其中,种子千粒重变异最大;旗叶长度、花序形状次之;穗叶距、花药宽度、旗叶宽度等性状变异中等;而花序长度、株型、叶宽、种子长度变异最小。2鸭茅植物形态学特征间存在明显相关性,花序直立、紧缩的鸭茅,叶片窄长,茎秆粗壮,旗叶较长,雄性生殖器官发育良好,结种性能强;而花序下垂、开展的鸭茅则与之相反。3聚类分析表明,不同野生鸭茅种源可划分为3类,其中花序下垂种源聚于一类;而花序直立的种源分居另两类。4从形态学特征及相关农艺性状分析,花序直立的鸭茅更具开发利用潜力。

The reservoir rock types in the region of interest are grain limestone, algal limestone, cryptite, siltstone, muddy limestone and mudstone. The thesis identified as a result of changes in the deposition causing the heterogeneity in plane, and then the geological oil reserves have been calculated in accordance with the areal heterogeneity.3、Based on the data of core analysis, bore logging, array induction imaging log and FMI, porosity and permeability model were built using regression analysis. Through testing 45 rock samples, a, b, m, n value were obtained and used to calculate single-layer oil saturation value using the Archie formula. According to the theory of laterolog and inductolog, resistivity ratio and cross plot were used to identification effective thickness. Effective thickness was identified delicately in 103 wells. Based on the over work, active porosity and oil saturation was calculated accurately.4、According to observation of 100 pieces of the thin slices, cast thin slices and 383m core in three wells, the chief diagenesis in this area were compaction, cementation, denudation and cataclasis. Cementation and denudation were universally influenced active porosity this area. The intergranular pores, residual pores and secondary pores were formed in thin carbonated reservoir of lacustrine facies.5、The influence of reservoir heterogeneity to reservoir calculation was analyzed systematically using actual data. And the conclusions were as follows:①The principal reason leading to oil distribution unequal is interior structural feature of reservoir in structural hydrocarbon reservoir.
