惠民凹陷西南斜坡是一长期发育的稳定斜坡 ,其上发育不同产状的基底断层 ,构成复杂的断块构造。早第三纪断陷阶段 ,断裂强烈活动 ,对沙河街组沉积有明显的控制作用。晚第三纪、第四纪 ,大多数断裂均停止了活动。运用泥涂抹系数 ,对夏口断层封闭性进行研究 ,结果表明 ,以夏口断层的沙河街组三段中亚段为界 ,之上封闭性好 ,之下封闭性差。这一特征决定了临南洼陷沙河街组三段中亚段以上层位的油气无法穿过夏口断层 ,只能在断层上盘形成聚集 ;以下层位的油气却能穿过夏口断层 ,进入到西南斜坡。因此。

在国内发现的高温高压凝析气藏越来越多 ,所以须加强对这类气藏流体相态和物性的实验和理论研究。应用某气田地面油气样品 ,在实验室配制了高含蜡凝析气流体 ,研究了高含蜡凝析气在压力很高时的相态和物理参数。通过流体等质膨胀实验 ,确定了流体露点压力和相应的实验特性 ,给出了超高压下的压缩因子等数据。采用Dranchk等人的关系式计算了流体在超高压状态下的偏差因子。结果表明 ,计算值明显小于实验数值 ,误差大于 10 % ,且随压力的增大误差也增大。地层流体含有大量的蜡组分 ,在流体压力大于露点压力时。

Geochemical characteristics and origin of gases from the Upper,Lower Paleozoic and the Mesozoic reservoirs in the Ordos Basin,China

CPS/SEG 2004 International Geophysical Conference

作者： Huang Xiaoping Ren tao Research Institute of Exploration & Development xinjiang oilfield company Karamay xinjiang

＜正＞ Seismic attribute information is valuable information involved in the seismic reflection wave. As the intensity of exploration and development increases and the detailed characterization of reservoirs has been carried out, seismic attribute information has attracted great interest and attention of geophysical and geological experts. Although the modern seismic technology has rapidly developed and signal-to-noise ratio and resolution have been strikingly improved, the seismic attribute information, which can really inflect geotectonic geology, should not be ignored, since it can indicate the subsurface geological information about special geological phenomenon, sedimentary and fluid behavior etc. Taking Wuerhe formation in District No. 5 as an example, this paper presents conceptions of various common seismic attribute information, its operation and effect of practical application on oil-gas exploration and development.

Low-resistivity oil layers are often missed in logging interpretation because of their resistivity close to or below the resistivity of nearby water layers. Typical low-resistivity oil layers have been found in the past few years in the Putaohua reservoir of the Puao oilfield in the south of the Daqing placanticline by detailed exploration. Based on a study of micro-geological causes of low-resistivity oil layers, the macro-geological controlling factors were analyzed through comprehensive research of regional depositional background, geological structure, and oil-water relations combined with core, water testing, well logging, and scanning electron microscopy data. The results showed that the formation and distribution of Putaohua low-resistivity oil layers in the Puao oilfield were controlled by depositional environment, sedimentary facies, diagenesis, motive power of hydrocarbon accumulation, and acidity and alkalinity of reservoir liquid. The low-resistivity oil layers caused by high bound-water saturation were controlled by deposition and diagenesis, those caused by high free-water saturation were controlled by structural amplitude and motive power of hydrocarbon accumulation. Those caused by formation water with high salinity were controlled by the ancient saline water depositional environment and faulted structure and those caused by additional conductivity of shale were controlled by paleoclimate and acidity and alkalinity of reservoir liquid. Consideration of both micro-geological causes and macro-geological controlling factors is important in identifying low-resistivity oil layers.

油田开发规划决策支持系统是一项系统工程,其设计的知识面广,内容复杂。决策问题的核心是资源的合理利用和分配,单目标线性规划模型就是在定产量的基础上建立起来的一种资源优化分配方法,追求在一定产量的基础上力求成本最低。多目标线性规划模型则是追求产量最高、成本最低等目标而建立的一种分配模型。根据决策变量在约束条件的作用下,充分发挥油田的潜力,建立模型合理分配资源,达到最优化生产。这就为油田开发决策者制定规划方案提供了科学方法和理论依据。

吐哈盆地台北凹陷侏罗系水西沟群钻探发现较大规模的致密砂岩气藏,迫切需要在该区开展天然气成藏条件研究,寻找有利勘探区域。为此,从烃源条件、储层特征及分布等方面分析了该区2套主力产层(下侏罗统三工河组和八道湾组)的成藏条件,结果认为:①该区煤系烃源岩品质好、厚度大,生气强度大,富气条件优越;②储层分布稳定,厚度大,物性致密,常规气藏形成条件欠佳,但能形成致密砂岩气藏;③气藏类型为"先成型"致密砂岩气藏,存在2种不同的成藏模式。通过评价生烃强度、储层发育程度、源储配置关系等指标,划分出托克逊、苏巴什—连木沁等8个致密砂岩气有利勘探区域,其中的高渗透带及构造有利部位是"甜点"有利分布区,整体勘探潜力大。
