The assumption of constant rock properties in pressure-transient analysis of stress-sensitive reservoirs can cause significant errors in the estimation of temporal and spatial variation of pressure. In this article, the pressure transient response of the fractal medium in stress-sensitive reservoirs was studied by using the self-similarity solution method and the regular perturbation method. The dependence of permeability on pore pressure makes the flow equation strongly nonlinear. The nonlinearities associated with the governing equation become weaker by using the logarithm transformation. The perturbation solutions for a constant pressure production and a constant rate production of a linear-source well were obtained by using the self-similarity solution method and the regular perturbation method in an infinitely large system, and inquire into the changing rule of pressure when the fractal and deformation parameters change. The plots of typical pressure curves were given in a few cases, and the results can be applied to well test analysis.

The Tertiary strata in the Bohai Bay basin consist of the Lower Tertiary sequence deposited at the rift stage and the Upper Tertiary sequence deposited at the post-rift stage. The Lower Tertiary sequence is composed of the three second-order sequences Ek, Es4-3, and Es2.Ed. Every second-order sequence corresponding to one rifting episode can be divided into the lowstand, transgressive, and highstand third-order sequence sets, which are represented as sedimentary products of the initial rifting, lacustrine expanding and contracting stages. The late transgressive and early highstand sequence sets are favorable periods for forming regional source and seal rocks. Three sets of major source and seal rocks and four sets of source-reservoir-seal combinations are recognized in the Tertiary strata. Differences of Tertiary tectonic history in different sags or depressions result in differences of developing periods and features of source-reservoir-seal combinations.

The reservoir of Feixianguan Formation of the Lower Triassic in the Sichuan Basin is the deepest buried carbonate reservoir in china, with developed secondary corrosion holes, high quantities carbonate reservoir, maximum effective carbonate reservoir thickness. Also Feixianguan gas reservoir has the highest quantities of H2.. research discovers that there are close relationships between the formation of reservoir and H2.. The mutual actions between acidity fluid and carbonate promoted the forming of secondary carbonate holes. Through the experiment of corrosion of the samples of Feixianguan carbonate reservoir in saturated aqueous solution of hydrogen sulfide, the porosity and permeability increased greatly, porosity increased 2. and permeability increased nearly two quantity degrees, also the density became light, which confirm the corrosion and reform actions of H2. to carbonate.

Quantitative description of the high-capacity channels in unconsolidated sandstone reservoirs, into which water was injected to improve oil recovery, is a hot topic in the field of reservoir development. This paper presents a novel approach to describing quantitatively the characteristics of connected macropores in unconsolidated sandstone reservoirs using in situ production data. Based on physical simulation for formation mechanisms of high capacity channels and interwell tracer test data, a mathematical model was established to describe high-capacity channels by grey correlation theory, flow mechanism of fluid in porous media and reservoir engineering, and a program was developed to describe quantitatively the channel characteristics. The predicted results were consistent with field monitoring data （80%）, so this model could be economically and effectively used to identify high-capacity channels.

2.世纪80年代以来,中国的石油工业处于储、产量相对稳定的壮年期。从1984年到2.04年,中国累计的探明地质储量和可采储量呈起伏不大的平稳升势。其中,东部老油区仍是增储的主力,2.年间地质储量年均增长4.6×108t,可采储量年均增量约为0.95×108t。西北区及海域地质储量年均增长分别为1.93×108t及1.11×108t,可采储量年均增量分别为0.396×108t及0.2.7×108t。从对未来经济发展更具影响的剩余可采储量看,中国石油剩余可采储量处于稳定的局面,2.年期间平均年增量仅为0.1×108t。东部老油区已处于稳产阶段后期,其剩余可采储量已开始下降,但西北和海域的增加弥补了东部的下降。今后东部老油区与西北、海域之间的减、增平衡状况决定着全国石油剩余可采储量和产量的变化趋势。为保持中国石油产量的进一步提高,今后应加强东部挖潜,开拓西北及南海深水海域战略接替区。

四川盆地下志留统龙马溪组发育富含有机质页岩。作为页岩气的源岩,该套页岩在盆地内分布广泛,厚度大,有机质含量高,有机质类型好,热演化程度高,生气潜力大;作为储层,页岩中孔隙和裂缝发育,为页岩气提供了充足的储集空间,并且等温吸附实验也表明,页岩具有较强的气体吸附能力;由于页岩的致密性及抗构造破坏性,本地区构造条件满足页岩气成藏要求。多口井下志留统页岩的气测显示也为页岩气的存在提供了有利证据。根据页岩厚度、有机碳含量、热演化程度和生烃强度等信息,预测宜宾—自贡—泸州一带及达州—万县一带为页岩气的有利勘探区域。
