盐膏层钻井,特别是深井盐膏层和复合盐层钻井,是一个世界级的钻井技术难题。胜科1井在三开沙四段共钻遇3套盐膏层。其中第1、第2套盐膏层对钻井施工带来了很大的困难。讨论了胜科1井在巨厚盐膏层钻井中,在钻井液、工程等方面所采取的相应措施,并为勘探开发胜利油田盐下油气藏积累了丰富的经验。 Salt-and-silt drilling, especially deep well salt and composite salt drilling, is a world-class drilling technology challenge. Shengke 1 well in the three open sand four sections were encountered 3 sets of salt paste layer. Among them, the first and second sets of salt-and-ointment layers bring great difficulties in drilling construction. The corresponding measures taken by Shengke Well 1 in the drilling of thick thick salt layer are discussed in terms of drilling fluid and engineering. It also has accumulated rich experience in exploration and development of the submarine reservoirs in Shengli Oilfield.
