摘要: 2005 年吉林油田在长岭断陷的中部凸起带发现长岭气田营城组火山岩气藏。该区火山岩储层岩性、岩相复
杂、非均质性强,裂缝比较发育、底水体积大、能量强,给气藏开发带来了较大困难。为了有效开发长岭气田火山岩气
藏,通过深化地质认识,开展有效开发方式论证,确立了水平井开发方式,并通过水平井的优化部署及现场地质导向,
实现了储量的高效动用,水平井成功率100%、气层钻遇率达到92% 以上。

Abstract: Jilin Oilfield company discovered Yingcheng Formation of Changling Gas field in the middle platfood of Changling
rift. The volcanic reservoirs are characterized by complex lithologies and lithofacies,and extremely serious heterogeneity,
with well developed fracture,large volume of bottom water,and strong energy,which is difficult for the development of gas
reservoirs. To develop the Changling gas field volcanic gas reservoir,after obtaining a better understanding of geognosy,and
analysis of effective way of development,we established the developing style of the horizontal wells. By the optimization of
deployment and on-site geological orientation,the efficient employment of the reserves have been achieved,the success rate
of the horizontal well being 100%,gas drilling rate more than 92%.

Key words: Changling gas field, volcanic, fracture, horizontal wells, development techniques
