柯克亚卡拉塔尔凝析气藏构造特征研究

Research on Structure Characteristics of Kalataer Formation in Kekeya Condensate Oil and Gas Reservoir

通过构造演化特征﹑地震属性特征﹑烃类检测综合分析对柯克亚卡拉塔尔凝析气藏的构造特征进行了研究。研究结果表明,柯克亚卡拉塔尔组灰岩顶面构造主体范围内发育3排由东南至西北受近东西走向逆断层控制的小构造,第1排与第3排小构造附近油气更加富集,其中第3排小构造已被柯深102井证实富含油气,第1排小构造油气勘探潜力较大。

In order to promote further exploration of the Kekeya condensate oil and gas reservoir,the features of structureal evolution,seismic attribute and hydrocarbon are analyzed.The results show that in the main range of the top limeston structure of the Kalataer formation,there are three rows of small structures controlled by the nearly East-West thrust fault from the southeast to the northwest. The first and the third rows are rich in oil and gas.The third row is proved to be rich in oil and gas in Well Keshen 102.So the oil and gas exploration potential in the first row is great.
