运用石油地质综合方法,结合现代测试技术、测井技术,将宏观与微观相结合、区域资料与单井资料相结合,在对岩石学、粒度、岩心沉积相标志及测井曲线等进行详细研究的基础上,对子北油田涧峪岔油区三叠系长6油层组各小层沉积微相及其分布规律进行了深入研究.长6油层组储层均属于三角洲平原沉积,发育分流河道和分流间湾两种主要的沉积微相.砂体展布受北东-南西走向的分流河道控制,自长6~2至长6~1,主砂体走向及分布位置有一定的继承性.分流河道砂体对本地区油气聚集有重要控制作用.

By means of comprehensive study on petroleum geology, modern test technology,well logging technology, and the combination of macroexamination with microexamination, regional information with well data, through the petrology, grain size, signs of logging, etc, the authors studied micro-sedimentary facies and distribution law for the Chang 6 reservoir of Triassic in Jianyucha region in Zibei oil field. New understanding of sedimentary microfacies is concluded as followed:Chang 6 reservoir belongs to the delta plain distributary channel sedimentary which includes two main types of sedimentary microfacies-distributary channel and distributary bay.The sandbody is controled by distributary channel which alignment is from northeast to southwest, and the main sandbody trend and distribution have a certain succession in profile section. The delta plain distributary channel sedimentary is beneficial to oil-gas gathering.
