摘　　要：黄骅坳陷风化店地区已开发的砂岩油层组已进入开发中后期,寻找新的潜力油气藏迫在眉睫,相邻区块辉绿岩油气藏的发现,使风化店地区火成岩油气藏得到关注。该地区火成岩油气藏规模较小,有利目标区难以明确,针对这一问题,从火成岩及其蚀变带的分布入手,在详细分析录井显示的基础上,对火成岩储集层电性、岩性及物性特征进行了评价,通过研究火成岩侵入带与孔二段油气藏的关系,发现Z111断块高部位井区可作为油气开发的有利目标区,明确了该地区进一步勘探的方向。The developed sandstone oil group in Fen- ghuadian area of Huanghua Depression has entered into middle-late development period,to find new potential oil and gas reservoir has been extremely urgent.Due to the discovery of oil and gas reservoir in diabase of the adjacent block,the attention was paid to the igneous oil and gas res- ervoir in Fenghuadian area.The scale of the igneous oil and gas reservoir of the area was small,the favorable target are- a was hard to make clear.Aaccording to this problem,the paper began with the distribution of its altered belt,on the basis of analyzing mud logging show,to carry out evalua- tion on the electric property,lithology and physical proper- ty of the igneous reservoir.The higher part well area in Z 111 fault block was found to act as the favorable target area for oil and gas development by studying the relationship be- tween igneous invaded zone and oil and gas reservoir in Kong Two interval.The paper put forward the further ex- ploration direction for the area.
