摘要:
柴达木盆地中东部勘探面积大,勘探程度低,潜力大,在钻井过程中新近系虽有不同程度的天然气显示,但却一直未有重大的勘探突破。在对新近系烃源岩的有机质丰度、类型、成熟度等指标分析的基础上,对深层天然气成藏条件及勘探潜力进行了研究。认为一里坪—三湖地区新近系有机质类型以Ⅱ2型和Ⅲ型为主,纵向上,上油砂山组和下油砂山组的暗色泥岩厚度最大;烃源岩在埋深2 800 m进入生气门限,从4 000 m开始生成大量的热成因气,具有一定资源基础。新近系主要为湖泊及三角洲沉积相类型,发育滨浅湖滩砂坝、三角洲前缘砂坝和河道砂等,物性主要受沉积微相、粒度和埋藏深度等控制,鸭湖—涩北、碱石山—船形丘及碱山—红三旱地区是天然气潜在勘探领域。
Abstract:
Yiliping-Sanhu area in Qaidam basin has no major exploration breakthrough for its Neogene strata that have been dilled up to now just have some shows of natural gas. In this paper, the core lab tests of the aboundance, kerogen type and maturity indexes of the organic matter from the Neogene source rocks were presented, by which the deep gas accumulation condition and exploration potential were analyzed. It is recognized that the type of organic matter of the Neogene is dominated by Type Ⅱ2 and Type Ⅲ, and the N22 and N12 have maximum thickness of dark mudstone in vertical in this area; the source rocks get into gas threshold at depth of 2 800 m and generate abundant thermogenic gas starting with 4 000 m, showing that this area has a certain amount of gas resource. In sedimentary facies, the Neogene appears lake and delta developed with shore shallow lake sand bank, delta front sand bank and channel sand, etc., so the physical properties are mainly controlled by sedimentary microfacies, particle size and buried depth. The potential deep gas exploration domain or targets could be in Tahu-Sebei, Jianshishan-Chuanxingqiu and Jianshan-Hongsanhan areas
