The phase of rift basin formed the primary source rocks and reservoir and seal. Triassic-Jurassic Pucara Group and Cretaceous Chonta Formation generated a mass of hydrocarbons in Paleocene-Eocene (60-45Ma) and Miocene (15-5Ma), respectively.

盆地内主要的烃源岩及储、盖组合均发育在裂谷盆地阶段，三叠系—侏罗系Pucara群和白垩系Chonta组2套主要烃源岩的排烃高峰期分别是古新世—始新世（距今60～45 Ma）和中新世（距今15～5 Ma）。

By using these "ranking" and "unranking" algorithms, any permutation that is positioned in lexicographic order, away from a given permutation by any specific distance, can be generated. This significant benefit is the main difference between the proposed method and previously published alternatives.

藉由此个演算法，我们可以产生一个n项目的排任意距，依字母大小序而言，的另一个排；此特点是我们的方法与其它研究最同的地方。

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。
