摘要:

通过地层、沉积相、岩石学特征、储层物性和连通性等方面的研究,对库车坳陷克深2气藏和克拉2气田白垩系巴什基奇克组砂岩储层的气藏地质特征进行对比,发现克深2气藏与克拉2气田在地层和沉积相方面具有较好的关联性,但在储层特征方面具有较大的差异,具体表现在长石含量、物性特征、隔夹层和裂缝及断层的发育情况有较大的不同。通过对比研究,相对于克拉2气田,克深2气藏整体上储层物性和气藏连通性较差,在后期需要借鉴克拉2气田成熟的开发技术和地质资料进行高效有序的气田开发。

Abstract:

The geological features of sand reservoirs in Bashijiqike Formation in Keshen2 gas field in Kuqa depression were contrastively studied with those in Kela2 gas fieldthrough analysis of sequences, sedimentary facies,petrophysics,reservoir property and reservoir connectivity. The results reveal that the sequences and sedimentary facies in the two gas fields have good relationship, but their reservoir characteristics are much different, especially in the content of feldspar, petrophysics, and development of interlayers, fractures and faults. Combined with Kela2 gas field, the reservoir propertyand connectivity in Keshen2 gas field are not well, and the gas field is in the initial process of exploration and development, therefore it is essential to use for reference from the abundance geological data and perfect development technology in Kela2 gas field.

Key words: Keshen2 gas field, Kela2 gas field, Kelasu tectonic zone, geological characteristic, communication in gas field
