章分析了川东地区与固井相关的地质地貌特征及井眼地质条件，介绍了常用的固井工艺技术，提出了川东地区固井所需要重点考虑的防气窜，防漏失，防硫化氢腐蚀及提高固井技术的几个重要难点问题，论述了解决这些问题的基本办法，通过固井实例，证明了这些办法的可行性和可靠性，因而对进一步提高该地区固井质量具有较广泛的实际指导意义。

Well Cementing Techniques in East Sichuan

On the basis of analyzing the geological and geomorphic features relevant to well cementing and borehole geological conditions in East Sichuan and of introducting several commonly-used cementing techniques in the region,some emphatically considered problems as gas channeling prevention,leak resistance and H 2S corrosion protection and several important difficulties of raising cementing quality as well as the fundamental methods of solving and overcoming these problems and difficulties are proposed in the paper.Through cementing practice it is proved that these methods are feasible and reliable,thus having important guiding significance for further raising cementing quality in this region.
