable arrangement of wells, the optimum design of hydraulic fracture and so on ) are influenced by the in - situ stress orientation
天然裂縫面和裂隙面與最大主應力方向平行；在各向異性低滲透率油田中主滲透率方向與最大水平主應力方向趨向一致：在鉆井過程中井壁穩定性，套管變形和損壞，油田開發井網合理布置、水力壓裂優化設計等都與地應力方向有關。Well trajectory for non - straight wells, which includes directional wells, horizontal wells, siedtracking and / or horizontal wells, long - reach wells and multibranches, is one of key techniques in non - straight drilling. the main results, obtained in this dissertation, may be summarized as follows
本文以石油工程中的非直井（定向井、水平井、側鉆井、側鉆水平井、大位移井、分支井）軌跡控制為背景，研究了一類約束優化與最優控制問題。The paper introduces the nonlinear programming method under nonlinear constraints to well trajectory design while drilling and puts forward an optimization method for well trajectory design
本文將非線性不等式約束下的非線性數學規劃理論引入到水平井待鉆井眼軌跡設計中，提出了水平井待鉆井眼軌跡的最優化設計方法。分享友人
