走近重庆涪陵 探秘页岩气开发背后的国产化奇迹

2017-05-05 08:16:16   央视网

和美国比起来,重庆涪陵页岩气储藏一般埋藏更深,对压裂设备要求高。为实现页岩气高质高效开发,中国石化曾先后引入海德瑞、贝克休斯、斯伦贝谢、威德福等国际知名企业参与开发,让国内外技术设备打擂竞争。

在这种背景下,江汉油田四机厂在2013年成功研制出3000型压裂车,拥有完全自主知识产权,设备最大输出功率3000马力,最高工作压力140兆帕,是目前国际上最大型号的车载压裂装备。整体技术达到世界领先水平,比其他压裂车工作效率高出20%以上,易损件寿命提高20%以上。

国产连续油管作业机后来居上

连续油管作业机又被称为“万能作业机”,细长的油管可在不用压井的情况下,钻进数千米的地层,灵巧地进行钻磨桥塞、下放桥塞、射孔、打捞工具、酸压、冲刷解堵等井下复杂作业。

涪陵页岩气田开发之初,运用的是国外知名公司的连续油管技术,施工成本高,被这些技术服务公司“卡脖子”要钱的事时有发生。为打破该技术的垄断,在经过大量前期试验与研发的基础上,中国石化决定采用国产连续油管作业机。

他们在连续油管车的原有基础上,加装了视频监视系统,使施工过程实现“现场直播”;为注入头加装计数系统,使起下油管的数据更准确;加装操作室报警系统,大幅增加设备操作的安全性……

“井工厂”模式创造“涪陵速度”

2014年3月,由中国石化江汉油田涪陵页岩气公司组织,在涪陵国家级页岩气示范区首次试验“井工厂”模式的焦页30号平台,成功完成了钻机的第一次整体平移。

这次备受注目的平移仅用57分钟,比常规搬安方式节省了约6天时间,并在当天新井完成了开钻,创造了涪陵页岩气工区当天搬迁、当天整改、当天开钻的“三个当天”纪录,展示了“井工厂”开发模式的搬安优势。

同年8月底,在涪陵页岩气田焦页42号平台,国内页岩气开发最大规模的“井工厂”4口井同步交叉压裂施工取得圆满成功。

从逐口井作业模式,转为平台批量化流水线模块作业模式,带来的是流程再造的挑战。一年之后,涪陵页岩气田“井工厂”施工平台达80%以上,施工纪录不断被改写,创造了令人惊叹的“涪陵速度”。

攻克油基岩屑处理难题 创新环保标准

处理后的固废可以与土壤混合种植榨菜

我国页岩气开采因为地质构造等原因,必须用密度较高的油基钻井液撑起岩层,但废弃的油基泥浆和含油的岩屑如何无害化处理,一直是个重大环保难题。

目前涪陵页岩气田开采使用的油基钻井液,均为中国石化自主研发,其成分、配方与国外产品不同,无法复制国外油基岩屑的处理经验。

中国石化江汉油田涪陵页岩气公司还联合有关单位,最终攻克了这个世界性难题,成功实现油基岩屑处理收集“不落地”、存储防渗透、处置无害化、排放高标准。该技术还实现了油基岩屑中废油的循环利用,可从岩屑中提取12%左右的柴油,再次配置到油基钻井液中。同时,处理后的岩屑含油量低于国家0.3%的标准,可以制成水泥、砖头等建筑材料。
