低阻油层成因及影响因素研究

Low Resistivity Reservoir Causes and Influencing Factors

随着深入的勘探开发,我国大部分油田都已经进入了高含水期,大多采收率很低,但在实际生产过程中,往往会发现有这样一类储层,通常在电性上表现为低电阻,实际上含水量大但试油产量高,将这种储层叫做低阻油层。本文对低阻油层的成因进行了系统的研究,阐述了其形成的主要影响因素,对于今后低阻油层勘探开发提供了理论依据,并对实现油田的增产具有重要意义。

With further exploration,most of the oil fields have entered the high water stage,Most of recovery is very low,but in the actual production process,often find that there is such a class of reservoirs,usually exhibit low electrical resistance on the high water,but in fact the test oil production is high,we will this reservoir layer is called the low resistivity reservoir so is the guarantee of low resistivity reservoir of old oilfields top priority.Papers from the complex causes of low resistivity reservoir start,drawing on the past for lack of evaluation in the presence of low resistivity reservoir,the system describes the causes of low resistivity reservoir mechanism,at present,low resistivity reservoir has now become a major oilfield phase one of the main reservoir to increase production.
