The Consideration on the Quantitative Division of Fan Delta Subfacies

College of Geo-Resources and Information, University of Petroleum,Dongying Shandong 257061

摘要

摘要: 沉积相的定量划分一直是沉积学中一个难以解决的问题。通过水槽实验发现扇三角洲的形成是一个不断向前缘和侧缘前积、向上加积的过程,加积层和前积层分别代表了扇三角洲的平原部分和前缘部分。从剖面上来看,自扇三角洲根部至前端,平原部分的厚度逐渐减薄,而前缘部分的厚度则逐渐增厚。提出以剖面上前积层和加积层厚度相等的点作为扇三角洲平原与前缘亚相的厘定界限,由此可以解决扇三角洲平原与前缘亚相在平面上的定量划分问题。根据陡坡带扇三角洲模拟实验发现,剖面上前积层厚度与加积层厚度相等的点随着扇体的生长而不断变化,但平原部分与扇体延伸长度的比值λ保持不变,只受原始地形坡度α和扇面坡角β的影响。扇面坡角β是一个经验值常数,因此,在勘探过程中,只要通过地层倾角测井求出原始地形坡度α,再根据地震剖面或单井资料统计确定扇体的延伸长度,就可以计算出前缘亚相的分布范围,从而为预测油气勘探的有利相带提供依据。

Abstract: The quantitative division of sedimentary subfacies is a difficult problem of sedimentology. By flume experiment, it is found that during the formation the fan delta prograde forward and accrete upward constantly. The accretion set and foreset represent respectively the fan delta plain and front subfacies. In the section, the thickness of plain becomes thinner from root to former, and the thickness of front becomes thicker. This paper puts forward that the point where the thicknesses of accretion set and foreset are equal can be regarded as the borderline of fan delta plain and front, which resolves the problem of the quantitative division of fan delta subfacies on the plane. Based on simulation experiment of fan delta in steep slope, the points where the thicknesses of accretion set and foreset are equal change with the development of fan delta, but the ratio of the plain length to the whole fan length is unchangeable, which is affected only by the gradient of original forms and fan surface. The gradient of fan surface is an experiental constant. So, in the exploration, after we get the gradients of original forms by dipmeter and the length of fan delta by seismic profile or the statistics of single-well data, we can calculate the distribution of the front, which provide foundations for the prediction of favorable facies in petroleum exploration.
