In the paper , the geological mapping utilizing SPOT image is presented , and lineament pattern and its relationship with subsurface gas-bearing structure is discussed .

在某些压力和温度的条件下，储油构造中不出现气体。

Under certain conditions of pressure and temperature in the trap , no gas is present .

柴达木盆地有大量储油构造和良好的盖层条件，却缺乏足够的理想储集层，寻找裂隙性储集层分布区，很可能是实现该区油气勘探突破的关键。

Searching for fissure-type oil and gas traps is probably the key of petroleum exploration in Qaidam Basin , where oil seeps and anticlines are abundant but without enough ideal reservoirs .

小型或次级断裂以及由断裂产生的节理、裂隙等，可改善储层的性能，是该区各种储油构造形成的主要构造条件。

Small or second-order faults , and joints and cracks caused by faulting may improve the reservoir property , and are the major tectonic features that lead to the various structural trap of oil and gas in the region .

国内外利用激发极化法在油气藏上实测试验和实验室研究表明，深部储油构造引起浅层激电异常的主要地质因素是与油气藏上方浅部地层中的次生黄铁矿侵染带有关。

Laboratory induced polarization study and field induced polarization experiments conducted over hydrocarbon traps show that the key geological reason why deep hydrocarbon trap results in shallow induced polarization ( IP ) anomaly is the shallow secondary-pyrite contaminated zone that overlies the hydrocarbon trap .

结论盆地经历了多旋回沉积和多方式的后期改造，不同的构造组合形成了不同的储油气构造模式，对于盆地深层的油气勘探，特别是寻找隐蔽油气藏具有重要意义。

The basin undergoing multicycle sediment evolution and multi manner late-deformation and different structure combination forms different structural reservoir model . It is very important to recognize these for oil and gas exploration in deep basin , especially for the concealed reservoir exploration .
