Abstract:
对油藏属性参数变化规律及其变化机理的研究可为优化油气富集区的开发模式奠定基础。本文对比国内外计算相对渗透率方法并对油田开发过程中孔隙度和渗透率变化的影响因素进行研究得出:油田开发过程中孔隙度和渗透率变化的影响因素很多,包括裂缝的连通性、孔隙大小分布、注入水悬浮固体、注入水和地层水的不相容性、最佳注入速度,以及岩石类型和阻力等都是影响注水效果最重要的控制因素。针对国内水驱油田目前的开发状况,在计算相对渗透率过程中可以借鉴国外的做法,注重研究测量数据和计算方法之间的内在关系和匹配方式。
Study on reservoir parameters variation rules and characteristics provide fundament for develop-ment modes of optimizing remaining pay zone. This paper compares relative permeability calcula-tion methods domestic and overseas and studys influential factors of porosity and permeability var-iations during oilfield development, recognitions of this paper are concluded as follows: influential factors of porosity and permeability variations during oilfield development include factures conduc-tivity, pore scale and distribution, suspended solid of injected water, incompatibility of injected wa-ter and formation water, optimum injection rate, and rock types and resistance. According to the development status in domestic waterflood oilfields, when calculating relative permeability, foreign experience of focusing on correlation and match of measured data can be referred.

Ni―P―BNw化学复合镀层的组织与耐磨性

摩擦学学报 , 1998,
Abstract: 将TNT炸药爆炸石墨型六方氮化硼转化成的纤锌矿型密排六方氮化硼(BNw)微粉与Ni-P合金液相共沉积制备了Ni-P-BNw化学复合镀层.研究结果表明,Ni-P-BNw化学复合镀层具有比Ni-P化学镀层更小的胞状组织,BNw微粒未改变Ni-P的非晶态特征,但却降低了它的晶化温度,明显地提高了它的硬度和耐磨性,Ni-P-BNw复合镀层的磨损失效形式为磨粒磨损.
