摘要:

目前国内外地层压力测井解释方法较多,但大多数方法基于欠压实沉积理论并局限于单一的地层岩性,尤其是针对盆地边缘山前深层构造,单一测井参数确定地层压力误差较大,且无法解释沉积压实机制以外的异常高压。为此,将多种异常高压机制相关的测井参数进行综合解释,建立适合山前复杂构造的地层压力测井多参数计算模型,评价准噶尔盆地南缘高泉背斜高探1井的地层压力剖面,其计算结果与钻井实测数据吻合,相对误差小于3.00%. 同时,基于原始沉积加载—卸载过程力学原理,利用地层压力测井多参数分析判别出高泉背斜深层各层系异常高压的形成机制。

Abstract:

There are many formation pressure testing methods by logging at home and abroad, but most of them are based on the undercompaction theory and limited to a single lithology of formations. Especially for the deep piedmont structures in the margin of the basin, logging interpretation with a single parameter will lead to large errors in formation pressure determination, and cannot give an explanation about more abnormal pressure mechanisms other than sedimentary compaction mechanism. Therefore, the logging parameters related to various abnormal high pressure mechanisms are comprehensively interpreted, a multi-parameter model and several testing methods suitable for complex piedmont structures are established for formation pressure testing by logging and the formation pressure profiles of Well Gaotan-1 in Gaoquan anticline in the southern margin of Junggar basin are evaluated in detail. The calculated results are in good agreement with the measured data and the relative error is less than 3.00%. Meanwhile, based on the mechanical relationship of the original sedimentary loading-unloading processes, the forming mechanism of the abnormal high pressure in the deep strata of Gaoquan anticline is determined by using this multiple logging parameter analysis method.

Key words: Junggar basin, Gaoquan anticline, piedmont structure, logging interpretation, formation pressure, abnormal high pressure
