盖层

A good cap layer is necessary to keep oil/gas validly in a reservoir.

摘要优质、良好的盖层是储集层保存油气必不可少的条件。

The surface soil and the unconsolidated mantle rock beneath it form only a thin venner.

The third parameter needed for an oil field to occur is the cap rock or seal.

形成油田所必须的第三个参数是盖层岩石或封闭层。

The estimated gravity anomalies of Puguang gas field based on the density of reservoir rock and cap rock are less than 1 mGal.

根据气田储层和盖层的岩石密度，估算普光气田上约有零点几毫伽量级的重力异常。

Erdos basin is our country gas reserves most areas and our country transport the natural gas from the west to the east most powerful production base, Has the reservoir wave impedance difference to be small but the cap rock to clamp the strong reflection coal bed and so on not to favor the seismic exploration the characteristic.

鄂尔多斯盆地是我国天然气储量最多的地区和我国西气东输的最强有力生产基地，具有储层波阻抗差异小而盖层夹强反射煤层等不利于地震勘探的特点。

The main factors influencing the gas preservation condition includes the fault amplitude, fault fragmented intervals, fault surface dip, and the position of fracture cavity system in the faulted zone.

大断裂影响缝洞系统保存条件的主要因素包括：大断裂断距、断层上消失层位、断面倾角、盖层厚度以及缝洞系统所处断裂带位置等。

Hydrocarbon source rocks are distributed in craton basins and in-tracratonic rift basins.

碳酸盐岩是主要的储集层，泥质岩是主要的区域和局部盖层。

Further, many hand-dug wells and oil seeps exist in the area, which suggests the presence of a favorable oil and gas movement zone worthy of exploration.

为了研究该区的勘探方向，笔者从区域构造和沉积演化入手，分析研究了该区的生油层、储层和盖层的沉积相带特征和有利的油气聚集带。

Petroleum systems in half-grabens extend along the slope, while petroleum systems in grabens are basically restricted between two boundary faults or extend slightly.

盆地早第三纪经历了3个裂陷期，均发育有烃源岩、储层和局部盖层，形成的含油气系统存在着依次改造相互叠加组合的关系。

Because the vines are shallow-rooted, they will benefit from a thick layer of organic mulch.

因为藤根浅，他们将受益于厚厚的一层有机复盖层。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
