在前人研究的基础上，应用高分辨层序地层学理论与研究方法，对松辽盆地南部西斜坡地区的青山口组地层进行了层序地层划分与对比工作，从中识别出6个具等时意义的层序界面，将其划分为5个中期基准面旋回（4级层序）。

Results Xunhua-Guide area is characterized by step-shaped low-relief at different elevation. The low-relief surfaces developed above the newer strata in sedimentary basin among the Oligocene to the lower Pleistocene are in higher elevation, but above the older strata, are in lower elevation. The elevations of all above low-relief surfaces are lower than those of the planation surface above the bedrocks in the thrust belts. The low-relief surfaces of terraces, developed on both sides of the deep-cutting valleys within the basins, are lowest in elevation.

结果 循化－贵德地区地形形态总体呈台阶状结构，在不同海拔高度存在低起伏地形；发育于盆地沉积地层之上的低起伏面表现为年代越新的地层之上低起伏面高程越高，越老的地层高程越低，并且它们均低于发育于逆冲带基岩之上的夷平面；发育于盆地深切河谷两侧阶地之上的低起伏面海拔高程总体较低。

On the basis of accurately calculating the parameters of formation water,the effects of these parameters on the effective porosities of rocks and the parameters of identifying gas reservoirs are emphatically analyzed.It is pointed out that in the strata containing salt-water,if the parameter values of pure water are used,the calculated effective porosities of the rocks and the calculated parameter values of identifying gas reservoir will be all reduced,which exerts a serious influence on the log recognition of gas reservoirs.

在准确计算地层水参数的基础上，着重分析这些参数对地层岩石有效孔隙度和气藏判识参数的影响，指出在含盐水的地层中，如果采用淡水参数值，其结果是使计算的岩石有效孔隙度和气藏识别参数值降低，严重地影响了气藏的测井识别。

CO2 and H2S exist in the hydrocarbon zone and foramtion water,as the accompany gases of petroleum and nature gaso or components of formation water,which will cause corrostion to the cement sheath under certain conditions of humidity and pressure.It will decrease the cement sheath's alkalinity,which results in the decrease of cement sheath's strength,permeability increase,and places a premium on fluid channeling and borehole wall sloughs accident in plastic formation,shortening the oil- gas well's production lifetime and giving rise to tremendous ecomonic losses.

CO2和H2S作为石油和天然气的伴生气或地层水的组分存在于油气层或地层水中，在一定的湿度及压力条件下会对固井水泥环产生腐蚀作用，从而降低水泥环的碱性，使水泥环强度下降，渗透率增大，并诱发流体窜流、塑性地层井壁跨塌等事故，从而缩短油气井的生产寿命，造成巨大的经济损失。

According to application of wire line formation tester , using data of formation pressure, mud pressure, etc to estimate reservoir property and fluid characteristics, examples validates the feasibility of using formation pressure to judge reservoir property.

Strontium isotope stratigraphy relies on the fundamental principle that the marine strontium is isotopically homogenous world-wide at any time and the 87Sr/86Sr ratio of strontium in seawater of geological history has varied through time. By means of the 87Sr/86Sr ratio of marine carbonate which should record the original composition of sea water, we can date the marine sediments, research global events, such as history of basin subside, sea level change, orogenic events and palaeoclimate variation.
