全球首例古潜山裸眼侧钻分支井技术在中国气田应用
中新社天津5月19日电 (王在御 王君妍)记者19日从中国海油天津分公司得悉，全球首例古潜山裸眼侧钻分支井手艺在中国首个千亿方年夜气田——渤中19-6凝析气田成功利用，标记着中国在深层潜山油气藏开辟方面获得重年夜手艺冲破。 全球首例古潜山裸眼侧钻分支井手艺在中国首个千亿方年夜气田——渤中19-6凝析气田成功利用。(中国海油天津分公司供图) 据悉，该手艺由中国海油天津分公司工程手艺团队研发，合用于深层的新型裸眼空心斜向器侧钻东西可以或许在潜山极硬地层实现安定锚定，钻头在油气井段中如同“火车变轨”，斥地出另外一条分支井眼，有用提高油气藏的表露面积，实现了海上深层深井提高单井产能、下降建井本钱的新冲破。 中国海油天津分公司工程手艺团队环绕“少井高产”方针，靠前摆设、邃密管控、科学施工，在渤中19-6凝析气田M15井中初次成功利用潜山极硬地层裸眼侧钻分支井手艺，是深井开辟的成功实践。 该井主井眼深度5124米，此中古潜山储层裸眼井段487米；分支井眼深度5139米，此中分支裸眼井段429米，储层表露面积翻倍。为定量阐发主支与分支井眼产出进献，该井还利用了中国海油自立研发的高温产剖液面示踪剂监测手艺，实现180℃高温前提下持续60天产出监测，为油藏钻后阐发供给了切确数据撑持。 “潜山极硬地层裸眼空心斜向器分支井手艺的成功实行，可年夜幅增添储层表露面积，优化井网结构，提高单井产能和采油速度，有用下降开辟本钱。”中国海油天津分公司副总司理喻贵平易近介绍。 跟着海上油田的不竭勘察开辟，渤海油田的开辟程序慢慢迈向深层，而深层油气藏首要包含在古潜山的裂痕中，开辟难度年夜、投资本钱高，持久以来一向是全球石油工业面对的攻关困难。此次潜山极硬地层裸眼侧钻分支井手艺的研发利用，对渤海油田产能扶植晋升、保障京津冀地域能源供给具有主要意义。(完) 【编纂:刘阳禾】。
本文心得:
Located in Jiangmen's Xinhui district, the Renyi Market Alley is a vibrant hub that reflects the essence of the local community. As a journalist, I recently had the opportunity to explore this hidden gem and immerse myself in the sights, sounds, and stories that make it truly unique.
Stepping into the Renyi Market Alley is like taking a journey back in time. The narrow streets are lined with shops and houses that have stood the test of time, some dating back several decades. Each building tells a story, sharing the history and heritage of the neighborhood.
As I strolled through the maze-like alleys, I was captivated by the intricate architecture and the glimpse of a bygone era. The traditional courtyard houses, with their red-brick walls and tiled roofs, exuded a sense of nostalgia that is hard to find in modern cities. It was a reminder of the importance of preserving our cultural heritage.
