摘要

克拉玛依油田中拐地区侏罗系为陡坡沉积体系,具有水力梯度大、相带变化快、厚度变化大的特点。根据中拐地区侏罗系岩相、测井相和地震相标志,以岩心微相标定测井相,以测井相标定地震相。综合研究分析表明,中拐地区下侏罗统三工河组、八道湾组以发育中小型冲积扇、辫状河及辫状河三角洲沉积为主,划分为5个相、16个亚相4、3个微相,并确定了最有利的储集层位及有利相带。
The Jurassic in Zhongguai area in Karamay field is a steep slope sedimentary system with high hydraulic gradient,quick change of facies belt and varied thickness.Based on its lithology,log facies and seismic facies marks in this area in northwestern margin of Junggar basin,the calibrations of log facies from core microfacies and seismic facies from log facies are conducted.The comprehensive study shows that Sangonghe and Badaowan formations of the Lower Jurassic in Zhongguai area is characterized by deposits of medium-small fluvial fans,braided river deltas,and can be classified into 5 facies,16 sub-facies and 43 micro-facies.The most favorable reservoir horizons and facies belts are also determined in this paper.
