In turning point and anticlinal p1unging portion -microfracture development and low stress area,it is favorable to prospect a coalbed gas.

但由于煤的变质程度较低，煤质较差，加上逆掩断裂的挤压作用，使地层有效地应力较高、造成煤储层渗透性较差；再者，煤储层的含气饱和度较低，开煤层气的产出较为不利；但在构造的转折端及背科的倾伏部位，存在着微裂隙较发育的地应力低带，有希望找到煤层气勘探开发的有利区。

But ECT technology has the following characteristics: 1 the measured capacitance and its change induced by the measured material concentration variation are very small, but the stray capacitances of co-axial screening cable and CMOS switches are relative very large, so the capacitance detecting is easily affected by the stray capacitances, 2 the electric fields in the sensors detecting region is affected by the permittivity distribution, non-uniformity of the space responsive sensitivity is very high, and the image reconstruction is undetermined.

但由于ECT技术中，首先所检测的微电容量及其因物流相含率的变化所引起的变化量很小，而由相关的连接同轴屏蔽电缆与切换CMOS开关所引入的杂散电容远远大于测量电容，微电容的测量容易受杂散电容等的影响；其次，多电极电容传感器测量区内的电场受介质分布的影响，且测量区内的空间响应灵敏度极不均衡，其影响图像重建的不确定性；其三，ECT中的图像重建，由于其是一个欠定问题的求解，在迭代求解方法中，迭代的初值影响迭代过程收敛到近似解的速度；其四，对于气/固两相流应用而言，由于ECT系统在线标定的难以实现，管壁磨损等因素的影响制约该技术应用于生产工艺中气/固两相流的长期连续检测。

It is shown that in the basins in the Eastern China, onshore and offshore, the formation of CO2 reservoir is crust-sourced and crust-mantal-mixed-sourced, mainly controlled by local activity of hot fluid into the mud diapir area in multi-phase and multi-zones in physical-chemical mechanism of very thick marine calcareous sandstone and mudstone of Pliocene-Miocene. The volcano- and mantle-sourced CO2 in the Qiongdongnan Basin and Pearl River Mouth Basin is mainly controlled by magmatism and major faults which cut through the basements and link to the mantle gas.

研究表明，中国东部陆相断陷盆地与东海陆架盆地及南海北部陆架琼东南盆地东部和珠江口盆地的CO2气藏及高含CO2油气藏中CO2均属典型的火山幔源型成因，主要受控于幔源型火山活动脱气与沟通深部气源的基底深大断裂的导气配置作用，其运聚富集规律及控制因素与幔源型火山活动及深大断裂的发育展布密切相关，CO2气源主要来自地壳深部幔源火山活动所脱出的大量原始CO2；南海北部陆架西区莺歌海盆地CO2气藏及中国东部陆相断陷盆地部分高含CO2油气藏中CO2，则属于壳源型及壳幔混合型成因，CO2形成及运聚成藏，主要受控于火山侵入活动对碳酸盐岩的烘烤和泥底辟热流体晚期分层分块多期的局部上侵活动与沉积巨厚的海相含钙砂泥岩的物理化学综合作用，其运聚分布规律具多期和分层分区的特点。

The study shows that in various continental downfaulted basins in eastern China,the China East Sea basin of the southeast sea region and the continental shelf—Qiongdongnan basin and Zhujiangkou basin—of the northern South China Sea,CO2 in CO2 reservoirs and CO2-rich oil/gas reservoirs is of typical volcanic mantle-derived type and that its migration and concentration is mainly controlled by mantle-derived volcanism and gas-conducting distribution of deep basement faults connected with the gas source at depth. CO2 is mainly sourced from substantial amount of CO2 associated with mantle-derived volcanism at the deep level of the crust. CO2 in the CO2 reservoirs and CO2-rich oil/gas reservoirs in the Yinggehai basin on the continental shelf of the northern South China Sea is of crust origin and crust-mantle mixing origin and mainly controlled by local,layer-by-layer and zone-by-zone,multiple intrusion of late hydrothermal fluids in mud diapir areas and physico-chemical processes of very thick Pliocene-Miocene marine calcareous sandstone and mudstone.

