天然裂缝 meaning in English
intrinsic fracture
natural fissure
natural fracture
natural split
Examples
- Bounded naturally fractured reservoir
封闭式天然裂缝性储层 - Natural fractures that distribute randomly in the reservoir arc different from the hydraulic fractures that connected with oil and water wells
摘要随机分布在储集层中的天然裂缝不同于与油水井相连通的人工裂缝，进行稳态产能方程研究时，在教学上用常规方法难以对其进行处理。 - The case study shows the reason that for low permeability reservoir , oil well and water injection well should be spaced where natural fractures are developed in order to reach helter production response
计算实例从理论上说明了低渗透油藏中，油水井部署在天然裂缝发育处开发效果较好的原因。 - The surface of natural fracture ( crack ) is parallel to the orientation of maximum principal stress . the principle orientation of anisotropic permeability reservoirs agrees with the orientation of the maximum principle stress . many engineering problems ( e . g . bore - hole stability , casing deformation failure during drilling , reasonable arrangement of wells , the optimum design of hydraulic fracture and so on ) are influenced by the in - situ stress orientation
天然裂缝面和裂隙面与最大主应力方向平行；在各向异性低渗透率油田中主渗透率方向与最大水平主应力方向趋向一致：在钻井过程中井壁稳定性，套管变形和损坏，油田开发井网合理布置、水力压裂优化设计等都与地应力方向有关。 - In order to well exploit the high - viscosity oil reservoirs , high - angle multilayer oil reservoirs , fractured oil reservoirs and thin - layer oil reservoirs , the oil reservoirs with gas cap and / or bottom water and the offshore oil and gas fields , the horizontal well techniques have been followed with interest by the people more and more
因此对于稠油油气藏、大倾角多层油气藏、天然裂缝油气藏、薄油层油气藏、具有气顶或者底水的油气藏以及海上油气田的开采，水平井技术越来越受到人们的关注。
