Reefs, reef-mounds and lime mud mounds are all carbonate buildups, and the reefs and banks are important targets for petroleum exploration The reefs, banks and mounds should be divided from each other not only in theory, but also in exploration practice, because of so many differences in sedimentary compositions, fabrics, environments, distribution in time and space, and the characteristics of petroleum geology If the original reef or bank itself was fine reservoir rocks, then it would become a better reservoir after the reservoirconstructive diagenesis The formation of a high quality carbonate reservoir is controlled by two factors: the sedimentary microfacies and the reservoirconstructive diagenesis The first is the basis for the formation of a high quality reservoir, and with the high energy reefbank facies as the best; the latter includes the cataclasis, the dolomitization and the karstification The dolomitization and karstification are the best for the formation of a high quality reservoir The karstification has the widest distribution, profoundest effect, and plays a vital role in the high quality reservoir forming The karst types are quite rich in the limestone reef or bank reservoir, including synsedimentary karst, penesedimentary karst, supergene karst and hydrothermal karst, and so does the dolomitization reef or bank reservoir The formation mechanism of synsedimentary karst and penesedimentary karst is related to the short time exposing and leaching of the cyclical highfrequency shallowupward sequence when the reefs or banks are forming The supergene karst is controlled by the exposing and leaching of tertiary cyclic sequence type I interface after the reefs or banks forming Thus, there developed a great deal of secondary corrosion pores, corrosion fractures and huge caves besides some original pores remained in the reef and bank reservoir Scarcely there are any original effective pores in reefmounds and lime mud mounds, especially in senkes among mounds, but secondary pores could be formed by karstification, and there would likely develop source rocks with high organic abundance

礁、礁丘、丘同属碳酸盐建隆，礁、滩是重要勘探目的层。但各自在沉积组分、组构、环境和时空分布，以及油气地质条件上迥然不同，因而无论从理论还是勘探实践上，都有必要将其各成体系划分开来。礁滩自身为好储集岩，当建设性成岩作用叠加后可形成好的储层。碳酸盐岩优质储层形成，主要受沉积微相与建设性成岩作用两大因素控制。前者是基础，并以高能的礁滩相带为最好；后者主要包括破裂、白云石化和溶蚀三大类，并以白云石化或溶蚀为最优，其中的溶蚀分布最广泛、影响最深刻而对优质储层形成起决定性作用。礁滩储层中的古岩溶类型最为丰富多彩，包括同生期、准同生期、表生期和埋藏期热流体岩溶的所有类型，白云岩化礁滩体也不例外。其中，同生准同生期岩溶的形成机制与礁滩沉积时高频层序旋回向上变浅序列的短暂暴露淋溶有关，表生期岩溶则受控于礁滩沉积后三级层序旋回Ⅰ型界面的暴露淋溶。由此，导致礁滩储层中除了可以也是唯一保存原生孔隙外，还发育了次生溶蚀孔洞缝和大型溶洞。礁丘、灰泥丘尤其是丘间洼地中发育高有机质丰度烃源岩；它们自身没有有效的原生孔隙，但岩溶作用可以形成次生孔隙。

The World Trade Organization was precisely acknowledged the technical trade barrier reasonable permitted its existence at the same time, simultaneously also saw the technical trade barrier unreasonable has at the same time formulated "Technical Trade Barrier Agreement", came the standard and limits various member nations the technical trade barrier behavior, guarded against stops appears to technical trade barrier abusiveness

世界贸易组织正是承认了技术性贸易壁垒合理的一面而允许其存在，同时也看到了技术性贸易壁垒不合理的一面而制定了《技术性贸易壁垒协议》，来规范和限制各成员国的技术性贸易壁垒行为，防止出现对技术性贸易壁垒的滥用

The first one is capital barrier, which means a large amount of initial capital for the perfect monopolizer. This prevents the common enterprise from entrance. The second is the technical barrier, i.e. the monopolizer is in control of certain technology and knack while other enterprises not, and then the market naturally become a monopoly market. Scale economy is the most studied technical barrier. The third one is law barrier, i.e. some exclusive patent rights are protected by the law. For example, patent and copyright are the monopolizations protected by the law. The fourth one is tactic barrier, even without any of the above mentioned barriers; it can also set up barriers through other ways, such as huge amount of advertisement investment.

首先是资本壁垒，即完全垄断企业的起始资本量很大，因此一般的企业难以进入；其次是技术性壁垒，即垄断者掌握了某种生产技术和诀窍，其他企业则没有，这个市场也就自然成了垄断市场，规模经济是一种被研究得最多的技术性壁垒；第三是法律壁垒，有些独家经营的特权是由法律所规定并受到法律保护的，专利和版权就是法律特许的垄断；第四是策略性壁垒，企业即使没有上述三种壁垒，也可以通过其他方式高筑壁垒，例如巨额广告投入。
