威远～安岳地区茅口组岩性致密，产气层段均发育岩溶。威远构造一直处于继承性隆起高带、现今构造完整且规模巨大、茅口组古风化壳岩溶储层发育有利，是油气富集的有利指向区域。古岩溶地貌是影响古风化壳岩溶发育及分布的重要因素，研究该地区茅口组古岩溶地貌对预测研究区岩溶储层的展布特征以及指导油气勘探提供了理论基础。论文具体分为五部分：

第一部分为绪论，从研究的目的与意义，研究现状，研究区基本情况这三个方面，收集和梳理了有关的资料，并提出了本研究的论文的研究思路、研究内容、技术路线。
第二部分为区域背景，对工区的地理位置，构造位置，构造演化历史，沉积特征、地层、岩性这四方面进行了研究。
第三部分为茅口组古岩溶特征及识别标志的研究，对四种古岩溶作用类型及其特征进行了分析，并茅口组岩溶古地貌的识别标志进行了总结。
第四部分为本次论文重点即古岩溶地貌恢复及其特征，根据恢复古地貌的原理，得出适合下二叠茅口组统古地貌的恢复方法为印模法，依据上覆地层沉积特征和茅口组地层沉积特征，选择上二叠统为基准面，然后用印模法恢复出的上二叠统沉积前茅口组的古地貌，并分析出古岩溶地貌与油气富集关系。
第五部分综合本研究的观点和论述，进行结论，并指出了研究的不足。

关键词：古岩溶、识别标志、古地貌、印模法

Answer 1

Weiyuan ~ Anyue region Maokou group lithology dense and gas production and development of both karst. Weiyuan structure has been in a succession of high-uplift zone, the current structural integrity and enormous scale, Gufeng Maokou group of karst reservoir of good shell, is pointing to the favorable oil and gas rich region. Ancient karst landforms that affect Gufeng shell of Karst and distribution of important factors, the study of the region Maokou group of karst topography of ancient prediction of the reservoir area of karst distribution of oil and gas exploration and guidance provides a theoretical basis. Specific thesis is divided into five parts:
The first part of the introduction, from the purpose and significance of research on the status quo, the study area basic situation of these three areas to collect and sort out the relevant information and put forward the thesis of this study of ideas, research, technical routes. The second part is divided into regional context, the work area location, structure location, tectonic evolution of history, the sedimentary characteristics, formation, lithology these four aspects of the study.
Part III is divided into Maokou ancient group of karst features and identification of the four ancient role of karst type and characteristics of and Maokou ancient group of karst landforms identifier was concluded.
The fourth part of this thesis is focused on restoration of ancient karst landforms and their characteristics, in accordance with the principle of restoring ancient landscape, draw for the Permian Maokou group EC ancient landscape of the way for resumption of an impression, based on a review on the formation and sedimentary characteristics Maokou Formation sedimentary characteristics, choice of Permian for the base level, and then use an impression to restore law on the Permian sediments forefront of the ancient landscape mouth group, and analysis of ancient karst landforms and rich oil and gas relations. Part V of this comprehensive study of the views and discussed, conclusions and pointed out the lack of research.
Key words: paleokarst, identification, the ancient landscape, an impression of law
