| 中文摘要:随着湘西北地区页岩气勘探开发步伐的不断推进，钻井技术作为页岩气勘探开发的龙头地位日益突显，在页岩气探井钻井实施过程中，井控防喷始终是钻井技术安全中的重中之重。湘西北地区页岩气相比常规油气具有低压、低渗、低饱和度的“三低”特征，钻井过程中所采用的井控防喷技术有本质的不同。通过从井控技术的源头出发，建立起页岩气钻井井眼地层压力理论计算模型，提出相应的井控技术工艺措施和装备，结合湘西北页岩气预探井慈页1井井控实例和成熟的常规油气井控技术，制定一套相应的井控技术工艺措施，做到安全、节约、高效的页岩气钻井。 |

| Abstract:Along with the continuous shale gas exploration and development in northwest Hunan, the position of drilling technology becomes more and more important. In the drilling process of shale gas exploration well, the well control and blowout prevention have been the most important part in the safety drilling technology. Comparing with the conventional oil and gas, shale gas of northwest Hunan has “three low levels” characteristics of low pressure, low permeability and low saturation, the used well control and blowout prevention technologies are different from those used in oil and gas exploration in the essence. Starting from the source of well control technology, the theory calculation model of formation pressure near shale gas well is established and the corresponding well control technical measures and equipments are suggested. Based on the example of well control in shale gas prospecting well-CY1 in northwest Hunan and the mature conventional oil and gas well control technology, a set of well control technical measures are formulated to ensure safe, saving and efficient shale gas well drilling. |
