1.
The conventional testing tool and tech are difficult to be successful in high pressure and low percolation formation.
常规地层测试工具和工艺难于在高压低渗地层中施工成功,通过对工具结构和工艺特点的分析,提出了适应高压低渗地层的测试工具组合和施工工艺,并在新疆西部的许多高压低渗深井的测试中取得良好效果。
4) High-pressure and low-permeability
高压低渗
1.
Because of weak pressure conductive ability in high-pressure and low-permeability reservoir,pressure builds up slowly when the oil well shut down,and well killing fluid density,according to formation pressure,is higher,resulting in formation damage.
由于高压低渗裂缝性储层导压能力较弱,关井后压力恢复缓慢,因此根据地层压力确定的压井液密度偏高、易造成储层污染,通过对储层压力恢复速度进行分析,确定出适用于不同压力恢复速度和施工周期的压井液密度,现场应用后取得了较好的油层保护效果和经济效益,并为同类储层压井液密度的选择提供了良好的借鉴。
5) low permeability and high pressure
低渗高压
1.
This paper analyzes the difficulty of the cementing of tertiary infilling of the major oil fields of Daqing Oil field and proposes the relation among the reservoirs with low permeability and high pressure, casing damage and water injection after casing damage and the effect of gas reservoirs and foam flooding on cementing quality.
分析了大庆主力油田三次加密井固井的难点 ,提出了低渗高压层、套损及套损后注水之间的关系以及气层、泡沫驱油等对固井质量的影响。
6) High-low permeable gas formation
高、低渗气层
补充资料：低渗溶液
低渗溶液
hypotonic solution
低于人血浆渗透压的溶液。人血浆渗透压为0.71kPa。通常以此为标准来衡量溶液的渗透压，低于此标准的溶液被称为低渗溶液。主要用于高渗性脱水的病人。
