摘要:

珠江口盆地(东部)已有39年的勘探历史, 其储量发现过程既有自身的特性, 又有与其他盆地类似的共性。影响其储量发现的因素有内在因素和外在因素两个方面。内在因素包括盆地类型、油气地质特征和特殊的海域勘探环境。外在因素包括勘探所处阶段、勘探投入和理论技术。从研究区的油气地质特征、勘探历史和现状出发, 考虑影响研究区储量发现的各种因素, 通过模型研究与对比分析, 建立了研究区储量发展趋势模型, 研究结果表明: 在保证充足勘探投入和理论技术不断进步的前提下, 研究区的勘探生命历程分为早期阶段(1977—2032年, 探明速度小于0.7%)、高峰阶段(2033—2081年, 探明速度大于0.7%)和萎缩阶段(2082年以后, 探明速度小于0.7%)。早期阶段结束时, 探明程度约为20%, 高峰阶段结束时, 探明程度约为57%, 储量发现峰值年度为2055年左右, 届时探明程度约37%。目前, 研究区处于早期阶段末期, 年探明储量增长较快。

Abstract:

The exploration has lasted for 39 years in the eastern Pearl River Mouth Basin, where the process of reserves discovery, compared with that of other basins, has characteristic features in some ways and similar features in some other ways. The factors affecting reserves discovery in the area include internal factors and external factors. The internal factors are the type and geological characteristics of the basin, and the unique marine exploration environment. The external factors include exploration stage, exploration investment, and theory and technology. Based on the oil and gas geological features, exploration history and current situation of the study area, considering various factors influencing the reserves discovery in the area, and by studying and comparing prediction models, we establish the reserves development trend model of the area. We believe that, on the premise that there is sufficient investment, and that both theory and technology develop constantly, the exploration life course of the area can be divided into early stage (1977-2032, the speed of ascertaining reserves is less than 0.7%), peak stage (2033-2081, the speed of ascertaining reserves is greater than 0.7%) and atrophy stage (1982-, the speed of ascertaining reserves is less than 0.7%). At the end of the early stage, about 20% of the oil and gas resources will be found; and at the end of the peak stage, the number is 57%. The peak year is around 2055 when the number is 37%. At present, the study area is in the final phase of the early stage, and the annual proven reserves increase rapidly. The paper serves as a reference for accurately grasping main factors influencing reserves discovery in the area.
