摘　　要：在储层地质特征分析的基础上,根据常规测井、钻井、录井及测试资料对研究区域内岩性及储层识别方法、储层流体判别方法、储层评价标准等方面进行综合研究。建立束缚水饱和度法、体积压缩系数与泊松比交会法、孔隙度重叠法等储层含气性判别技术。把储层划分为3种类型:较低自然伽马、高孔隙度、高电阻率的常规储层;高自然伽马储层;低电阻率储层,包括低电阻率出水、低电阻率不产水。基于储层分类评价,建立了一套马井—什邡地区蓬莱镇组储层评价标准。On the basis of analyzing the basic geologic characters of reservoir, conventional logging data, drilling data, mud logging data and test data are used to study the lithology identification method, reservoir identification method, reservoir fluid property identification and reservoir evaluation standard. A reservoir gas-baering judgement technique is developed which includes irreducible water saturation method, porosity log overlay method, volume compressibility and poisson ratio intersection method. The reservoir could be divided into 3 types① one is characterized by low gamma ray, high porosity and high resistance, ② one is characterized by high gamma ray and ③ the other is characterized by low resistance. On the basis of reservoir classification evaluation, reservoir evaluation criteria are established.
