摘要

为了有效地识别和精确地评价以低孔低渗、微裂缝发育为特征的气层,用岩心资料刻度测井资料,在地质条件约束下,以细分层的“四性”关系研究为基础,提出了用直接识别、交会图、数学、综合分析等方法定性识别气层;在对裂缝深入研究的基础上,提出了气层的精细解释模型。该气层测井评价方案的投入应用,提高了测井对气层的识别能力和定量评价精度,从而为长庆气田的深入勘探与进一步开发提供了科学依据。

Abstract

In order to effectively identify and accurately evaluate

the gas - layer whose characters are low - porosity , low -

permeability and grown micro - crack. On the base of four -

characteristic relations’research , well - logging data are

scaled by core data ,then direct - identification ,cross - plot ,

mathematics and comprehensive analyzing methods are put

forward to idvntify gas - layers qualitatively in the restriction

of geological conditions ;On the base of cracks’s identification

and the precision of gas - layers’s identification and the

precision of gas - layers’evaluation in well - logging are

improved ,therefore science warrant is broughe forward to the

thorough exploration and farther exploitation in Changqing

oilfield.
