摘要:
鄂爾多斯盆地東緣臨興-神府區塊是典型的低滲透、低產量、低豐度致密巖性圈閉氣藏,氣藏勘探難度大,主力層位是煤系地層山西、太原、本溪組。以煤系地層致密砂巖儲層地質和測井基礎理論為指導,綜合利用巖心測試、地質和測井等資料,結合電成像測井資料,圍繞臨興-神府地區目標儲層展開測井資料解釋綜合評價。研究區巖性共劃分出礫巖、粗砂巖、中砂巖、細砂巖、粉砂巖、碳質泥巖、泥巖、碳酸鹽巖及煤9種巖性,總結建立7種常見層理構造的成像圖像、傾角矢量及地質模型一體化的綜合識別模式。結合區域背景認為研究區本溪組、太原組為有障壁濱岸沉積環境,主要包括潮汐水道、瀉湖沼澤、混合坪、碳酸鹽巖丘等沉積微相; 山西組為三角洲前緣沉積環境,主要包括水下分流河道、河道間、河口壩3種微相。該研究對于該地區天然氣勘探開發有一定的指導意義。
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.
