Abstract

The authors show that data on characteristics of drill mud penetration zone improve reliability of geoinformation obtained from borehole geology and geophysics. The developed procedure for the data interpretation takes into account the geomechanics and hydrodynamics of drilling. A part of the drill mud penetration zone is represented by mudcake which prevents direct measurement of porosity and permeability. The article describes the experimental studies on growth of the mudcake on the samples of low-permeable sandstone from the Jurassic reservoir rock mass using an original facility. The petrophysical nonuniformity of the mudcake was determined. The repeated measurements revealed the mudding zone.

低渗透性砂岩样品泥饼形成的实验研究

摘要作者的研究表明，钻孔泥浆穿透区的特征数据提高了从钻孔地质学和地球物理学获得的地质信息的可靠性。所开发的数据解释程序考虑了钻探过程中的地质力学和流体力学。钻井泥浆渗透带的一部分是泥饼，无法直接测量孔隙度和渗透率。文章介绍了利用原始设备对侏罗纪储层岩体低渗透砂岩样本上泥饼生长情况进行的实验研究。确定了泥饼的岩石物理不均匀性。反复测量发现了泥化带。
