摘　　要：MDT是Schlumberger公司推出的新一代模块式动态地层测试器,其显著特点是其灵活的模块式设计,各模块可根据地层测试的需要进行组合.1995年～2003年期间,总共在川进行了26井次MDT测井.利用MDT测井资料所提供的信息,可有效地获取地层压力,准确确定流体性质,计算原状地层渗透率,研究流体流动情况.但由于四川储层多为低孔低渗及裂缝性储层,给MDT测试带来了很多困难.在理论研究与现场应用相结合的基础上,通过对MDT测井技术在四川低孔、低渗储层的适用性研究,总结出MDT的适用条件以减少不必要的浪费,并对如何提高MDT测试成功率做出了分析以及总结MDT测井资料的处理解释方法,以推动MDT这一测井新技术在四川盆地以及陆上油田的更为成功的应用,加速油气勘探周期、降低油气勘探成本.MDT is a modular dynamic formation tester of new generation, developed by Schlumberger Company, its obvious peculiarity is the flexible modular design with each module combinable according to the formation testing necessity. In 1995~2003, there were totally 26 well·times of MDT logging conducted in Sichuan. By using the information provided by MDT logging data, the formation pressure may be effectively acquired, fluid properties exactly determined, original formation permeability calculated, and fluid flowing situation studied. But owing to the reservoirs in Sichuan mostly to be those of low porosity and permeabity, and fractured, this brings many hardships to MDT testing. On the basis of theoretical research combined with on-site application, through the applicability research of MDT logging technique to low porosity and permeability reservoirs in Sichuan, the applicable condition of MDT is summarized to reduce the unnecessary waste, the analysis of how to enhance the success ratio of MDT test raised, and the treatment and interpretation method of MDT logging data summarized so as to promote this MDT new technique to still more successful application in Sichuan Basin and on-land oil fields to accelerate oil and gas exploration period and low oil-gas exploration cost.
