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.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.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。

Depositional characteristics and petroleum geological significance of wetland

Wetland is a new type of sedimentary facies proposed for the first time in this paper. It is a type of sedimentary environment, transitional between land facies and water (sea or lake) facies. In this paper, wetland is redefined as “a type of sedimentary environments whose ground surface is flat and wet throughout the year, which may be covered with very shallow water (less than 2.m deep), and is covered with lush plant growth”. Wetland is reclassified into two types, swamp wetland (swamp in brief) and wet plain wetland (wet plain in brief). Swamp deposits are coal, while wet plain deposits are dark colored mudstones or silty mudstones rich in plant fossils and carbon debris. The deposits of wet plain are different from those of lake and floodplain in the abundance of plant fossils, color, resistivity well logging curve, and other sedimentary characteristics. In boreholes, resistivity logging can be used to distinguish between wet plain mudstones and lake mudstones. Understanding the sedimentary characteristics of wet plain wetland can help to identify wet plain deposits which were formerly classified as floodplain or lake deposits. This will help to reconstruct the palaeogeography and to understand the history of basin and climate evolution accurately, and is especially important in evaluation of the hydrocarbon generating potential of a basin. With the Jurassic Sangonghe Formation of the Yanqi Basin as an example, the identification characteristics of wetland are described.

This paper presents a new aquathermolysis study of conventional heavy oil in superheated steam. A new high temperature autoclave was designed, where volume and pressure could be adjusted. Aquathermolysis was studied on two different conventional heavy oil samples under different reaction times and temperatures. Experimental results show that aquathermolysis does take place for conventional heavy oil. As reaction time increases, the oil viscosity reduces. However, the reaction will reach equilibrium after a certain period of time and won＇t be sensitive to any further reaction time any more. Analysis shows that, while resin and asphaltenes decrease, saturated hydrocarbons and the H/C ratio increase after reaction. The main mechanism of aquathermolysis includes hydrogenization, desulfuration reaction of resin and asphaltenes, etc.

充气欠平衡钻井技术应用于水平井或大斜度井,将是拓展欠平衡钻井应用领域的重要方向之一。目前注气方式主要是钻柱注气和环空注气。采用钻柱注气方式,常规井下动力钻具和泥浆脉冲随钻测量工具无法正常工作,而现有的环空注气方式(如寄生套管、双层套管),由于成本高,技术问题多,应用不够广泛。由此,结合欠平衡钻井和水平井的理论和实践,提出了附加套管环空注气方式,并针对其关键技术进行理论分析和论证。该注气技术克服了钻柱注气的特殊问题,形成一套实用的环空注气欠平衡钻水平井技术。

中国陆核是全球9大陆核中最小的也是唯一一个"四面受挤"的陆核。这种特殊的地球动力学环境,孕育出众多世界知名的地质学家,创建了具有"中国特色"的地质学理论,极大地促进了我国地质理论的发展。正如恩格斯所指出,生产的发展离不开高度发展的理论,同样,中国油气资源的持续发展,也需要具有"中国特色"石油地质理论作指导。现有的成盆、成烃、成藏理论受到了严峻的挑战,愈来愈多的资料证实了烃类无机成因的可能性,这正在深刻地改变着现有的油气地质理论基础。

"质疑"一文认为Wang-Li模型存在数学原理的错误,模型是不成立的,应用实例结果也是不可信的。仔细地阅读了该文,并未发现其中有否定Wang-Li模型实质性的理由与论据。针对该文提出的3个问题,对模型结构进行了深入理论分析与应用实践检验,进一步证明了Wang-Li模型的数学原理是正确的,结构是严谨的;当模型积分下限t=0时,Np0不为零;常数项C为大于-1的数值时,也不会出现难以置信的结果。

Micro-geological causes and macro-geological controlling factors of low-resistivity oil layers in the Puao oilfield

引用

Petroleum Science 2009年第3期6卷 246-253页

作者： Tan Fengqi Li Hongqi Liu Hongtao Jiang Fucong Yu Hongyan School of Resource and Information Technology China University of Petroleum Beijing 102249 China State Key Laboratory of Petroleum Resource and Prospecting China University of Petroleum Beijing 102249 China The No.7 Oil Production Factory Daqing Oilfield Company PetroChina Heilongjiang 163515 China

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.

We analyze the excess area and depth to detachment method developed by Epard and Groshong （1993）, and apply it to the sand box model of Ge et al （2.04. to illustrate that inadequate consideration will affect the calculation of true depth to detachment. Using the data of Yu et al （2.06） to fit linear regression lines, we obtain the depths to detachment of Kela-2. Misikantage anticline and Dongqiu-8 structures, 115.74.m, 14.17km, and 75.4.km below the reference level （Cretaceous bottom） respectively with the excess area intercept equal to zero. However, the calculation results of depth to detachment in Yu et al （2.06） are based on excess area intercept unequal to zero.
