【摘要】：利用电阻率测井理论和反演技术,以三参数(侵入带半径、侵入带电阻率、地层电阻率)反演为重点,在常规双侧向曲线反演技术的基础上,结合电成像测井资料,建立了一种基于电成像测井和双侧向测井的联合反演方法,即利用电成像测井探测深度浅且分辨率高的特性为双侧向反演提供精细的地层界面、产状和侵入带电阻率信息;运用双侧向测井资料进行迭代反演进一步得到侵入带半径和地层电阻率参数。实际测井数据的处理结果表明,本文提出的联合反演方法提高了双侧向反演结果及测井解释的精度,进一步提高了常规测井资料对油气储层的识别能力。
[Abstract]:Based on the theory of resistivity logging and inversion technique, the inversion of three parameters (radius of invasion zone, resistivity of intrusive zone, resistivity of formation) is emphasized. Based on the conventional double lateral curve inversion technique, electrical imaging logging data are combined. A combined inversion method based on electric imaging logging and dual lateral logging is established, which uses the characteristics of low depth and high resolution of electric imaging logging to provide fine formation interface, occurrence and intrusion zone resistivity information for dual lateral inversion. The radius of the invasion zone and the resistivity parameters of the formation are further obtained by iterative inversion using the dual lateral logging data. The processing results of actual logging data show that the combined inversion method proposed in this paper improves the accuracy of dual lateral inversion results and log interpretation, and further improves the recognition ability of conventional logging data to oil and gas reservoirs.
