摘要:
N气田H3c层上部发现了典型的低阻气层,且具有一定的储量规模。该低阻气层的电阻率接近水层的电阻率,且低阻成因认识不清,给测井解释模型的选择和饱和度准确计算带来了较大的难度。针对这些问题,采用微观分析和宏观分析相结合的思路,使用了X-衍射、压汞等岩心分析化验和随钻电阻率、电成像和核磁共振测井等资料,运用和相邻常规气层对比的方法,对H3c上部形成低阻气层的原因进行了分析,认为造成低阻的原因为高不动水饱和度和粘土附加导电作用,并在此基础上选用了可以定量体现出粘土附加导电作用的W-S饱和度模型对低阻气层进行测井评价,取得了良好的效果。
Abstract:
Typical low-resistivity gas layers were found in the upper H3c layer of N Gasfield, which has a considerable reserve scale. The resistivities of these layers are very close to those of aqueous layer. In addition, the forming reason is confused. As a result, it is very hard to choose a suitable logging interpretation model and calculate the saturation of gas layer. In order to solve these problems, based on the thinking of combining microcosmic analysis with macrocosmic analysis, with the use of core analysis such as X-ray diffraction, mercury injection, and so on, and logging data just like LWD resistivity, imaging and magnetic resonance, the forming reason of low-resistivity gas layers in the top of H3c was analyzed by comparing with adjacent conventional gas layers. It is considered that the low resistivity is caused by high irreducible water saturation and the additional conductivity of clay. On the basis of above analyses, the W-S saturation interpretation model, which can reflect the additional conductivity of clay quantitatively, was used to evaluate the low-resistivity gas layer. So a good effect was acquired.
