新沟咀组下段粘土矿物分布特征与储层敏感性

江陵凹陷新沟咀组下段粘土矿物组合与分布受沉积环境影响明显，高岭石仅分布于三角洲平原相带中，粘土矿物以伊利石、高岭石和有序-无序伊蒙混层及少数绿泥石为特征；三角洲前缘相中粘土矿物组合则为伊利石、绿泥石和有序伊蒙混层；前三角洲及湖盆泥岩相中则以伊利石和绿泥石两种粘土矿物为主。储层的敏感性实验结果表明，本区储层具有中等强度速敏、强—特强水敏、强盐敏和强酸敏性。

An SWOT Analysis of Development of CDM Project in Sichuan

An SWOT(strengths,weaknesses,opportunities,threats) analysis of the development of CDM projects in Sichuan Province leads to the conclusion that sufficient water resources in Sichuan Province lay a solid foundation for CDM project development which is guaranteed by legislation and foreign financial and technical support.However,disadvantages like relatively small scale,simplex emission reduction type and uneven regional distribution of CDM projects obstruct the overall scale and balanced development of low carbon economy in Sichuan.The unique risks of CDM projects and the uncertainty of global emission reduction policy after 2012 are threatening the development of low carbon economy in Sichuan.In order to promote low carbon economy by means of CDM projects,we should give priority to advantageous resource projects,study the laws of CDM project operation,strengthen government guidance,and establish independent pricing mechanism and credit hedge mechanism,etc.
