高压油气井在下套管完井之后，有时需要射孔向管外高压挤水泥，以补救固井质量问题。对高压油气井来说，这是一项比较难的工艺。近几年来，我们在研究国内外挤水泥工艺的基础上，结合中原油田深层高压油气井的特点，对如何补救深层高压油气井封固质量问题做了一些探讨，形成了一套较为系统的深层高压油气井挤水泥工艺技术。成功地对文１３ —３５７ 井、新文１９５ 井、文７２ —４１７ 井进行了９ 次挤水泥作业，收到良好的效果。
High-pressure oil and gas wells in the next casing after completion, and sometimes need to shoot high pressure outside the tube squeeze cement to cementing quality problems. For high pressure wells, this is a more difficult process. In recent years, on the basis of studying crowded cementing technology at home and abroad, combining with the characteristics of deep high pressure oil and gas wells in Zhongyuan Oilfield, we made some discussions on how to remedy the sealing quality problems of deep high pressure oil and gas wells, and formed a set of more systematic deep High pressure oil and gas well cementing technology. We successfully carried out nine squeeze-cementing operations on Wells 13 -357 well, Xinwen 195 well and Wen-72 -417 well and received good results.
