摘要:
为了精细描述碳酸盐岩储层展布，对滩相沉积刻画的精度要求日益增高。针对川东地区茅口组地层因抬升遭受剥蚀，难以统计颗粒滩真实厚度的问题，提出结合滩地比技术刻画碳酸盐岩滩相类型及分布范围，进而开展碳酸盐岩沉积相描述。利用丰富的钻井资料，通过滩相识别标志建立、连井沉积对比、滩地比统计以及沉积相平面展布等一系列研究，揭示川东地区茅二a亚段从南西到北东沉积相带展布依次为开阔台地－台地边缘－斜坡－盆地，其中台地边缘在邻水县－丰都县－忠县一带近似呈东西条带状展布；台内低能滩和斜坡低能滩主要分布在滩地比0.3~0.5的区域，台内高能滩在滩地比0.5~0.6的区域发育，台缘滩主要分布在滩地比0.6~0.8的区域，钻井试气结果表明滩相沉积对油气产能具有一定的控制作用，且台缘滩比台内高能滩更具有勘探潜力。本次研究表明在碳酸盐岩地层被剥蚀地区，相比滩体厚度，利用滩地比能够更准确的分析颗粒滩的类型及展布范围，从而判断研究层段颗粒滩发育情况。
Abstract:The accurate description of the distribution of carbonate reservoirs requires increasing precision for the characterization of beach facies sedimentation. In view of the difficulty in calculating the real thicknesses of granular beaches on Maokou formation in eastern Sichuan due to uplift and erosion of strata, we characterized the types and distribution range of carbonate beaches based on the ratios of shoal thicknesses to the whole stratum thickness, and then described the carbonate sedimentary facies. Based on abundant drilling data, we conducted a case study by the establishment of identification marks of beach facies, the correlation of inter-well sedimentation, ratios of shoal thickness to stratum thickness and the planar distribution of sedimentary facies. This study indicates that the distribution of sedimentary facies in layer a of Mao2 submember from southwest to northeast in eastern Sichuan is respectively open platform, platform margin, slope and basin, among which the platform margin is approximately east-west banded in the area of Linshui-Fengdu-Zhongxian. The low-energy beaches both in the platform and in the slope are mainly distributed in the area with ratios of shoal thickness to stratum thickness of 0.3-0.5; the high-energy beach in the platform is developed in the area with ratios of 0.5-0.6; and the marginal platform beach is mainly distributed in the area with ratios of 0.6-0.8. The results of well gas test show that beach facies have a certain controlling effect on oil-gas productivity, and the marginal platform beach has more exploration potential than the high-energy beach in the platform. The study shows that in the area where carbonate strata are eroded, compared with the thickness of beach, the use of the ratios of shoal thickness to the whole stratum to accurately analyze the type and distribution range of granular beach so as to judge the development of granular beaches in the layer section.
