Light hydrocarbon (methane, ethane, propane, butane and CO2) test and C isotopic analysis of CO are conducted for over 100 lower-layer atmospheric samples from the East china Sea slope and the Okinawa Trough. The results show that the lower-layer atmosphere mainly consists of CO2 and then of CH4. and the CO2 concentrations are calculated to have a high average value of 0.87 omega/10(-2) about three times that of the regional background (0-3 omega/10(-2)). The result also shows that the average value of C isotope - 20.8 x 10(-3) is given to the CO2, inferring that it is inorganic gas. Thus, for the future 's work in the Okinawa Trough, special attention should be paid to CO2 hydrate, which is very possibly an important hydrate type.

对川西坳陷异常地层压力的研究一直存在不同观点 ,本文认为 ,高异常地层压力的形成机理具有 3种基本类型 ,即单相流的异常地层压力 (时间变化的函数 )、常规圈闭条件下两相流的异常地层压力 (与时间变化无关但其分布具有局限性 )以及致密储层条件下两相流的异常地层压力 (与时间因素无关且表现为区域性特点 )。川西坳陷三叠系和侏罗系地层严重致密化 ,生烃过程对地层增压作用具有重要影响 ,现今异常地层压力的形成主要取决于流体在储层孔隙中的流动方式以及由此所产生的能量交换 ,取决于致密储层条件对已形成高异常地层压力的封闭保存过程 ,因此川西坳陷现今异常地层压力的形成在原始动力类型上具有多因素复合性 ,研究表明 ,异常地层压力分布与天然气聚集之间具有复杂关系。

In the processes of discrimination between oil-cracked gases and kerogen-cracked gases,Behar and Pinzgofer et al.'s results were adopted in the former researches,in which the ratio of C2/C3 is basically a constant while the ratio of C1/C2 gradually increases in the course of primary cracking of kerogen. Otherwise in the course of secondary cracking of oil,the ratio of C2/C3 increases rapidly while C1/C2 keeps relatively stable. Our study on analogue experiment shows that,whether it is oil or kerogen,in its process of gas generating by cracking,the ratios of C2/C3,C1/C2 or C1/C3 will all be increased with the growth of thermal conditions. In comparison,the ratio of C2/C3,which is affected by genetic type to some comparatively less extent,mainly responds to the maturity of gases,while the value of C2/C3 is about 2,and that of C2/iC4.is about 10,and the corresponding value of Ro is about 1.5%―1.6%. The influence of gas source on C2/C3 is less than that of gas maturity,otherwise C1/C2(or C1/C3) is obviously affected by cracking matrices. The ratios of C1/C2,C1/C3 of oil-cracked gases are less than that of kerogen-cracked gases,under the condition that the ratios of C2/C3 are similar in value,so are the value of dryness indexes. There exists wide diffidence between this view and the former discrimination method in theory. The analysis of the spot sample indicates that we can apply the above basic view to dealing efficiently with the problem of the discrimination between oil-cracked gas and kerogen-cracked gas.

由于CO2气体与常规天然气性质存在较大差异,使得富含CO2的气藏与常规气藏相态特征不同,导致CO2含量影响气藏的开发指标的变化。为此,以校正过相态的计算模型为基础,研究了等温条件下不同CO2含量天然气相态变化特征、不同温度下含CO2天然气相态变化特征及相态变化对开发指标的影响。结果认为:无论是气藏渗流还是井筒流动过程中,富含CO2的火山岩气藏的相态计算都必须考虑偏差因子、黏度和密度随CO2含量的变化;在压力小于30 MPa时,井筒流动要考虑体积系数的变化;气藏的稳产期、稳产期末采出程度和预测期末采出程度随CO2含量的增加不断降低。该研究成果对富含CO2天然气藏的开发具有指导意义。

Two ductile shear zones trending EW and NNE respectively not only controlled the tectonic framework of the northern North china, but also constrained the geody-namic background for gold mineralization in this region. Field observations and microstructural analyses reveal that the EW trending ductile shear zones are mainly contributed to dextral compressional deformation resulting from top-to-the-southeast oblique thrust shearing, whereas the NNE trending ones are genetically related to sinistral strike-slip and extensional faulting. One sample from the former yielded an 4.Ar-39Ar plateau age of (219±4. Ma (Bi) and two samples from the latter gave 4.Ar-39Ar plateau ages of (116± 2) Ma (Bi) and (127±3) Ma (Bi). These ages provide constraints on the top-to-the-southeast oblique thrusting event occurring in Late Triassic and the sinistral extensional and strike-slip faulting event which occurred in Early Cretaceous.

Following analyses of the abnormal high pressure distribution characteristics, based on the geological characteristics, tectonic stress field and physical simulation, we investigated the formation mechanisms of abnormal high pressure and its impacts on hydrocarbon accumulation in the Kuqa foreland thrust belt. The abnormal high pressure appears at the bottom of the Paleogene and obviously exists in the Triassic and Jurassic. However, the pressure coefficient in the Triassic and Jurassic is lower than that in the Cretaceous and at the bottom of the Paleogene. Horizontally, the abnormal high pressure distribution is characterized by E-W orientation zoning. The maximum pressure coefficient lies in the Kelasu-Dongqiu-Dina tectonic zones in the center of the Kuqa foreland thrust belt and decreases away from the tectonic zones. The formation of abnormal high pressure was mainly related with the intense tectonic compression in the Early Pleistocene time, and tectonic uplifting, undercompaction and hydrocarbon generation were secondary factors contributing to abnormal high pressure. Under the rapid and intense tectonic compression in the Early Pleistocene, the rock framework firstly undertook 1/4.of the compression stress and the other was borne by the pore fluids. Due to the presence of great seal of gypsum-salt or gypsum-mudstone beds in the Paleogene, the pressure of pore fluids increased rapidly and led to the abnormal high pressure in the Kuqa foreland thrust belt. The abnormal high pressure has important impacts on hydrocarbon accumulation. It is one of the necessary conditions for formation of large oil and gas fields in the Kuqa foreland thrust belt.

Water quality parameters such as pH, DO, COD, PQ4.- P, SiO3 - Si, NO2 - N, NO3 -N in the Haikou Bay were monitored respectively before and after Typhoon 9618 occurring on Sep. 18, 1996. Based on the statistics of typhoon in the Haikou Bay and numerical calculation of stormy current, the mechanism of water quality variation caused by typhoon is discussed. The typhoon impact on the Haikou Bay usually appears between July and November, most usually between August and October. The monitoring results before a typhoon were different from that. The stormy wave and windstorm cur-rent stir up the sediment in near-shore bottom and make the bottom water mix with the surface water strongly, specially windstorm current with strong velocity at the head of the bay stirs up higher pollutants sediment near sea area of sewage outfall, and heavy rain with typhoon carries the pollutants from land through the Nandu River to the Haikou Bay, so the contents of COD, PO4.- P, NO4.- N, NO3 ~N, SiO3 after a typhoon are higher than those before. Windstorm current is violent, which makes offshore high DO water exchange more frequently with inner bay water and oxygen in the air dissolves in sea water faster, so DO content after typhoon is higher than that before typhoon. This strong action of water exchange also causes lower pH change before and after the typhoon.
