摘 要：针对伊朗卡山探区勘探程度低、周期短、难度大、风险高的特点，通过地球物理资料，特别是地震资料的处理和解释，结合探区外围的地质调查和油气田资料，进行了油气藏圈闭可靠性、储集封堵条件、有效性及含油气性等方面的地球物理资料预测，探索出了一套早期勘探区域圈闭评价的新方法。

The traditional economic evaluation of oil/ gas exploration projects is a single analysis essentially: either by characterizing the investment return gained from the ex ploration projects, or by weighting the geologic risk borne by the projects.

传统的油气勘探项目经济评价方法基本都是单一的分析：或表征勘探项目所取得的投资收益，或衡量项目所承担的地质风险。

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。

摘要以宁夏、山东的煤矿地震勘探为例，介绍了复杂地表工区地震勘探的方法与地质效果。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
