〗塔里木盆地和田古隆起区下古生界发育灰岩、白云岩两类储层。灰岩储层类型有灰岩溶蚀孔隙（孔洞）型储层、灰岩岩溶缝孔洞型储层和构造裂隙型储层。灰岩溶蚀孔隙（孔洞）型储层发育与加里东期、海西期不整合面没有密切的关系; 储渗空间发育受组构控制; 属低孔低渗、储集性较差的储层。灰岩岩溶缝孔洞型储层发育分布与加里东期、海西期不整合侵蚀面有着密切的关系; 发育分布非均质性强。灰岩构造裂隙型储层可发育高角度斜交或垂直层面的部分充填和未充填构造裂隙。白云岩内发育晶间孔及晶间溶孔、溶蚀孔洞、大型洞穴、风化裂隙、构造裂隙等5种储渗空间，它们构成白云岩岩溶缝孔洞型、白云岩溶蚀孔洞型两类储层。白云岩岩溶缝孔洞型储层发育与加里东期、海西期不整合面有着密切的关系; 其涉及厚度较小。白云岩溶蚀孔洞型储层的发育具有普遍性; 与加里东期、海西期不整合面关系不密切; 非均质性明显。白云岩溶蚀孔洞型储层在寒武系及下奥陶统广泛发育, 孔隙度较高, 渗透率较低，是该区最值得勘探的储层类型。

LOWER PALEOZOIC CARBONATE RESERVOIR CHARACTERISTICS OF HETIAN PALEOUPLIFT AREA

Two kinds of Lower Paleozoic carbonate reservoirs,i.e.limestone reservoirs and dolomite reservoirs,are developed at Hetian Paleouplift area.The limestone reservoirs include the dissolved pore (pore-cavity) limestone reservoirs,karst fracture-pore-cavity limestone reservoirs and structural fracture limestone reservoirs.The development of the dissolved pore (pore-cavity) limestone reservoirs didn't relate to the Caledonian and Hercynian uncomformity surfaces;reservoirs' permeabilities and porosities were controlled by their sedimentary fabrics;and they are belonged in the poor reservoirs with low permeability and low porosity.The development and distribution of the karst fracture-pore-cavity limestone reservoirs were closely related to the Caledonian and Hercynian unconformity surfaces,they having strong heterogeneity.The partially-filled and unfilled high-angle oblique or vertical fractures are developed in the structural fracture limestone reservoirs.Five kinds of storage-permeability spaces.i.e.intercrystalline pores/intercrystalline solution pores,dissolved pores and cavities,large-scale cavities,weathering fractures and structural fractures,are developed in dolomites,of which two kinds of dolomite reservoirs,i.e.karst fracture-pore-cavity dolomite reservoirs and dissolved pore-cavity dolomite reservoirs,are composed.The development of the karst fracture-pore-cavity dolomite reservoirs was closely related to the Caledonian and Hercynian unconformity surfaces,their thicks being small;and that of the dissolved pore-cavity dolomite reservoirs was of universality and didn't relate to the Caledonian and Hercynian unconformity surfaces,their heterogeneity being obvious.The dissolved pore-cavity dolomite reservoirs are worthy to be explored for at this area,because they are widely developed in Cambrian and Lower Ordovician and are possessed of relatively high porosity and relatively low pemeability.
