| 中文摘要:为了提高大庆地区深层钻井速度，保护和发现储层，依据Mohr-Coulomb准则，引进非线性校正系数，建立了大庆地区深井地层坍塌压力预测模型，并从地质条件、气源井条件、安全性、经济性以及技术条件等几方面分析了徐深气田进行天然气钻井的可行性。优选徐东、徐中、丰乐、升平区块的泉二段至营城组中部（2700～4000 m）为天然气钻井井段。研究结果表明，应用天然气钻井来提高大庆地区深层的钻井速度是完全可行的，并有利于提高深层天然气勘探发现效率。 |

| Abstract:In order to improve deep drilling speed, protect and detect reservoir of Daqing, based on Mohr-Coulomb criterion and by the introduction of linear correction coefficient, the model of formation caving prediction for deep well was established. The feasibility analysis is made on the natural gas drilling in Xushen gas field about geological conditions, gas well conditions, safety, economy and technical conditions. The second section of Quantou formation to central Yingcheng formation（about 2700~4000m）of Xudong, Xuzhong, Fengle and Shengping blocks are determined by optimization as natural gas drilling sections. The results show that it is feasible to improve deep drilling speed by natural gas drilling, which is also beneficial to deep natural gas exploration in Daqing. |
