鄂尔多斯盆地召黄庙地区断层对气水分布的影响

鄂尔多斯盆地召黄庙地区部分气井产水严重，影响了苏里格气田新区建产效果，有必要开展气水分布规律再认识。通过高精度全数字三维地震采集和处理解释一体化技术的应用，重新刻画了该区构造，分析断裂与气水分布的相关性，总结了气水分布模式。研究表明：召黄庙地区共发育有58条直立逆断层，北北西向断裂垂向多断至盒6层段附近、北东向断裂断穿石千峰组。西部断裂带以西构造低，产水严重；中部的断鼻圈闭气水共存，东部断裂发育规模小，气井生产效果好。召黄庙地区气水分布除受生烃强度控制外，还受到断裂带的影响，较之以往准连续型致密砂岩气体分布模式更为复杂。研究成果对类似气区的富集区筛选和井位部署具有重要的借鉴意义。

Influence of structural characteristics on the distribution of gas and water of He8 formation in the Zhao Huang temple area, Ordos Basin

The water production of some gas wells in zhaohuangmiao area of Ordos Basin is serious, which affects the construction and production effect of Sulige gas field new area. It is necessary to further understand the distribution law of gas and water. Through the application of high-precision full digital 3D seismic acquisition and processing interpretation integration technology, the structure of the area is redepicted, the correlation between faults and gas water distribution is analyzed, and the gas water distribution mode is summarized. The results show that: there are 58 vertical reverse faults in zhaohuangmiao area, most of the N-NW fault are located in the he 6 Formation, and the NE faults are located in Shiqianfeng Formation. In the west zone of the west fault is lower structure and product water serious ; in the fault nose trap which is in the middle area, gas and water is coexistence, the gas well production is better. The distribution of gas and water in zhaohuangmiao area is not only controlled by hydrocarbon generation intensity, but also affected by fault zone, which is more complicated than the previous gas distribution model of quasi continuous tight sandstone. The research results have important reference significance for the enrichment area screening and well location deployment of similar gas areas
