摘要
针对南海西部海域莺琼盆地复杂气田勘探实践所遇到的实际问题,开展了非烃类气层测井识别及解释评价方法研究。将三孔隙度气层识别方法发展和完善为四孔隙度气层识别方法,基于烃类气和非烃类气的密度与温压条件关系分析,建立了非烃类气层定量解释评价模型和方法,并在莺琼盆地取得了良好的实际应用效果。
In order to resolve some actual problems encountered in exploration of complex gasfields in Ying-Qiong basin,the western South China Sea,a methodology on logging identification and interpretation of non-hydrocarbon gas zones is researched.A three-porosity method of gas zone identification was developped and improved into a four-porosity method,and based on the relationship between density and temperature and pressure for hydrocarbon and non-hydrocarbon gases,a model and a method were established for quantitative interpretation and evaluation of non-hydrocarbon gas zones.The methodology has resulted in good effects in practical applications in Ying-Qiong basin.
