In Maokou formation of Permian exist the main gas reservoirs in Sichuan basin. The factors controlling the reservoir characteristics are many and complex. In this paper, we mainly discuss the diagenesis of well Mile No. 87 in Dazu county in order to recognize the accumulation laws of gas reservoirs.By studying the cores and thin sections, we know that the main destructive factors for reservoirs are cementation, compaction, pressure solution, early stage destructive recrystal-lization and silicification; and... In Maokou formation of Permian exist the main gas reservoirs in Sichuan basin. The factors controlling the reservoir characteristics are many and complex. In this paper, we mainly discuss the diagenesis of well Mile No. 87 in Dazu county in order to recognize the accumulation laws of gas reservoirs.By studying the cores and thin sections, we know that the main destructive factors for reservoirs are cementation, compaction, pressure solution, early stage destructive recrystal-lization and silicification; and that the constructive factors for reservoirs are solubilization, dolomization, late stage recrystallization and structure fractures.Author suggests that in the exploration in Maokou formation more attention be paid to the pore-fracture pattern gas reservoirs. 四川盆地二叠系茅口组是主要的天然气产层,控制储层性能的因素较多且复杂。本文通过对川弥87井成岩后生作用的研究,认识该组气层的储集规律。 通过岩芯和簿片研究认识到,胶结、压实、压溶、破坏性重结晶、硅化等作用对储层起破坏性作用;溶解、白云石化、后期重结晶等作用及构造裂隙的形成对储层起建设性作用。作者建议,在研究区茅口组地层勘探过程中,应把注意力放在孔隙—裂隙型储层气藏上。 Using questionnaire and logical analysis,the author discusses the encouragement constructive factors and features of child gymnasts. At the same time, several problems, to which should be paid attention in conducting encouragement, are put forward in this paper. 采用问卷调查与逻辑分析的研究方法,论述了少儿体操运动员激励的构成因素,激励过程中的特点,以及进行激励时应注意的几个问题。 In this paper, two samples of attainment and diffusion were fetched for a selective reaction experiment on the past, present, and future altermatives of active vs. passive words. The findings not onlyconfirmed the existence of the constructive factors (extension, direction, and relatedness) of timeperspective, but also showed that, in terms of active and passive self-concepts, attainment tended totake the active one to present and future, leaving behind the passive one, while diffusion did theopposite.... In this paper, two samples of attainment and diffusion were fetched for a selective reaction experiment on the past, present, and future altermatives of active vs. passive words. The findings not onlyconfirmed the existence of the constructive factors (extension, direction, and relatedness) of timeperspective, but also showed that, in terms of active and passive self-concepts, attainment tended totake the active one to present and future, leaving behind the passive one, while diffusion did theopposite. The findings above gave a full display of the structuring force exerted by certain identitystatus on time experience and self-concept and the relative changes it brought forth on the nature of theindividual's time perspective. 以24个人格形容词为材料,对111名大学生被试进行了“过去的我”、“现在的我”和“将来的我”三择一式的迫选反应实验,再配合时间标定作业。结果不仅验证了前文的研究结论,即不同同一性状态的被试在时间透视的广度、方向及关联性等心理结构特征上存在差异,而已表明了整合自我信息的不同的功能机制。不过,这种差异主要体现在积极词上,在消极词上差异不显著。
