根据前人对沉积背景和沉积环境的研究和实践发现,阿南马克地区有多个煤层,具有直立的植物根系发展成为化石和干裂隙的结构,地震相以及和油气结构开发前分流河口的前节奏发展,开发半深湖浊积岩的泥岩,属于典型的辫状河三角洲沉积体系。依据对岩石、测井和地震微相的研究,如在艾伦组和腾格尔组发现了并将其分为9种沉积微相,其中,在沙滩和分流河口坝微相的大部分石油和天然气富集,其次是薄砂层、浊积岩、水下分流河道、远砂坝微相水下和过度的土地等依次进行排布。
According to previous studies and practices on sedimentary background and sedimentary environment, it has been found that there are several coal layers in the Anammar region with erect plant roots developing into fossil and dry-fissured structures, seismic facies, and pre-rhythm of the distributary estuary prior to the development of the oil and gas structure The development and development of semi-deep turbidite mudstone, belonging to the typical braided river delta sedimentary system. Based on the study of microfacies of rocks, logs and earthquakes, as found in the Allen and Tengger formations, they are divided into nine sedimentary microfacies, of which most of the oil in sand and distributary estuary microfacies And natural gas enrichment, followed by thin sand, turbidite, underwater distributary channel, distal sand bar microfacies underwater and excessive land, etc. arranged in turn.
