Abstract

The lower Indus basin is leading hydrocarbon carriage sedimentary basin in Pakistan. Evaluation of two sorts out wells namely Sawan-2 and Sawan-3 has been assumed in this work for estimation and dispensation of petro physical framework using well log data. The systematic formation assessment by using petro physical studies and neutron density cross plots reveal that lithofacies mainly composed of sandstone. The hydrocarbon capability of the formation zone have been mark through several isometric maps such as water saturation, picket plots, cross plots, log analysis Phie vs depth and composite log analysis. The estimated petro physical properties shows that reservoir have volume of shale 6.1% and 14.0%, total porosity is observed between 14.6% and 18.2%, effective porosity ranges 12.5-16.5%, water saturation exhibits between 14.05% and 31.58%, hydrocarbon saturation ranges 68.42% -86.9%, The lithology of lower goru formation is dominated by very fine to fine and silty sandstone. The study method can be use within the vicinity of central Indus basin and similar basin elsewhere in the globe to quantify petro physical properties of oil and gas wells and comprehend the reservoir potential.

利用测井资料对沙湾2、沙湾3气田进行参数估算

印度河下游盆地是巴基斯坦主要的油气运输沉积盆地。本文以沙湾2井和沙湾3井为研究对象，利用测井资料对沙湾2井和沙湾3井的油气物性框架进行了评价。通过岩石物理研究和中子密度交叉图对储层进行了系统评价，发现岩相以砂岩为主。通过含水饱和度、尖桩图、交叉图、测井分析和复合测井分析等等距图，对储层的含油气能力进行了标注。储层物性分析表明，储层体积为页岩6.1% ~ 14.0%，总孔隙度为14.6% ~ 18.2%，有效孔隙度为12.5 ~ 16.5%，含水饱和度为14.05% ~ 31.58%，含油饱和度为68.42% ~ 86.9%，下古鲁组岩性以极细~细砂质砂岩为主。该研究方法可用于印度河中部盆地附近以及全球其他类似盆地，以量化油气井的石油物理性质，并了解储层潜力。
