1) sandstone gas reservoir
砂岩气藏
1.
When the sandstone gas reservoir is drilled open by the underbalanced drilling using water based mud (WBM), the underbalance pressure normally can hardly offset the imbibition capillary force of the rock, which may result in backwash imbibition.
这种自吸效应可能对砂岩气藏水基欠平衡钻井的储层保护效果产生影响,但目前与之有关的实验研究还很缺乏。
2.
针对新场气田蓬二段低渗透砂岩气藏一次调整后采出程度仍较低的开发现状,采用地质和气藏工程方法分析气藏加密调整的可行性,选择试验区块并采用数值模拟方法进行井距论证和开发指标预测。
2) sandstone reservoir
砂岩油气藏
1.
Acidizing is one of the most effective EOR methods used in sandstone reservoirs.
酸化是砂岩油气藏最有效的增产措施之一。
3) Sand reservoir
砂岩油气藏
4) sandstone lithologir hydrocarbon reservoir
砂岩岩性油气藏
5) tight sand gas
致密砂岩气藏
1.
The tight sand gas is one of unconventional gas, it is also an important candidate resources of conventional gas.
在总结前人研究的基础上,结合构造演化历史背景,动态的研究致密砂岩气藏烃源岩生排烃高峰期与储层致密演化史二者之间的关系,将致密砂岩气藏划分为两种类型:储层先期致密深盆气藏型(“先成型”深盆气藏)与储层后期致密气藏型(“后成型”致密气藏)。
6) unconsolidated sandstone gas reservoir
疏松砂岩气藏
1.
Study on sanding mechanism of unconsolidated sandstone gas reservoir;
疏松砂岩气藏出砂机理与实验研究
2.
Well test analysis of unconsolidated sandstone gas reservoir in consideration of stress sensitivity
考虑应力敏感疏松砂岩气藏试井分析
3.
Hence, it is proposed to allow an appropriate amount of sand production during recovery of unconsolidated sandstone gas reservoirs.
疏松砂岩气藏在开采过程中容易出砂,采取完全防砂的方式进行开采,既增加了气井的成本,又降低了气藏的开发速度。
补充资料：粉砂岩
| 粉砂岩 siltstone 由粒径为0.0625～0.0039毫米（mm）的粉砂的含量占50％以粉砂岩标本的一种碎屑沉积岩。除粉砂以外其它由砂、粘土或化学沉淀物组成。按粒度划分为粗粉砂岩（0.0625～0.0312mm）和细粉砂岩（0.0312～0.0039mm）。按碎屑成分划分为石英粉砂岩、长石粉砂岩、岩屑粉砂岩（少见）和它们间的过渡类型。根据胶结物成分划分为粘土质粉砂岩、铁质粉砂岩、钙质粉砂岩和白云质粉砂岩。黄土也是一种疏松的或半固结的粉砂质沉积物。粉砂岩多形成于河漫滩、三角洲、潟湖和海洋的较深水部位。
