So supported by well core experimentation, the *** analyzed the logging response feature and mechanism of thin bed, and point out that many factors can affect the logging response of the reservoir, the main factor which mostly influence the logging response is the thickness of thin layer, and the content of carbonite have a great influence on the response of 3-porosity logging.we make use of core experimentation, combined with logging material, firstly the *** do the lithology correction and thinckness correction for resistivity curves, and based on the content of mud that derived from the core experimentation, the *** present the thickness correction model of gamma-ray logging and self-potential logging, and choose the appropriate ways to compute the carbonate content and using the value of mixed frame in order to correct the influence from the carbonite, based on this, the *** gives a effective methods to correct the thickness influence for 3-porosity logging.

本文首先以岩心实验结果为依据，对研究区薄层的测井响应特征和机理进行了分析，指出多种地质因素影响着储层的测井响应特征，而层厚是影响测井响应最主要的因素，且碳酸岩含量对三孔隙度测井的影响很大。利用岩心实验分析资料，结合测井资料，首先对电阻率测井曲线进行了岩性的校正和层厚校正；利用岩心分析泥质含量，研究了自然伽马和自然电位的层厚校正方法，并建立了层厚校正模型；在有效计算储层碳酸岩含量和混合骨架参数值的基础上，研究了针对碳酸岩含量对测井曲线的影响进行校正的方法，进而提出了一套对三孔隙度测井曲线的薄层层厚影响的校正模型。

Calidonian granites are widely developed in the Yema Nanshan area in the western segment of the Qilian orogenic belt. The geochemical characteristics of most of the granites are similar to those of adakites: SiO2≥56%, Al2O3≥15.0%, low MgO (average 2.04%), high Sr (257-889μg/g, average 546.42μg/g), low Y (7.1-25.3μg/g,average 16.67μg/g), average Sr/Y=5.89, no pronounced Eu anomaly and Sr positive anomaly. Adakites in this area have five rock types, quartz diorite, quartz monzodiorite, quartz monzonite, monzogrannite and hornblende granite. These rocks commonly contain hornblende, belonging to I-type granites.

提要：祁连西段野马南山一带发育大量的加里东期花岗岩，其中大部分花岗岩具有与adakite岩相似的地球化学特征，SiO2≥56%， Al2O3≥15.0％，低MgO（平均2.04％），高Sr(257～889μg/g，平均值546.42μg/g)，低Y（7.1～25.3μg/g，平均16.67μg/g），Sr/Y平均为35.89μg/g，Eu无明显负异常，Sr正异常，Adakite岩石类型有石英闪长岩、石英二长闪长岩、石英二长岩、角闪花岗岩、二长花岗岩，岩石中普遍含有角闪石，属I型花岗岩，地球化学图解反映该花岗岩形成环境为板块碰撞前的岛弧型，锆石U-Pb同位素年龄为444+38/-33 Ma，处在祁连造山带板块俯冲收缩阶段，因此可以推断野马南山埃达克质Adakite花岗岩是俯冲板片部分融熔和壳幔岩浆混合形成的。

Its form and intensity in different areas of the buried hills and different evolution stage are very different and has caused the change of reservoir properties, namely increasing heterogeneity: intensive and selective corrosion has caused obvoius enlargment of the pre—existing pores and increase of permeability of algal sparry dolomite located in main permeable course and dilution zone of water injection, precipitation of secondary minerals has caused the reduction of porosity and decrease of permeability in the upper part of oil pool and oil—water contact.

古潜山不同区段在油藏保存和开发期，其水—岩作用方式与强度具有明显的差异性，导致储渗性能的非均质性增强：在主渗流带中的亮晶藻屑白云岩由于受到多期强烈的选择性溶蚀作用，孔洞发育，渗透性增强；而在油藏顶部和底部油水混合带中，水—岩作用以次生矿物沉淀为主，孔隙被充填，渗透性降低。

According to the sequence model, the topography is expanse and flatness, there are relative shallow water, stable structure, flattened basement in intercontinental rifting basin, and the provenances changed gradually from terrigenous clasts to intra-basin carbonate. So, there are some corresponding characteristics in sequence genetic framework:① Sequence material components are carbonate rocks, and mixed sedimentary series of carbonate rocks and clastic rocks.

就层序模型来讲，陆内裂陷盆地地势宽缓，具有水体相对浅、构造稳定、基底平缓、物质来源由陆源碎屑逐渐向盆地内的碳酸盐转化，因此，其相应的层序成因格架具有如下主要特征：①在层序物质构成方面，主要由碳酸盐岩构成，其次是碳酸盐岩—碎屑岩的混合沉积岩系。
