Abstract Herringbone wells are effective in improving productivity for bottom water reservoirs; however, the main problem faced exploitation of reservoir is ridge and cone during process waterflooding, which leads to decline oil production. Therefore, predicting breakthrough time location herringbone reservoirs then adjusting injection measures great significance production development. In this paper, we establish a three-dimensional coning model study dynamic performance rise, sequence...
Herringbone wells are of great significance in tapping the potential remaining reservoirs, improving recovery efficiency, and reducing development costs have been widely used oilfields, especially offshore oilfields. Due to complex structure herringbone wells, there is mutual interference between wellbores during seepage, resulting seepage problems, it difficult analyze productivity evaluate perforating effect. In this paper, considering branches perforations, a prediction model transient...
In the process of heavy oil exploitation, formation temperature changes severely, which will cause deformation skeleton and redistribution permeability, then affect crude seepage. On contrary, change permeability distribution field. order to study relationship between in a reservoir, on basis three field coupling mechanisms, authors adopted physical simulation experiment effect results show: when is kept at same level, sample decreases with increase effective stress, decline rate bigger...
Abstract With the characteristics of large drainage area and low drilling cost, herringbone wells have become an important way to increase well production, delay coning ridge bottom water improve development effect. Due complexity flow characteristics, results that exists certain gap between current production prediction actual so it is great significance study productivity wells. In this paper, taking bottom-water reservoir as research object, considering interference branch wellbore...
After many years of mining in the Fang2 block Songfangtun oilfield, conventional water drive development method can no longer meet requirement greatly improving recovery rate, and ternary composite (TCD) technology is adopted for this purpose. TCD one most important methods to further improve crude oil recovery, it has entered industrialization promotion stage, but there are still problems fouling injection extraction system high production maintenance costs. In order reduce formation damage...
摘要： 为分析轮轨非稳态载荷与钢轨疲劳裂纹萌生的关系，利用有限元法建立二维轮轨非稳态循环滚动接触有限元模型。非稳态以移动法向载荷随时间简谐变化实现，采用考虑棘轮效应的JIANG-SEHITOGLU循环塑性本构模型，计算不同轮轨循环接触状态下的残余应力、应变场，结合多轴疲劳损伤模型，分析钢轨疲劳启裂寿命、位置和方向。计算结果表明，轮轨非稳态循环滚动会引起钢轨接触表面波浪形塑性变形，其波长与载荷压力波长一致。随着循环滚动次数累加，残余应力和剪切应变在钢轨表面变形的波峰和波谷处逐渐增大，并在滚动次数达到40次后趋于稳定，且在波谷处大于波峰处；在钢轨表层产生的轴向残余应力大于纵向。轮轨蠕滑率对钢轨轴向和纵向残余应力影响较小，对残余剪切应变影响较大。车轮单次滚动过于低估残余应力应变和疲劳寿命；考虑车轮循环滚动时，轮轨接触斑全滑动时的钢轨启裂寿命为纯滚动时的4.5倍；波谷位置处的钢轨启裂寿命为波峰位置处的1.4倍。
