This is the so-called Duerlite algorithms: from the bottom row of the matrix A do elementary transformation, the diagonal elements into the bottom left of zero, and then show the effect of these lines is equivalent to transform the left by a unit lower triangular matrix, this series of unit lower triangular matrix inverse is the product of L matrices, it is also a unit lower triangular matrix.

这正是所谓的杜尔里特算法：从下至上地对矩阵A做初等行变换，将对角线左下方的元素变成零，然后再证明这些行变换的效果等同于左乘一系列单位下三角矩阵，这一系列单位下三角矩阵的乘积的逆就是L矩阵，它也是一个单位下三角矩阵。

Comparing with traditional LU numerical decomposition algorithm to solve each row of lower triangular matrix L and each column of upper triangular matrix U, the proposed method is easy to program and efficient In addition, the structure symmetry of Jacobian matrix and the experience of compiler optimization are also adopted in this research, it makes less required memory for the proposed algorithm and higher calculation efficiency.

这种算法和求取L阵每列和U阵每行的传统LU分解方法相比，具有编程简单、计算效率高的优点。另外，雅可比矩阵结构对称以及编译器优化的经验也应用到文中，使得算法不仅占用内存较少，且效率较高。

Therefore, the early use of low-permeability reservoir development Diamond Anti-9:00 Well, diamond crack parallel to the main diagonal directions along the crack edge wells to increase water efficiency by the degree of widening further suppress the injection wells, well away from the row Kadoi premature flooded, and the overall benefit of fracturing; in the latter part of the diamond-shaped anti-9:00 Well Well turn the corner to form staggered rows like water injection means, thereby maintaining a high production rate and phase out the extent of mining.

因此，低渗透油藏开发初期使用菱形反九点井网，菱形主对角线平行裂缝方向，沿裂缝注水增加边井受效程度，拉大的井距又可抑制注水井排的角井过早水淹，且利于整体压裂改造；中后期将菱形反九点井网的角井转注形成交错排状注水方式，从而保持较高的采油速度和阶段采出程度。
