塔里木盆地塔河油田发现历程及其意义

塔河油田位于塔里木盆地沙雅隆起阿克库勒凸起南部,是中国石化新星油气分公司"九五"期间发现的大型油气田.在塔河油田勘探评价过程中,勘探家们不断深化油气成藏和聚集规律性的认识,按照"逼近主力烃源岩,以大型古隆起、古斜坡为勘探目标,靠近大型断裂、大型不整合面,寻找大型原生油气藏"的勘探思路,建立并不断完善了油气层储层识别和预测、油气层保护、油气层酸化压裂等勘探方法技术系列.塔河油田是我国第一个超深层非常规海相碳酸盐岩整装大油田.塔河油田的发现,为新疆维吾尔自治区地方经济快速增长作出了重要的贡献,对于尽快实现国家"稳定东部,发展西部"石油工业发展战略具有重要的作用. 

SIGNIFICANCE AND DISCOVERY HISTORY OF TAHE OILFIELD OF THE TARIM BASIN

Tahe oilfield is located in the south part of Arekule arch of Shaya uplift in Tarim Basin, which was discovered in 1990s, During exploration and production of Tahe oilfield, regularity of hydrocarbon accumulation was continuously recognized. Taking the large paleo-slope near main source rocks as the exploration targets and discovering large primary reservoirs closing to large faults and uncomformities are the basic strategy for petroleum exploration in the area. Much technology, such as identification and prediction of accumulation, protection of reservoir, and acidizing and fracturing of oil-bearing formation, was established and developed. Tahe oilfield is first oilfield of superdeep unconventional reservoirs of marine carbonates in China. It contributed a lot for the economic development in Xinjiang and showed important significance for development strategy of petroleum industry.
