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。

At the same time, the MEMS geophone can be used to monitor the microseismic event of coal mining, water reservoir and hydraulic fracturing through the research of failure location and the ratio of rock fracture can be predicted by counting numbers of acoustic emission.After spent six months to monitor injecting microseism in Ying 11 block of DongXin field using this system and collect abundant microseismic wave files. The result showed that the orientation of injecting fracture was mainly NE90°to NE125°. The maximum horizontal principal stress directions were mainly distributed in NE90°-NE130°range. Analysis of numerical simulation result of reservoir stress in Ying 11 block showed that the maximum horizontal principal stress directions are approximate east-west in central and western region and approximate NE130°at eastern border.

利用该系统对东辛油田营11进行了六个月现场注水微震监测，对监测数据的处理表明营11注水区域裂缝发育方向基本上为NE90°-NE125°；同时营11地区油藏地应力数值模拟结果分析表明其水平最大主应力的方向主要分布在NE90°-NE130°的范围内，研究范围中西北区块的水平最大主应力方向近似为东西向，研究区块的东部边界的水平最大主应力方向近似为NE130°左右，模拟结果与裂缝监测方位相符较好，两者结合给出了这个地区合理开发部署建议。

The value of the minimum stress is one of the most important parameters in hydraulic fracturing.
