basal water

Low temperature, high porosity and permeability, strong alkali sensitivity, loose limestone, circulation loss and basal water abundance are the formation characteristics of shallow reservoir in Taobao viscous oil area.

套保稠油区块油藏埋深浅，油层温度低、孔隙度和渗透性高、碱敏性强、岩性疏松、底水丰富，且存在漏层。

Changes in biomass increment, plant height, and basal diameter with water gradient reflected the slow-growing attributes of the seedlings.

生物量、株高和基茎增量的变化反映了沙地柏生长的缓慢性。

This paper introduces the basal theory of water demand side-management. Founding on the view of sustainable development, this paper comes up with a series of countermeasures to sustainable utilization of water resources.

针对这一情况，介绍了水资源需求侧管理的基本理论，并引入可持续发展的观点，提出了加强水资源需求侧管理的一系列对策和措施。

Taking HB braided river massive reservoir with strong basal ground water as an example, the paper discusses the deliverability decreasing methods of similar reservoirs and develops the curves.

以HB辫状河强底水块状油藏为例，探讨了同类油藏特征下产能递减规律，建立此类油藏产能递减典型曲线。

The results show that the effective factors include the formation pressure, the energy of basal water, the pressure sensitivity and etc.

结果表明，影响采出程度的因素包括地层压力、底水能量和应力敏感等。

Share of reservoir with basal water in the reservoir is large, and reserve volume is rich.

底水油藏在我国油藏中所占比例较大，储量丰富。

Two methods, i.e.integrated factor method and correlativity method for recognizinghydrochemical features of basal water and water gush source are introduced in this paper.

本文论述了识别主要含水层水化学特征和突水水源的二种方法，即综合要素法和灰色关联度法。
