| 1. | Numerical model of compound influencing factor on coal reservoir permeability 煤储层渗透率复合因素数值模型研究 |
| 2. | Compress experiment of coal cleat and mathematical simulation of coal reservoir permeability 铁法矿区煤储层裂隙系统评价与渗透率预测研究 |
| 3. | Estimation of the reservoir permeability using the frequency offset and time lag of stoneley wave 利用斯通利波的频率偏移和时间延迟判断储层渗透性 |
| 4. | Some of the production wells in jianghan oil region possess the geological features including low reservoir permeability , thin adjoining layer between water and oil layers , etc 摘要江汉油区部分油井具有油层渗透率低、油水层之间隔层薄等地质特点。 |
| 5. | In the process of waterflooding , the injected water will contact inevitably with the rock and fluid in reservoirs and various physical and chemi cai actions will happen , causing thus the reservoir permeability to go bad and the formation to be damaged 但注水过程中,注入水必然要与储层岩石、流体接触,并发生各种物理化学作用,从而导致储层渗透率恶化,使地层受到伤害。 |
| 6. | Meanwhile , its negative influences under the reservoir conditions should be recognized such as influence of microorganism on reservoir permeability , influence of the products of microorganism on formation plug , influence of iron sulfides precipitation and biochemical affection of microorganism 研究认为,油藏条件下微生物也有其负面影响,如菌体对储集层渗透率的影响、微生物的生成物引起地层堵塞、硫化铁的影响、微生物的生化作用等。 |
