Sustainable development pattern and the strategy in the Three Gorges Reservoir Areas

The development pattern, development situation, and existing problems of land exploitation in Zigui County, Three Gorges Reservoir Areas of China were presented. The sustainable development mode and its strategy in the Three Gorges Reservoir Areas was also discussed. A sustainable development framework for low mountain regions, middle mountain regions and high mountain regions was developed, and management countermeasures for structural optimization of complex ecosystems were advanced.

SWOT Analysis and Countermeasures of Industrial Development in Three Gorges Reservoir Area

Based on the introduction of the general situation of the research area,the SWOT analysis is applied to study the strengths,weakness,opportunities and threats of the industrial development in Three Gorges Reservoir area. The strengths are represented by the following four aspects:abundant agricultural resources,rich tourism resources,rich mineral resources and rich hydro energy. The weaknesses are analyzed from the following three aspects:the backward infrastructure,the acute conflict of the emigration of manufactures and the poor exploitation of advantageous resources. The opportunities of industrial development,which cover the opportunities bought by the guidance of national policies and preferential policies,by the improvement of traffic conditions in the reservoir area and by the completion and operation of the Three Gorges Reservoir Project. From the analysis of poor investment environment,irrational industrial structure and serious shortage of capitals,the threats of the industrial development are analyzed. In order to promote further the industrial development of the Three Gorges Reservoir area,the countermeasures are put forward. In the first place,optimizing the industrial structure and developing leading industries;in the second place,strengthening the construction of infrastructure and improving the investment environment;in the third place,optimizing human resources so as to provide intellectual support for industrial development.

Development unit division and favorable area evaluation for joint mining coalbed methane

Based on the productivity equation of coalbed methane (CBM) well, considering the impact of coal reservoir reformability on gas well productivity, the main production layer optimization index in the “three-step method” of optimal combination of production layers is corrected, and then the CBM production layer potential index is introduced to evaluate favorable areas for commingled multi-coal seam production. Through analysis of the key parameters of coal reservoirs affecting the CBM productivity index, a development unit division method for areas with multi-coal seams is established, and a quantitative grading index system is proposed. On this basis, the evaluation process of CBM development favorable area is developed: the mature 3-D modeling technology is used to characterize the reservoir physical properties of multi-coal seams in full-scale;the production layer potential index of each grid is calculated, and the production layer potential index contour under single-layer or commingled multi-layer production are plotted;according to the distribution of the contour of production layer potential index, the quantitative index of CBM development unit is adopted to outline the grade I, II, III coal reservoir distribution areas, and thus to pick out the favorable development areas. The practical application in the Yuwang block of Laochang in Yunnan proved that the favorable area evaluation process proposed can effectively overcome the defects of selecting favorable development areas only relying on evaluation results of a major coal seam pay, and enhance the accuracy of the evaluation results, meeting the requirements of selecting favorable areas for multi-coal seam commingled CBM production.

ASSESSMENT OF ECONOMIC DEVELOPMENT FOR THREE GORGES RESERVIOR AREA

Economic development of Three Gorges Reservoir Area remains backward. Here, per capita GNP and per capita national income are far less than that of Sichuan Province, Hubei Province and China respectively. Its industrial structure shows the characteristics of early phase of industrializing process. Economic development of the counties close to Chongqing City and Yichang City are more advanced than these counties located in the central part of the reservoir area. At present, economic development for the reservoir area runs into the difficulties: low profit in the leading industries, loss incurred in stateowned enterprises, small scale in most of enterprises and weak economic core of the cities and towns in the area. It is the best way for the reservoir area to wage protracted struggle against poverty and to carry out sustainable development strategy for its longterm development. For practising the strategy, it is necessary to lay stress on its infrastructural construction; meanwhile it should make up an optimal composition for distributing fund, allocating enterprises and choosing ownerships. It is also necessary to make strenuous efforts to promote the tertiary sector. In short, it can not catch with the development level of the country average unless exerting several decades efforts.