研究表明，中国东部陆上诸断陷盆地与东南沿海海域的东海盆地及南海北部大陆架琼东南盆地和珠江口盆地CO2气藏及高含CO2油气藏中，CO2均属典型的火山幔源型成因，其运聚富集主要受控于幔源型火山活动与沟通深部气源的基底深大断裂的导气配置作用，CO2气源主要来自地壳深部幔源火山活动伴生的大量CO2；南海北部大陆架西区莺歌海盆地CO2气藏及含CO2油气藏中的CO2，属于壳源型及壳幔混合型成因，主要受控于泥底辟热流体晚期分层分块多期的局部上侵活动与沉积巨厚海相含钙砂泥岩的物理化学作用，其运聚分布具多期和分层分区的特点。

The electrolytic production are the middle matters of organic chloride and final matters of organic chloride besides dicarbonate . This may limit the application of electrochemical technology .Must consider the production and control of organic chloride when electrolysis organic wastewater concluding chloride ion.

苯酚和腐植酸在氯离子体系中的电解产物除了有CO_2这样的小分子气体外，还生成了有机氯中间体和最终产物，这可能会限制电化学氧化法的应用，在电解处理含氯的有机废水时必须考虑有机氯的形成和控制问题。

As the foaming agent is the continued increase in frother dosage of 400g / t, the gas holdup appears the phenomenon of axial turning point was not obvious, the axial distribution of gas holdup tends to uniform.

随着起泡剂用量的继续增加，在起泡剂用量为400g/t时，气含率出现轴向拐点现象不明显，气含率轴向分布趋于均匀。

The differences in reservoiring conditions of natural gas and oil, as well as the multicycle developments and evolution histories of major gas bearing basins in China, and the geological environments characterized by relatively active tectonic movements in later period have resulted in the forming conditions of gas fields in China to be more complicated than those in many basins all over the world.

由于天然气与石油在成藏条件上的差异和中国主要含气盆地多旋回的发展演化历史、晚近时期构造运动比较活跃的地质环境，中国气田形成条件较世界上许多盆地复杂和成藏类型较多。总结中国大中型气田的成藏历程，可以新近纪、古近纪和中生代为界将气田的形成归为 4类：1超晚期生烃成藏型；2晚期生烃成藏型；3早期生烃聚集和晚期定型成藏型；4早期生烃成藏型。在这 4类中，以晚期和超晚期成藏和定型为主且分布最广、天然气前景最好、是中国天然气最主要富集领域。早期生烃成藏型在保存良好的盆地也有较好的前景。

Along with horizon development well to implement, some problem became more and more gravity, such as sandbody'scale and sandbody'boundary was uncertainty and layer pressure was uneqilibrium for different well area development degree is not community. These taked a few difficulty of comprehensive evaluaterating, deploying horizon development well, adjusting well trackway for the gas field, and it might take any geologic risk.

随着该气田水平开发井的逐步实施，其含气砂体规模及砂体边界的不确定性以及由于各井块开发程度的不均一性而导致的地层压力不均衡等地质难题都日益显现出来，这些都给该气田的全面评价、水平开发井部署和井轨迹的调整带来困难，并可能引起更大的勘探开发风险。

Located offshore in the South China Sea, Yinggehai basin has a peculiar sedimentary, tectonic and evolution model. As a result, the basin is abundant in hydrocarbon resources. A series of oil/gas fields have been found, that are closely related to fault system and overpressure fluid activity in diapirs area.

莺歌海盆地位于我国南海海域，具有独特的沉积、构造和演化模式，因而烃源丰富，资源潜力巨大，在浅层已经发现了一系列与底辟区的断裂输导系统和超压流体的活动有着密切的联系的气田和含气构造。

Bright spots result from large changes in acoustic impedance and tuning effects, such as when a gas sand underlies a shale, but can also be caused by phenomena other than the presence of hydrocarbons, such as a change in lithology.

亮点是由大的声阻抗变化及调谐作用产生的，如含气砂岩上覆页岩的情况，亮点也可能是其它现象，而不是烃类的存在引起的。
