摘要:
鄂尔多斯盆地东缘临兴-神府区块是典型的低渗透、低产量、低丰度致密岩性圈闭气藏,气藏勘探难度大,主力层位是煤系地层山西、太原、本溪组。以煤系地层致密砂岩储层地质和测井基础理论为指导,综合利用岩心测试、地质和测井等资料,结合电成像测井资料,围绕临兴-神府地区目标储层展开测井资料解释综合评价。研究区岩性共划分出砾岩、粗砂岩、中砂岩、细砂岩、粉砂岩、碳质泥岩、泥岩、碳酸盐岩及煤9种岩性,总结建立7种常见层理构造的成像图像、倾角矢量及地质模型一体化的综合识别模式。结合区域背景认为研究区本溪组、太原组为有障壁滨岸沉积环境,主要包括潮汐水道、泻湖沼泽、混合坪、碳酸盐岩丘等沉积微相; 山西组为三角洲前缘沉积环境,主要包括水下分流河道、河道间、河口坝3种微相。该研究对于该地区天然气勘探开发有一定的指导意义。
Abstract:
The Linxing-Shenfu block on the eastern edge of Ordos is a typical low-permeability, low-yield, low-abundance tight lithologic trap gas reservoir, which is difficult to explore. The main stratum is the coal-bearing strata Shanxi, Taiyuan and Benxi formations. This paper is guided by the basic geological and logging theories of tight sandstone reservoirs in coal-bearing strata, and comprehensively utilizes core testing, geology and logging data, combined with electrical imaging logging data, to conduct logging data interpretation and comprehensive evaluation around the target reservoir in the Linxing-Shenfu area. The study area is divided into night types of lithology including conglomerate, coarse sandstone, medium sandstone, fine sandstone, siltstone, carbonaceous mudstone, mudstone, carbonate rock, and coal. Seven common bedding structures are summarized and established. Integrated recognition mode of imaging image, dip vector and geological model. Based on the regional background, the Benxi formation and Taiyuan formation in the study area are considered as barrier sedimentary environments, mainly including sedimentary microfacies such as tidal channels, lagoon swamps, mixed slabs and carbonate hills. Shanxi formation is the delta front sedimentary environment, including three types of microfacies:underwater diverted river channels, inter-channel channels, and estuary dams. This study has certain guiding significance for natural gas exploration and development in this area.
