低渗透率 meaning in Chinese
low permeability
Examples
- The main conclusion of research is that the formation of shihezi and shanxi in the upper palaeozoic gas pool at the sulige gas field is characteristic of low permeability and medium porosity
研究的主要结论：苏里格气田上古气藏下石盒子组-山西组的储层为低渗透率、低孔隙度储层，沉积相类型主要是河流沉积。 - 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。 - Aiming at some reservoir characteristics of low porosity , extra - low permeability , low oil saturation , and low productivity as well as shallow depth in changxi area of ansai oilfield , through a large number of laboratory experiments and field tests , some suitable fracturing technology and operation parameters have been optimized , including low temperature fracturing fluids . , propping fracture radius 、 pre - liquid and sand - fluid ratio
摘要针对安塞油田长西区低孔隙度、特低渗透率、低含油饱和度和浅层低产的油藏特性，通过大量室内、现场试验研究，优选出适合的压裂施工参数，包括低温压裂液、裂缝支撑半径、前置液和砂液比。 - Research section braided distributary channel sandstone is mostly positive rhythm , and high porosity and seepage rate in its central - top section , low seepage rate kalk interbed in its bottom . underwater distributary channel sandstone is relatively homogeneous positive rhythm , high porosity and seepage rate in its bottom , its top low . distributary mouth bar sandstone is complex rhythm , many interbeds inside
研究区宏观非均质性特点为：研究区辫状分流河道砂体以正韵律为主，高孔、渗带在砂体中上部，底部常存在低渗透率钙质夹层；水下分流河道砂体为较均质的正韵律，下部孔渗高，上部孔渗变小，分流河口坝砂体为复合韵律，砂体内部夹层多。
