Sediment-hosted copper deposits are mainly postsedimentury.The ore-forming elements andfluid are originated from sedimentary basin. The coarse elastic rock with higher porosity and permeability than the upper and lower sedimentbed is the passase of fluid and the reservoir of sediment-hostedcopper depositS. Above the ore housing beds,there is a red fine-grained elastic rock series of 3 km thickness consisting of marlite, mudstone, siltstone, carbergillite and evaporite, acting as a water-resistinglayer. Hydrothermal alteration occurs in the coarse elastic sediments with Cu-bearing sulfides. Red ciastie rocks are intersected with white sandstone transversally and vertically. Cu-bearing sulfides are associated mainly with iron--bearing carbonate cements and Carbonatite veins. The Cu-bearing fluid flows along the permeable coarse elastic beds and precipitates Cu-bearing sulfides along epicontinents,upwarping zones,karst caves and folded-faulted zones.

Being influenced by Landei Fracture of Triassic in Lunnan area, the elevations in the both sides on the fracture are large enough to make the alluvial fan to enter directly the lacustrine basin and to form the tan delta group deposition.The fan deltaic body can be divided into three subfacies,named fan delta plain,fan delta front and pro-fan delta.Subaquous distributary channel sand bodies in the fan delta front are most important reservoir of oil and gas. The developing area of reseroir is located at SangTamu Horse Belt and the southern port.The kinds of reseroir rock are mainly fine-coarse grained lithic sandstone with lower maturity of the mineral and texture,containning quarts 15~60%,feldspar 10~25 %,rockclast 35~75%The most important reservoir space is secondary solution pore, including intergranular solution pore, intraparticalar solution pore, oversize pore, cement - dissolved pore, secondly micro - pore,primary pore and fissures.The Triassic reservoir are characterized by deep burial, high porosity and good permeability,burial depth 4200~5400m,peosity of 15~28. 45%,permeability of 10~4317' 9 × 10-3um2.Finally the origin of high porosity and good permeability of Triassic reservoir is discussed under such a baital depthi:1. Coarse grain reservoir sediments; 2. Usually less than 5% of clay content; 3. With thick mudstone (12~175m)between sandbeds ; 4. Increasing reservoir space because of the clastic grain dissolved by organic and inorganic acids ; 5. Most kaolinite is of porphyritic texture,so it is not easy for them to fill the pore and throat; 6. Lower geothermal gradient and deep burial in high speed and short period, etc.

轮南地区三叠纪时由于受轮台断裂影响,断裂两侧地形高差大,冲积扇沉积直接进入湖盆,形成扇三角洲沉积体群。扇三角洲沉积体明显地可划分为:扇三角洲平原亚相、扇三角洲前缘亚相和前扇三角洲亚相。扇三角洲前缘亚相中的水下分流河道沉积砂体是主要的油气储集体,储集砂体最发育地区位于桑塔木断垒带及以南地区。储集砂岩类型主要是矿物和结构成熟度较低的细─粗粒岩屑砂岩,石英含量15~60%,长石含量10~25%,岩屑含量35~75%。储集层的储集空间以次生溶蚀孔为主,其中包括粒间溶孔、粒内溶孔、超大孔隙、胶结物溶蚀孔、微孔隙,其次是原生孔和裂缝。轮南地区三叠系属深埋、高孔、高溶储层特征,埋深4200~5400m,其储集砂体,泥质含量低,小于5%。有机酸和无机酸对颗粒的溶蚀,扩大了储集空间,粘土矿物中绝大部分为斑点状高岭石,不易堵塞孔隙和喉道,低的地温梯度和短期的深埋等使三叠系储层具备高孔高渗的特点。孔隙度为15~28.54%,渗透率为10~4317.9×10-3um2。

ongpu depression (DP) is situated in southern part of Bohaiwan rift, in which main oil and gas accumulations show deeper burial than in other Cenozoic basins.of eastern China. The basin-fill sequence consists of Lower Tertiary of 4000-6000m in thickness, characterized by fine elastic rock intercalated thin halite and gypsum layers of lake fade:, and Upper Tertiary of 1400-2100m in thickness, characterized by grey-variegated elastic rock of fluvial factes. The deeply buried reservoirs generally belong to Sahejie Formation of Lower Tertiary in DP.Based on statistics of reservoir characteristics and thinsection analysis, secondary reservoirs occur in three zones (SA, SB and SC) from shallow burial to deep one.In case of wenliu area, pore texture and diagenetic features of the reservoirs show:(1)the zone SA-buried in 1800-2800m: more mixed genetic pores in which secondary pores resulted from strong dissolution of early carbonate cements and weak framework feldspar dissolution (FGD); a lot of intergranular pore type and enlarged one; (2) the zone SB-buried in 2800-3600m: rich in secondary pores resulted mainly from dissolution of carbonate cements; a lot enlarged intergranular pore type;(3) the zone SC-buried in 3600-> 5000m: much more pores resulted from destroyed grains than the zone SB, but less porosity and permeability.Combined with methods of scanning electron microscopy, electron probe. stable isotope and hydrocarbon-bearing inclusion analysis. different genesis of the above three zones are known. I. The genesis of SA minily attributes to strong dissolution of caronate cements caused by organic acids (esp. dicarboxylic acid); however, weak dissolution of aluminum-silicate minerals occurs in the zone SA, which may be responsible for the following factors: higher concentration of calcium and magnesium canon in pore fluid, higher content of elastic feldspar in mudstones, and thermal decomposition of carboxylic acid.II. Decarboxylation of organic acid increases in SB zone, which makes the rapid elevation of Pco2 and the transition from externally buffering carbonate system to internally buffering one, therefore the secondary porosity is mainly caused by dissolution of carbonate cements resulted from carbonic acid. Especially, abnormal high fluid pressure develops in the zone, which not oilly preserves initial pores but increases the dissolution ability of acidic fluid.III. Besides preservation of abnormal high fluid pressure to initial pores, carbonate-clay mineral reactions and thermochemical sulfate redox may produce CO2 and H2S to form acidic fluid environments, which may promote the development of secondary porosity in the zone SC.Additionally, coal seams of Carboniferous-Permian Period found at the base of DP may be of important significance to development of dissolution in the deeply buried reservoirs because of CO2 released from coalification.Synthetical analysis shows that the SA and SB are of superior reservoirs for oil and gas, however only gas usually accumulated in the SC. There are favourable conditions in the SB and SC where oil and gas accumulations with high pressure may develop.

东濮凹陷油气储层埋藏深、总厚度大、次生孔隙发育。据物性剖面和成因研究,由浅至深(1800->5000m)次生储层可划分三带:(1)SA带──表现为有机酸(尤双羧酸)及碳酸对碳酸盐胶结物及骨架长石颗粒的溶蚀;(2)SB带──碳酸对碳酸盐胶结物的溶蚀和异常高压保护;(3)SC带──异常高压保护及无机酸对胶结物的溶蚀。研究表明,高压流体及无机酸(H2CO3和H2S)对东濮凹陷深部储层的形成具有重要意义。
