江汉油田页岩气排水采气技术达到国际先进水平

日期: 2019-07-07
浏览次数: 0

截至5月底,涪陵页岩气田现场共实施各类排水采气工艺181井次,工艺成功率97.6%,累计增产页岩气共计7.5亿方。页岩气排水采气技术为国内首创,中国石化江汉油田拥有多项自主知识产权,整体技术达到国际先进水平。

    页岩气井存在的挑战和难题在于对不同气井在不同生产阶段的生产规律认识和相适宜的采气技术优化研究。排采项目组长江汉油田高级专家陈建达说,随着气藏进入产量递减阶段,携液采气能力减弱,消除气井积液成了急需解决的难题。

    针对当前页岩气开采的实际情况,江汉油田成立页岩气排采工艺研究专项课题组,开展系统的排水采气技术攻关,不断优化推广工艺技术。该油田技术人员应用大数据分析,建立页岩气井采气基础理论模型以及页岩气井采气工艺优化评价方法,明确了涪陵页岩气田全生命周期开采对策,优选了适应于页岩气井的优选管柱、柱塞气举、泡排、增压开采等排采工艺系列,其中页岩气井智能柱塞排采技术,攻克了常规柱塞技术无法在页岩气井应用的技术瓶颈,并创新形成了以常规弹块式组合柱塞、轻量化组合柱塞、可卸载组合柱塞为主的页岩气井智能柱塞系列。目前涪陵气田已应用智能柱塞排采技术的页岩气井,日均产水量由7.4方提高到13.1方,平均生产时率提高11%,日均产气量提高达70%。

    通过三年来的持续攻关,江汉油田在页岩气排采研究领域先后取得30余项国家专利,多项成果经总部鉴定达国际领先水平,新技术成功应用100余井次,累计增产页岩气达7.5亿方,为涪陵页岩气田高效开发提供了有力支撑。此外,该油田主导编制的多项行业标准、企业标准已被推广应用,江汉油田在页岩气排采研究的领先优势已经得到行业内的广泛认可。

凤达小课堂开课了,夏天用电安全早知道!  01不要用潮湿的手去触碰电源 夏季为高温、雨水较多的季节,人容易出汗,出汗时触电的可能性和严重性均超过平常。出汗的手与干燥的手的电阻是不一样的,同样条件下,人出汗时触电的可能性和严重性均超过一般,而且夏季衣服单薄,部分皮肤裸露在外,与其他季节相比易直接接触带电体,所以应格外注意不要用手去移动正在运行的电器。 02不使用的电器及时切断电源 家用电器的绝缘保护时间一长,可能就会出现毁损漏电情况,这样一来就容易引起火灾,尤其是一些和水有关联的电器,比如热水器、洗衣机等家用电器,不使用时最好切断电源。 03家中浸水,关闸断电 家中若不慎浸水,应先关闭总闸切断电源,防止正在使用的家用电器因浸水而造成绝缘损坏发生事故,并通知专业人员进行绝缘检查。 04空调使用非小事 夏季天气炎热,只有空调的运转才能给我们一丝凉爽之意,但空调使用绝非小事。夏季空调温度26℃为宜,但是如果以26℃运行时间后调高1℃,可以节省约10%的耗电量,也可防止温度过低造成的关节受凉等空调病。开空调的同时应关好门窗,尽量减少不必要的能耗。 05禁止超负荷用电 夏季经常会发生超负荷用电的情况,要知道严重的超负荷用电会导致电压降低,影响电压质量,造成电线发热加剧,绝缘老化加速,影...
