川西坳陷什邡-德阳-广金地区蓬莱镇组致密储层成岩相表征
|
摘要
利用铸体薄片、扫描电镜、岩心观察等资料,对川西坳陷蓬莱镇组储层成岩相类型进行划分,建立成岩相测井识别标准,研究区蓬莱镇组成岩相展布、不同成岩相物性、成岩相主控因素。结果表明,将研究区储层划分为溶蚀孔隙成岩相、斑状溶蚀孔隙成岩相、致密胶结成岩相和致密压实成岩相四种成岩相类型;选取深浅侧向、自然伽马、声波时差、密度和补偿中子6条测井曲线,建立了四种成岩相的测井识别标准。以MJ102井为例实现成岩相的剖面划分;并以蓬三段三砂组的成岩相平面展布与沉积相图对比研究。揭示成岩相的分布主要受沉积环境控制;且溶蚀孔隙成岩相和斑状溶蚀孔隙成岩相物性最好,主要发育在分流河道微相中。
Based on data of cast-slice,SEM analysis and core analysis data,the types of diagenetic facies of Penglaizhen Formation in western Sichuan Foreland were distinguished,logging cure features of diagenetic facies was discussed,lateral distributions was examined,porosity and permeability,main controlling factors of diagenetic facies. The results demonstrate that the reservoirs can be divided into four types of diagenetic facies,including corroded porosity diagenetic facies,porphyritic corroded porosity diagenetic facies,cemente tight diagenetic facies and compacte tight diagenetic facies. LLS、LLD、CNL、DEN、AC and GR logging cures build logging identification standards of diagenetic facies were used. MJ102 was used as an example in order to study the distribution of diagenetic facies,the sedimentary facies and lateral distribution of diagenetic facies of the third sand group of third Penglaizhen Formation were compared. The results demonstrate that the distribution of diagenetic facies is mainly controlled by sedimentary environment,the best porosity and permeability are developed in corroded porosity diagenetic facies and porphyritic corroded porosity diagenetic facies of channel.
