| 摘 要： | 文章通过对河南中牟区块海陆过渡相太原组和山西组页岩气形成的地质条件与特征分析,认为区块构造较为简单、稳定,其海陆交互相沉积环境控制太原组和山西组页岩发育,分布广泛,富含有机质页岩厚度大,为页岩气目标层;有机碳含量w(TOC)=1.1%~3.7%,有机质类型为Ⅲ型,有机质成熟度指标镜质体反射率(Ro)3.0%~3.8%;目标层有效孔隙度1.0%~5.0%,黏土矿物以伊利石和伊/蒙混层为主;含气量0.5~3.3m~3/t,平均1.7m~3/t。对牟页1井太原组、山西组三段采用快钻桥塞分段压裂,累计注入压裂液量5 055.9m~3,加砂量202.7m~3,三层合采求产为1 256m~3/d,标志着南华北盆地海陆过渡相页岩气勘探取得重大发现。通过地质评价和资源量计算,中牟区块太原组、山西组页岩气地质资源量较为丰富,勘探有利区面积大,具备较好的页岩气勘探前景。
