英文摘要	印支期—燕山早期的挤压逆冲使潜山构造抬升，石炭系—二叠系遭受剥失后，奥陶系长期遭受风化淋滤。由挤压逆冲形成的高角度裂缝和风化淋滤形成的粒间孔、溶蚀孔洞组成潜山储层的主要储集空间。钻井岩样由于地层静压力的降低而导致总体积发生膨胀。岩石骨架的压缩系数小，围压的释放主要导致岩石孔、缝隙空间的扩大，因此，在测算地下原始孔、缝隙度时应考虑地层静压力。我们测得的奥陶系潜山储层的综合空隙度为4.7％。以空隙度为主要评价指标，划分出四级储层，其中Ⅰ、Ⅱ级储层是本区储产能力最强的储层，能够获得稳定的高产油气。; In the Indosinian and early Yanshanian orogenies, the buried hill structure rose because of compression and thrusting. After the Carboniferous and Permian had been peeled, the Ordovician was weathered and leached for a long time. The compressed and thrust high-angle crevice, the weathered and leached interparticle aperture and solution cave are the main space for the reservoir. With the abasing of the stratum static load, the bulk of the core sample come into expansion. Because the compressibility factor of the rock skeleton is small, the interstitical pore space is larger. Therefore, the measure pressure of original porosity and interstitical ratio on the surface must be equal to downhole pressure. The static pressure of the reservoir bed is 45 MPa. Finally, the measured comprehensive voidage is 4.7%. They are divided into 4 level reservoir beds. Among them the Ⅰ and Ⅱ level beds are the strongest reservoirs for oil-gas storage and production in the region. They can obtain smooth high-capacity oil and gas.; 湖南省中青年科技基金; 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 0; 1; 102-108; 25
