基于井间地震资料的储层精细描述方法
|
摘要
本文探讨了基于井间地震资料并综合运用钻井、测井、地质及地面地震等资料进行储层分析的方法。其主要思路是:首先对目标储层进行标定、识别、追踪并解释;利用地震反演技术得到波阻抗剖面,据此估算其他物性参数(如波阻抗、电阻率、自然伽马、孔隙度等);然后综合测井、钻井资料和井区地质资料对储层进行精细研究,建立井间油藏剖面。文中针对中国西部塔里木盆地某油田稠油层埋藏深、原油黏度高、储层物性差、横向非均质性严重且构造复杂等特点,应用本文方法对高分辨率采集的井间地震资料进行了储层分析研究,明确了三叠系克拉马依组(T2k2Ⅱ)油藏储层的连通性及裂缝发育情况,落实了井间储层中断层的准确位置以及储层横向和纵向上的变化。
The paper probed the method of integrative usage of drilling,logging,geologic and seismic data to carry out reservoir analysis based on cross-hole seismic data.The main idea is that first calibration,identification,tracing and interpretation of objective reservoir; using seismic inversion to get wave impedance profile,from which to evaluate other physical parameters (such as wave impedance,resistivity,natural Gamma and porosity); then,the fine research is carried out for reservoir by integrating the logging,drilling and geologic data in the region,building up cross-hole reservoir profile.In accordance with the characters of deep buried depth,high viscous crude oil,poor physical property of reservoir,serious lateral non-homogeneity and complex structure in inspissated pool of the oilfield in Tarim basin of western part of China,the analysis of reservoir is carried out for the high-resolution acquired cross-hole seismic data by application of the method presented by the paper,which clarified the connectivity of reservoir and fracture-developed situation of Triassic Kramay Formation (T2k2 Ⅱ)reservoir,defined accurate position of faults in cross-hole reservoir and the change of reservoir in both lateral and vertical directions.
