摘要:

由于实际测井情况的复杂性,存在部分泥浆侵入井的电阻率曲线只含有随钻电阻率曲线,并且由于该电阻率曲线测量时泥浆还未完全侵入,因此,常规泥浆侵入校正方法不能应用于此类井中的泥浆侵入校正。为此提出一种新的校正方法,即结合泥浆侵入机理和改进体积模型得到侵入前后地层含水饱和度关系式,对RPM(Reservoir Performance Monitor-储层性能监测仪)测量的含水饱和度直接进行校正,来有效规避电阻率测井资料的不适用性。将校正模型运用于实际测井资料解释中,发现解释结论与实际产出情况一致,校正了由随钻电阻率曲线进行泥浆侵入校正的解释结果,由此验证了该校正方法的可行性。该方法为泥浆侵入校正提供了一种全新的思路。

Abstract:

As the actual logging situation is complex, some resistivity curves of mud invasion wells only contain resistivity curve while drilling. And as the mud invasion is not complete during the measurement, conventional mud invasion correction methods can not be applied to the mud invasion correction in this kind of wells. In order to solve this problem, a new correction method is proposed, that is, the water saturation are corrected directly with the relation between water saturation before and after mud invasion according to the improved volume model. The water saturation measured by RPM is corrected directly to effectively avoid the inapplicability of resistivity logging data. Then the correction model is applied to the interpretation of logging data, and it is found that the interpretation conclusion is consistent with the actual outputs. The interpretation results of mud invasion correction by resistivity curves while drilling is corrected, which verifies the feasibility of the correction method. This method provides a new idea for the mud invasion correction.

Key words: while drilling, mud invasion, volume model, water saturation, RPM(Reservoir Performance Monitor)
