最小静校正量基准面校正技术在准噶尔盆地LN6井区应用

Application of Datum Correction of Least Static to Wellblock LN6 in Junggar Basin

最小静校正量基准面技术在原理上优于水平基准面一步法校正,实际应用有多大的优势?以准噶尔盆地LN6井区为例,从基本原理、静校正量计算、速度建场,对最小静校正量基准面校正和水平基准面一步法校正进行对比。在构造圈闭目标识别过程中,使用最小静校正量基准面校正技术,构造精度上取得好的成果,提供部署预探井位一口。

The method of datum correction of least static is superior to that of one-step statics correction with horizonal datum in theory.But how many advantages are there in its practical application？This paper takes Wellblock LN6 of Junggar Basin for example to compare the datum correction of least static with the one-step statics correction of horizonal datum in principle,statics calculation,and velocity- field- built.During identifying structural trap,good results have been obtained by using the technology of datum correction of least static.It provided a exploration well for drilling.
