Geophysical characteristics of Ordovician carbonate rock were studied using drilling data. Impedance is affected mostly by material properties and reservoirs types, to a negligibly extent by lithology and flow. Compact layers and minor\|fracture reservoirs of Ordovician carbonate rock have characteristics of high density, high velocity and high impedance, and the prediction of minor fractures reservoir is difficult by the general seismic ways. Big fractures and fractured\|vuggy and vuggy and cavity reservoirs of Ordovician carbonate rock have characteristics of minor density and low velocity and low impedance in central Tarim basin, which obviously different from the surrounding rock and produce obvious characteristics in seismic data, so reservoirs can be predicted by applying general seismic data.

根据已钻井资料，对塔中地区上奥陶统良里塔格组岩石地球物理特征进行了研究，结果表明：物性、储层类型对波阻抗影响最大，岩性、流体对波阻抗影响较小；奥陶系碳酸盐岩致密层和小裂缝型储层具有密度大、速度高、波阻抗值大的特点，利用地震常规预测手段较难预测出小裂缝型储层，而塔中地区奥陶系碳酸盐岩大裂缝型、裂缝-孔洞型、孔洞型、洞穴型储层具有密度小、速度低、波阻抗值小的特点，与围岩具有较为明显的差异，在地震上可以产生明显的响应，可利用常规地震资料来预测这种类型储层。

In other words, underground water is an essential water resource, accounting for 41%-83% of the total. Meanwhile, the formation of limestone soil is slower.(2) Guangxi is a typical karst region. A large difference is noticed in vegetation coverage between karst regions and non-karst regions. The average coverage of bush and forest communities is 14.81% and 12.13% in the karst regions, 1.92% and 31.3% in the non-karst regions.(3) The wide distribution of rocky desertification in Guizhou Province indicates the karst environment is strongly affected by carbonate rocks'properties.
