英文摘要	核磁共振测井是一种适用于裸眼井的测井新技术,是目前唯一可以直接测量任意岩性储集层自由流体(油、气、水)渗流体积特性的测井方法.核磁共振测井与其他测井方法在孔隙度解释中的不同之处就是核磁共振测井能解释束缚流体和可动流体孔隙度.采用新一代的核磁共振测井仪测井,还能解释出粘土束缚流体孔隙度,具有明显的优越性.目前,对含有商业价值油气产量的低电阻率地层的识别越来越重要.涩北气田作为第四系疏松砂岩气田,由于泥质含量和地层水矿化度高等因素存在大量的低阻气层,所以用电阻率曲线很难将这类低阻气层与水层和干层区分开来.通过核磁共振测井在SX井的应用情况,阐明用核磁共振测井分析、评价疏松砂岩储层孔隙结构及流体性质的实际应用效果.; The NML logging as one of the new borehole logging technologies,is a present sole logging tool to measure infiltrating volume of free fluid(i.e.oil,gas,water)in lithologic reservoir.Compared with other logging method,the NML logging has a ablity to explain the bound fluid and dynamic fluid porosity in the interpretation of porosity.The new generation of NML logging instrument is also used to explain clay-bound fluid porosity.It is increasingly advantage to identify the low-resistivity layer in commercial oil and gas pool.There are a large number of low resistance gas layers due to high clay content and formation water salinity in Sebei gas pool as Quaternary unconsolidated sandstone pool,it is difficult by resistivity curves to distinguish low-resistivity layer with water layer or dry layer.The successful case that the NML logging was used in well SX indicate that the NML logging is valid in analyzing and evaluating pore structure of unconsolidated sandstone and nature of fluid.; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 2; 310-315; 21
