腰英台地区属松辽盆地南部长岭断陷中部凸起带的哈尔金构造上,是中国石化东北油气分公司增储上产的重点区块之一。采用欠平衡水平井技术开发存在诸多技术难题,通过技术难点分析,钻井技术攻关及实验应用,应用效果良好,随着吉林油田勘探开发的不断深入,欠平衡水平井技术开发松南深层天然气具有良好的应用前景。
The Yaoyingtai area belongs to the Haerjin structure in the central uplift belt of the Changling Fault Depression in the southern part of the Songliao Basin. It is one of the key blocks for increasing production and increasing production of Sinopec Northeast Oil and Gas Branch. With the development of underdeveloped horizontal wells, there are many technical problems in the development of underbalanced horizontal wells. Through technical difficulties analysis, drilling technology research and experimental applications, the application effect is good. With the deepening of exploration and development in Jilin Oilfield, the technology of underbalanced horizontal wells has a good Application prospects.
