四川盆地的群山之间坐落着我国最大规模海相整装高含硫气田——普光气田，截至目前，普光气田海相页岩气累产量超6000万立方米，标志着该区块接替产能建设取得阶段性成效。

Among the mountains in the Sichuan Basin lies the largest marine-type complete-gas-field in China - the Puguang Gas Field. As of now, the cumulative output of marine shale gas from the Puguang Gas Field has exceeded 60 million cubic meters, marking the achievement of phased results in the replacement capacity construction of this area.

从首口井到规模开发：稳步扩大产能版图

From the first well to large-scale development: Gradually expanding the production capacity territory

海相页岩气，是指海相沉积环境形成的富有机质页岩中生成并储集的天然气，也是当前我国页岩气勘探开发的主力类型。对普光气田而言，它不仅是接替传统含硫气产能的有力补充，更是推动气田长效稳产的优质后备资源。

Marine shale gas refers to the natural gas generated and stored in the organic-rich shale formed in the marine sedimentary environment. It is currently the main type of shale gas exploration and development in China. For the Puguang Gas Field, it not only serves as a powerful supplement to the capacity of traditional sulfur-containing gas, but also represents a high-quality backup resource for promoting the long-term stable production of the gas field.

2023年5月，普光气田海相页岩气的“第一口井”——雷页1井正式投产，拉开了海相页岩气勘探开发的序幕。此后，普光气田将目标锁定在二叠系大隆组这一主力开发层位，持续推进规模建设。

In May 2023, the "first well" of marine shale gas in Pujiang Gas Field - Leiyi Well 1 was officially put into operation, marking the beginning of marine shale gas exploration and development. Since then, Pujiang Gas Field has focused its efforts on the major development layer, the Dalong Formation of the Permian System, and has been continuously advancing large-scale construction.

截至目前，该区块内已建成3座站场、6口生产气井，日均产气超过18万立方米，持续释放稳产效能。

As of now, three stations and six production gas wells have been built in this area. The daily gas output exceeds 180,000 cubic meters, continuously demonstrating stable production capabilities.

攻坚克难：新井跑出建设加速度

Overcoming challenges: Shinji achieves a significant acceleration in construction progress

为进一步激活页岩气产能潜力，2025年以来，普光气田加速推进新井钻探建设，高效完成多口井施工任务。

In order to further unleash the production capacity potential of shale gas, since 2025, the Pujiang Gas Field has accelerated the construction of new wells and successfully completed the construction tasks of multiple wells.

今年以来，面对工期紧、乡村村道维修等不利因素，开发建设团队迎难而上，连续40多天驻守现场、盯紧关键节点，高效完成雷页1井组产施工任务。雷页1-1HF井、雷页1-2HF井、雷页1-3HF井等3口海相页岩气井陆续投入生产，助力海相页岩气产量再上一个台阶。

Since the beginning of this year, in the face of tight construction schedules and difficulties such as rural village road maintenance, the development and construction team has risen to the challenge and has been stationed at the site for over 40 consecutive days, closely monitoring key nodes. They have efficiently completed the production construction tasks for the Leiye 1 well group. The Leiye 1-1HF well, Leiye 1-2HF well, and Leiye 1-3HF well, among others, three marine shale gas wells, have been put into production, helping to further increase the output of marine shale gas.

技术攻关：老井稳产打出组合拳

Technical breakthrough: A comprehensive strategy for maintaining stable production in old wells

在扩大增量的同时，技术团队同步发力老井稳产攻关。针对老井积液、井筒状况变差等影响页岩气连续稳定生产的问题，技术团队系统梳理了页岩气藏在自喷排液、间歇排液、连续排液等不同阶段的排采特征，逐一开展技术攻关。

While expanding the production volume, the technical team is also working simultaneously on the task of maintaining stable production in old wells. In response to issues such as liquid accumulation in old wells and deteriorating wellbore conditions that affect the continuous and stable production of shale gas, the technical team systematically analyzed the production characteristics of shale gas reservoirs at different stages (such as self-flowing liquid discharge, intermittent liquid discharge, and continuous liquid discharge), and carried out technical research on each stage.

经过反复摸索，团队成功形成了“放喷排液+泡沫排液+气举排液+增压开采”一体化积液处理对策，结合测试资料进行现场跟踪，验证措施效果，建立了“一井一策”管理体系和井筒状况对策预测图版，有力指导现场连油通井、定期洗井、放喷排液等措施制定和实施，排采效果明显提升。

After repeated trials and errors, the team successfully developed an integrated liquid discharge treatment strategy of "release and discharge + foam discharge + gas lift discharge + pressure boosting production". They combined the test data for on-site tracking to verify the effectiveness of the measures, established a "one-well-one-strategy" management system and a wellbore condition countermeasure prediction chart, which effectively guided the formulation and implementation of measures such as continuous oil well tripping, regular well flushing, and release and discharge of fluids, and significantly improved the production and recovery efficiency.

下一步，普光气田将持续优化钻采输一体化机制，完善开采技术，夯实产能根基，稳步扩大页岩气开发规模，持续提升清洁能源保供能力，全力推动普光气田高质量发展。

Next, the Puguang Gas Field will continue to optimize the integrated mechanism of drilling, production and transportation, improve the extraction technology, consolidate the production capacity foundation, steadily expand the scale of shale gas development, continuously enhance the capacity for providing clean energy, and fully promote the high-quality development of the Puguang Gas Field.
