water injection test

Based on the measurements of the conductivity and the Cl-concentration in water samples, the standard fitting curves of instantaneous injection method of radial convergent flow was hired to obtain the dispersion parameters of unconfined aquifers in test sites.

在对水样进行电导率及Cl-浓度测试的基础上，使用径向收敛流场瞬时注入标准曲线配线法求得试验场地潜水含水层的弥散参数。

Studied the water shutoff method, witch pre-treatment formation with high concentration of polymer, optimize water shutoff parameters by means of perpendicularity test, including mass fraction of polymer, intake volume of polymer, injection rate of polymer and permeability.

研究了用高浓聚合物预处理地层的堵水方法，正交试验法优化了堵水参数，包括高浓聚合物质量分数、高浓聚合物注入量、注入速度和地层渗透率极差。

TEST STUDY ON COUPLING RELATIONSHIP BETWEEN PERMEABILITY CHARACTERISTICS AND STRESS OF OUTBURST COAL The effect of water injection on horizontal terrestrial stress in low permeability reservoirs

突出煤渗透特性与应力耦合试验研究低渗透油藏注水对水平地应力的影响

The water injection in coal seam to prevent rockburst has lower costing, simper operation and better availability, which is always the first selected measure. However, there is not a relative research result and it stops at test level.

煤层注水预防冲击地压成本低、操作简单、适应性强，一直是预防冲击地压的首选措施，但过去缺乏相应的研究，以至迄今仍停留在试验水平上。

Both kinds of formations were tested with much lower oil production and water injection capabilities. There was almost no oil produced from most formations in the test for oil.

两套储层的自然产能和吸水能力都非常低，多数层试油时不出油，采油指数和吸水系数都很低。