Dominating factors on well productivity and development strategies optimization in Weiyuan shale gas play, Sichuan Basin, SW China

Weiyuan shale gas play is characterized by thin high-quality reservoir thickness,big horizontal stress difference,and big productivity differences between wells.Based on integrated evaluation of shale gas reservoir geology and well logging interpretation of more than 20 appraisal wells,a correlation was built between the single well test production rate and the high-quality reservoir length drilled in the horizontal wells,high-quality reservoir thickness and the stimulation treatment parameters in over 100 horizontal wells,the dominating factors on horizontal well productivity were found out,and optimized development strategies were proposed.The results show that the deployed reserves of high-quality reservoir are the dominating factors on horizontal well productivity.In other words,the shale gas well productivity is controlled by the thickness of the high-quality reservoir,the high-quality reservoir drilling length and the effectiveness of stimulation.Based on the above understanding,the development strategies in Weiyuan shale gas play are optimized as follows:(1)The target of horizontal wells is located in the middle and lower parts of Longyi 11(Wei202 area)and Longyi 11(Wei204 area).(2)Producing wells are drilled in priority in the surrounding areas of Weiyuan county with thick high-quality reservoir.(3)A medium to high intensity stimulation is adopted.After the implementation of these strategies,both the production rate and the estimated ultimate recovery(EUR)of individual shale gas wells have increased substantially.

碳酸盐岩储层高精度构造应力场模拟与裂缝多参数分布预测方法及其应用

构造裂缝是碳酸盐岩的主要储集空间之一,局部应力导致的构造破裂是影响裂缝发育的重要因素。基于有限元方法的构造应力场模拟已成为构造裂缝预测的重要方法,但尚未能解决模型设置与实际地质情况相差较大、最优边界条件获取效率低以及构造裂缝发育的主控因素不清晰等问题。①引入非均质岩石力学模型构建方法和自适应边界条件约束算法以提升应力场模拟的精度,根据储层破裂率和断裂活动性等参数定量表征储层裂缝发育特征;②定量探讨走滑断裂变形特征的差异和应力扰动对构造裂缝发育的影响,优选控制构造裂缝发育的最强因素构建碳酸盐岩裂缝型储集体发育指数并定量研究其主控因素;③以储集体发育规模预测为基础,结合单井裂缝测井和岩心解释成果,建立不同级别碳酸盐岩裂缝型储集体的地质模式。将该方法在中国塔里木盆地顺北地区18号断裂带及邻区奥陶系碳酸盐岩储层中应用。结果表明,张扭段、平移段与压扭段的裂缝发育程度依次降低。地层变形幅度越大,裂缝发育程度越高。储层岩石力学参数、距断裂的距离、水平两向应力差、应力非均质性系数和综合破裂率被用于构建裂缝型储集体发育指数,其分级结果与实际地质情况匹配度较高。

普光地区千佛崖组致密砂岩-页岩气藏开发技术对策

普光地区侏罗系千佛崖组致密砂岩-页岩气藏为纵向叠合气藏,储层非均质性强,纵横向上储层特征和储集性能差异大,气藏开发潜力不明确,尚未形成开发井型、井网、井距等配套开发技术对策;且砂岩气藏与页岩气藏压力系统、气体运动方式不同,利用常规水平井压裂方式合层开采必定导致层间干扰和多余能耗,亟需采用最优开发方式。为此,文中参考鄂尔多斯盆地致密砂岩气藏水平井井位优选标准和四川盆地页岩气开发井型,根据储层展布特征,结合水平井与直井产能对比分析,优选水平井作为致密砂岩-页岩气藏的开发井型;采用类比法、经济评价法、单井产能法等,确定水平井水平段长度和合理井距;根据气藏特征,并借鉴同类气藏开发经验评价单井生产指标;在此基础上开展井位部署,评价气藏开发潜力。结果表明,采用2套井网分别开发千佛崖组致密砂岩气藏和页岩气藏,可建成年产能6.5×108 m3,这为普光地区千佛崖组致密砂岩-页岩气藏合理开发提供了有力支撑。

三峡库区香溪河流域滑坡类型及发育规律

三峡库区香溪河流域处在秭归向斜和黄陵背斜之间,地质环境脆弱,滑坡灾害频发,给香溪河流域村镇居民的生命财产安全及沿线公路的正常运营带来严重威胁。本文依据现场勘查,将滑坡分为两类,其中河流西侧的层状反向结构岸坡主要发育“弯曲-滑移”型滑坡,东侧的层状同向结构岸坡则发育“滑移-拉裂”型滑坡。对滑坡的空间分布状况、发育特征及数量作了统计与分析,结果表明:地形地貌是控制滑坡发育的因素之一,凸形坡、20°~40°的岸坡以及处于三面临空的凸岸山体均易发育滑坡;岩性与滑坡发育也有对应关系,泥砂岩互层的滑坡发育密度总体高于灰岩地层;滑坡发育尚与岸坡地质结构相关密切,泥砂岩互层同向结构岸坡的滑坡发育密度最高,泥砂岩互层反向结构岸坡孕育的滑坡规模最大;水库蓄水及公路建设是诱发滑坡的两大人为因素。
