涪陵頁巖氣田處于典型的喀斯特地貌區(qū)，地質(zhì)條件復(fù)雜，淺層地層承壓能力低，固井過程中極易發(fā)生井漏，造成固井質(zhì)量不合格，從而影響氣田的產(chǎn)量和壽命，淺層固井防漏一直是制約氣田發(fā)展的技術(shù)瓶頸。為解決此問題，勘探分公司積極與中石化石油工程技術(shù)研究院一起研究討論，通過充分調(diào)查研究，決定在焦頁9井中應(yīng)用泡沫水泥固井技術(shù)。
泡沫水泥固井技術(shù)是中石化工程研究院研究開發(fā)的低密度彈塑性水泥漿體系，該體系具有密度低、彈性可壓縮、滲透率低、隔熱保溫好和相對(duì)較高的抗壓強(qiáng)度等優(yōu)越性能，能較好地解決低壓易漏層、頁巖氣水平井、熱采井等固井存在的技術(shù)難題。目前國內(nèi)仍處于研究階段，應(yīng)用井為數(shù)不多，頁巖氣井更是屈指可數(shù)。
在焦頁9井施工現(xiàn)場，勘探分公司與中石化工程院緊密配合協(xié)作，成立現(xiàn)場施工領(lǐng)導(dǎo)小組，安排固井專家組全程指導(dǎo)施工，不斷優(yōu)化技術(shù)方案，在不同水泥漿注入排量下，分別用不同注氮率、不同施工參數(shù)進(jìn)行匹配優(yōu)化，最終保證了該井的順利施工，固井質(zhì)量優(yōu)質(zhì)。
