Study of forming mechanism of "chimney-effect" (CE) has important significance for basic theory and applications of non-seismic geophysical and geochemical methods locating oil/gas reservoirs. The theoretical basis of comprehensive evaluation of mechanism of CE using principles of magnetism, geochemistry and mineralogy has been reviewed, with the problems to be solved: (ⅰ) study for the relationship between process of oil/gas migration and geochemical field; (ⅱ) analysis of genesis of magnetic, geochemical and mineralogical anomaly; (ⅲ) interpretation of surface soil magnetism and geochemical anomaly combined with seismic data.

Gas resources in china arequite abundant,on the basis of 2.dround nation-wide oil-gas re-sources’ estimation result,the to-tal gas resources amount is 58.04trillion m~3. ranking in the 10thplace of the world ,in which the to-tal resouces amount on land is2..9 trillion m~3, that off shore is8.14 trillion m~3. But the gasproved degree in china is quite low at present. Emphasis is put on the elucidation of strategyin expanding our exploration from certain geologi-cal aspects and gas exploration in some new re-gions is approached in this paper.

The concept of hydrocarbon accumulation in network was presented on basis of the overall analysis of the formation and evolution characteristics of the continental faulted basin and of the systemic re-search on the major controlling factors on the hydrocarbon accumulation. The hydrocarbon accumu-lation in network can be defined as hydrocarbon accumulation in a three-dimensional network system which is constituted by the hydrocarbon migration passages under multiple dynamics,following the hydrocarbon generation from source rocks. The research shows that the hydrocarbon accumulation in network is composed of four elements,i.e.,hydrocarbon source (source rock kitchen),hydrocarbon accumulation terminal (trap),network pathway connecting source and terminal (transporting system),and network potential driving hydrocarbon migration in the network pathway (migration dynamics). Compared with other networks,hydrocarbon accumulation in network has three basic characteristics: the irreversible geological process of material and information flow in the network; the loss of material and information in the flow process in the network; the multiple dynamics in the flow process. Interac-tion of all the elements in the geological process can be called hydrocarbon accumulation in network. There are three basic models for hydrocarbon accumulation in network,that is,hydrocarbon accumu-lation in the network source area,hydrocarbon accumulation in the network pathway,and hydrocarbon accumulation in the network terminal. The key in the application of the hydrocarbon accumulation models in network in practice is to confirm the major accumulation stage and the function range of the four elements controlling the hydrocarbon firstly,to predict the profitable accumulation region by su-perposition of the favorable areas confirmed by four elements consequently,and to evaluate the oil-bearing property of the trap as well as confirm drilling targets. This paper takes the Dongying De-pression in the

Linear low-density polyethylene (LLDPE) was prepared by in situ polymerization using a dual-functional catalytic system containing Et(Ind)2.rCl2.MAO and Ti(On-Bu)4 /AlEt3 used as co-polymerization catalyst and dimeriza-tion catalyst, respectively. The catalytic system showed high activity and the polymer with low melting point, narrow molecular weight distribution (MWD) and low crystallinity was produced.

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.

关键词： Conventional heavy oil superheated steam aquathermolysis viscosity reduction

A finite volume method for the numerical solution of viscoelastic flows is given. The flow of a differential Upper-Convected Maxwell （UCM） fluid through an abrupt expansion has been chosen as a prototype example. The conservation and constitutive equations are solved using the Finite Volume Method （FVM） in a staggered grid with an upwind scheme for the viscoelastic stresses and a hybrid scheme for the velocities. An enhanced-in-speed pressure-correction algorithm is used and a method for handling the source term in the momentum equations is employed. Improved accuracy is achieved by a special discretization of the boundary conditions. Stable solutions are obtained for higher Weissenberg number （We）, further extending the range of simulations with the FVM. Numerical results show the viscoelasticity of polymer solutions is the main factor influencing the sweeo efficiency.

地应力研究结果可为煤层气评价选区提供重要的资料。对于井下某一煤层，通过测试和计算可得到地应力、地层压力、解吸压力以及据以上基础数据而得出的许多推算值。它们构成了一个复杂的力学系统从而影响煤层气的储存和产出。通常对上述数值进行分析时，特别是涉及到不同煤层和不同井的煤层之间的对比时，显得相当麻烦。介绍了一种煤层气井地应力评价图解法，既可对同一井的不同煤层，又可对不同地区不同井的煤层按深度将有关的各项力学参数在图上直观地表示出来，在图上进行煤层间各种数值对比十分方便。对美国、中国的５口代表井进行了作图分析，并结合各煤层的产气量，说明了地应力评价的重要性和作图法评价的有效性。
