中国石油网消息：4月15日，记者从塔里木油田获悉，该油田克拉2-5井累计生产天然气100.1亿立方米，成为克拉2气田第7口累产天然气超百亿立方米的高产气井。该气井与之前的6口百亿立方米气井形成百亿立方米高产气井群，使克拉2气田保持着我国单个气田平均单井产量最高纪录，进一步夯实“西气东输第一源”的重要战略地位。

China Oil News: On April 15th, reporters from Tarim Oilfield learned that the Kalar 2-5 well of this oilfield has cumulatively produced 10.01 billion cubic meters of natural gas, becoming the 7th high-yielding gas well in the Kalar 2 gas field that has produced over 10 billion cubic meters of gas. This well, together with the previous 6 wells that have produced over 10 billion cubic meters of gas, forms a high-yielding gas well cluster of over 10 billion cubic meters. This has enabled the Kalar 2 gas field to maintain the highest average single-well production record among all gas fields in China, further consolidating its important strategic position as the "First Source of West-to-East Gas Transmission".

克拉2-5井所在的克拉2气田，位于塔里木盆地北缘的天山南麓库车坳陷。这里沟壑纵横、地势险峻，地下存在着超高压、超高温等地质开发难题。在这样的“勘探禁区”，塔里木石油人历经多年勘探攻关，于1998年在克拉2井斩获高产天然气流，发现了我国当时最大的特高压、特高产、特高丰度整装气田——克拉2气田，并直接促成了西气东输工程的启动。2004年12月，克拉2气田正式投产，并向西气东输管道供气。

The Kalar 2-5 well is located in the Kalar 2 gas field, which is situated in the southern slope of the Tianshan Mountains at the northern edge of the Tarim Basin. The area is characterized by numerous gullies and rugged terrain, presenting geological development challenges such as ultra-high pressure and ultra-high temperature. In this "exploration forbidden zone", the Tarim oil workers spent many years conducting exploration and research, and in 1998, they discovered a high-yield natural gas flow at the Kalar 2 well, uncovering the largest currently existing fully-arranged gas field with ultra-high pressure, ultra-high production and ultra-high abundance in China - the Kalar 2 gas field. This directly led to the initiation of the West-to-East Gas Transmission Project. In December 2004, the Kalar 2 gas field was officially put into operation and began to supply gas to the West-to-East Gas Transmission Pipeline.

近年来，面对下游日益增长的用气需求，塔里木油田大力攻关有水气藏控水稳产技术，形成见水后主动控产、纵向上产能调整、高渗层强排水、水侵前缘注氮气阻水的“控、调、排、注”核心开发技术，打破了常规强水驱气藏的开发极限，实现克拉2气田全生命周期高质量开发，持续提升天然气生产能力。

In recent years, in response to the increasing gas demand from the downstream market, the Tarim Oilfield has made significant efforts in researching and developing water control and stable production technologies for water-bearing gas reservoirs. They have established core development technologies including active production control upon water encounter, vertical production capacity adjustment, strong drainage in high-permeability layers, and nitrogen injection for water-blocking before water invasion. These technologies have broken the conventional development limits of strong water-driven gas reservoirs and enabled high-quality development of the Kalar 2 gas field throughout its entire lifecycle, continuously enhancing the production capacity of natural gas.

如今，塔里木油田克拉采油气管理区的32名技术和操作人员承担着克拉2气田33口气井的生产运维任务，每名员工管理一口井，单井平均日产量达到86万立方米，创造了“一个人、一口井、一座城”的少人高效开发生产模式。目前，克拉2气田除诞生了7口累产超100亿立方米的气井外，还有12口累产超10亿立方米的高产气井，实现了从高产到长期稳产的跨越式发展。

Nowadays, the 32 technical and operational staff in the Kalarai Oil and Gas Management Area of the Tarim Oilfield are responsible for the production and operation of 33 gas wells in the Kalar 2 gas field. Each employee is in charge of one well, and the average daily output of each well reaches 860,000 cubic meters. This has created a "one person, one well, one city" model of low-staff development and production. Currently, in addition to 7 gas wells that have cumulatively produced over 10 billion cubic meters of gas, the Kalar 2 gas field also has 12 high-yield gas wells that have cumulatively produced over 1 billion cubic meters of gas. This has achieved a leapfrog development from high production to long-term stable production.

随着天然气勘探开发的不断深入，塔里木油田还建成了年最大供气能力达400亿立方米的“西气东输第一站”，开发建设了克深、博孜、大北等19座大中型气田。截至目前，塔里木油田累计生产天然气突破5000亿立方米，连续6年保持年产气量在310亿立方米以上，成为我国三大主力气区之一，为保障国家能源安全、推动能源结构优化和绿色低碳发展发挥着重要作用。

With the continuous deepening of natural gas exploration and development, the Tarim Oilfield has also built the "First Station of the West-to-East Gas Transmission Project", with an annual maximum gas supply capacity of up to 40 billion cubic meters. It has developed 19 medium and large-sized gas fields such as Kecheng, Bozi, and Da Bei. As of now, the Tarim Oilfield has cumulatively produced over 500 billion cubic meters of natural gas, maintaining an annual gas production of over 31 billion cubic meters for six consecutive years. It has become one of the three major main gas regions in China, playing an important role in ensuring national energy security, promoting energy structure optimization and green and low-carbon development.
