随着细观损伤岩体力学的发展，采用损伤观点解决深埋隧道围岩破坏问题逐渐显示出其优越性，但目前仅在均质性假设的基础上对应力状态和破坏判据进行研究，缺乏对其破坏全过程的相关研究。

As pH value varied in the course of diagenesis,reservoirs experienced one to three cementations or dissolution generations.Lots of secondary dissolution pores developed in the late diagenetic stage,because of the acidic mediums in the process of generation and migration of oil and gas. The anhydrites deposited in the dissolved pores resulted in the heterogeneity of secondary pores.

储层在成岩过程中受地层水pH值变化的影响，经历1~3个世代的胶结或溶蚀作用，其中在晚成岩期油气生成和运移过程中形成的酸性成岩环境对早成岩期生成的碳酸盐岩胶结物和储层中的长石矿物溶蚀，因而产生了大量的次生溶孔，但随后在溶孔中沉淀了不等量的硬石膏，导致了次生孔隙的非均质性。

A new implicit pressure calculation method and relevant percolation rule are introduced taking account of the advantages of methods suggested by King, Sorbie and Stenby. Simulation methods for various boundary conditions (fixed pressure or fixed flow rate) and well pattern (line drive, five-spot pattern) are presented.

Attribute projection, pseudo-constant time slice and high resolution seismic data are integrated to describe the gulches in each gas layer.

通过对泥流冲沟带中储层纵、横向分布规律的认识，描述了造成该气田气层气体组分差异的储层非均质性影响因素。

The phenomenon is caused by the control of formation water on the hydrogen sulphide formation and by the incomplete separation of water and gas due to strong heterogeneity of reservoirs.

结果表明，地层水对硫化氢生成的控制作用和储层强非均质性导致的气水分离不彻底是&硫水耦合&的关键。

A new high technology-Imaging well logging (Full borehole formation Micro-resistivity Image) not only can, however, displays all kinds of fractures and vugs, but also calculate some parameters related to fractures and analyze vugs.

碳酸盐岩、火成岩等复杂性油气藏具有岩性、孔隙空间结构复杂、非均质性强等特点，单纯用常规测井技术很难对这些油气藏进行准确评价，必须借助于成像测井等新技术资料。

Remaining oil mainly forms under the condition of multi-pore network, which distributes primarily as oil droplet, oil silk, detached island.

微观影响因素主要来自孔隙结构的非均质性、原油性质和注水压差，剩余油主要是在多孔隙网络体系条件下形成，其形态多以油珠、油丝、小油块和孤岛状分布。

Combined with sand-body distribution character, oil-bearing formation heterogeneity and oil water movement, strategy for increasing oil production has been put forward.
