为了提高大牛地气田油气储藏动用率和单井产能,2002年在大牛地气田首次进行了水平井施工,经过多年水平井提速的探索与研究,大牛地气田水平井在井身结构、钻头选型、钻井液防塌技术和下套管固井防漏等方面逐渐形成了一系列配套成熟的特色技术,通过现场施工表明,这些配套技术在大牛气田提速提效上取得了较好效果,对其它油气田水平井提速提效也具有重要参考价值。
In order to improve oil and gas reservoir utilization rate and single-well productivity in Daniudi gas field, horizontal well construction was first carried out in Daniudi Gas Field in 2002. After years of exploration and research on horizontal well speed increase, horizontal wells in Daniudi Gas Field have been widely used in well structure, Bit selection, drilling fluid anti-collapse technology and under casing leakage prevention and other aspects of the gradual formation of a series of supporting mature features of technology, through on-site construction shows that these supporting technologies in the Taurus gas field to speed up and efficiency achieved better The results also have important reference value for raising speed and efficiency of horizontal wells in other oil and gas fields.
