陕北碳酸盐岩低压气藏测井采集系列的确定

为有效解决中原油田陕北凤险探区下古生界碳酸盐岩地层油气勘探，储层评价中存在的储层划分，裂缝识别，储层流体性质评价的不确定性问题，通过对该区地层地球物理特征及粘土类型的综合分析，认真研究了当前各种测井项目的仪器特点，探测性能，测井环境条件、地层含油气性对测井仪器响应的影响因素及在类似地质条件下的应用效果，从而确定出能满足该探区碳酸盐岩低压气藏储层测井评价的基本测井采集系列及近期能实现的最佳测井采集系列。

The Determination of the Logging Suit for Low Pressure Gas Zone of Carbonate Formation in Shanbei

In order to solve the uncertainty of reservoir zonation,fracture identification and of reservoir fluid evaluation,which existed in exploring and evaluating Palaeozoic carbonate formation group in ShanBei risk acreage of ZhongYuan Oil Field,we have analysed comprehensively the geophysical characteristic and clay type of this regional,and have researched seriously the actors that influence the logging tools response,such as the tools characteristic of various logging suits,investigation ability,environment condition for logging,formation quality,we also have researched the logging application result at the similar formation condition.Thus,we determinate the basis logging suits to meet the logging evaluationg for low pressure gas zone of carbonate formation in this regional as well as the best logging suit in recently.
