              6日中国石油西南油气田川南深层页岩气攻关传来捷报部署在四川省泸县雷达村的泸203井完成放喷测试关井最高井口压力57.1兆帕测试日产量137.9万立方米成为国内首口单井测试日产量超百万立方米的页岩气井


              泸203井是一口深层页岩气评价井目的是评价泸州区块埋深4000米左右龙马溪组页岩气资源的开发潜力试验深层页岩气水平井优快钻井技术体积压?#21387;?#33402;通过精心组织在地层温度大于140的页岩地层中成功钻成水平段1500米优质储层钻遇率100%井身质量合格率100%借鉴北美新一代压力工艺技术结合川?#31995;?#21306;深层页岩地质工程特征采用“密切割+高强度加砂+暂堵转向”压?#21387;?#33402;成功实现了埋深近4000米破裂压力大于110兆帕水平应力差大于20兆帕微裂缝较发育的页岩储层的体积改造


              近期中国石油足202H1黄202泸203等井相继获得高产气流标志着川南深层页岩气勘探开发技术逐步走向成熟为这一地区86%以上深层页岩气资源的?#34892;?#21160;用奠定了坚实基础进一步坚定了实现川南页岩气中长期发展规划目标的信心
