一 | 10月18日，中国石化西南石油局在四川盆地部署的金石103HF探井获得高产稳产工业气流，日产天然气25.86万立方米，评价落实地质资源量3878亿立方米。这是我国首次在寒武系筇竹寺组地层取得页岩气勘探的重大突破，开辟了页岩气规模增储新阵地，将为页岩气勘探开发向新区、新层系、新类型领域纵深推进提供有力支撑，助力川渝地区国家天然气（页岩气）千亿立方米级产能基地建设。页岩气是指赋存于富有机质泥页岩及其夹层中，以吸附或游离状态存在的非常规天然气，成分以甲烷为主，主要用于居民燃气、城市供热和发电等。据介绍，四川盆地主要有龙马溪组、寒武系筇竹寺组两套主力海相页岩层系，其中龙马溪组已实现规模开发，包括我国首个深层页岩气田——威荣页岩气田。

三 | Moscow, Oct 9 (UNI) Russian President Vladimir Putin signed a decree to strengthen measures for protecting transport crossing through the Kerch Strait, the power grid connecting Crimea and the main gas pipeline to the peninsula.

Putin on Saturday authorized the Russian Federal Security Service to organize and coordinate measures to effectively protect these facilities, said the decree published by the Kremlin.

Earlier on Saturday, a deadly blast hit the 19-km Crimean Bridge, which consists of two parallel routes for automobiles and trains over the Kerch Strait.

A truck exploded on the road bridge, causing seven fuel tanks of a train heading to the Crimean Peninsula to catch fire. Three people were killed in the blast, which also led to the partial collapse of two spans of the road bridge.

Traffic has reopened to cars and buses with a full inspection procedure needed, while trucks are still required to cross the Kerch Strait by ferry, Crimea's head Sergei Aksyonov said.

Meanwhile, the railway service on the bridge has been fully restored and all scheduled trains, both for passengers and freight, will be able to cross the viaduct, Russian Deputy Prime Minister Marat Khusnullin said on late Saturday.

UNI/XINHUA PRT。图自中国石化，下同中国石化西南石油局加强研究，建立了针对寒武系页岩层系新的评价标准，发现了粉砂质新类型页岩气勘探目的层。同时，面对该层系优质页岩厚度薄、纵向应力差异大、规模改造难度大等问题，攻关粉砂质页岩改造技术，创新采用新的压裂工艺和压裂液体系，多段压裂改造。十年来，中国石化西南石油局大力提升油气勘探开发力度，建成世界首个7000余米超深高含硫生物礁大气田——元坝气田，探明我国首个深层页岩气田——威荣页岩气田等，落实了合兴场须家河、永川龙马溪组、井研筇竹寺组等千亿立方米以上规模增储新阵地。天然气年产量由2012年的28.2亿立方米上升至2021年的80.01亿立方米，累计生产天然气529.5亿立方米，成为中国石化最大的天然气生产企业。
