Soybean, which is rich in protein and oil, is cultivated in several climatic zones; however, its growth is markedly decreased by flooding. Proteomics is a useful tool for understanding the flooding-response mechanism in soybean. Subcellular proteomics has the potential to elucidate localized cellular responses and investigate communications among subcellular components during plant growth and d...

Abstract With the maturity of fault-block reservoirs, water percolation channels are formed after long-term waterflooding, which leads to large amounts remaining oil unrecovered and low recovery efficiency. Thus, it is imperative seek for enhancing methods improve development performance mature reservoirs. Well pattern adjustment heterogeneous phase combined flooding both feasible technologies ...

China’s economy is in an important period of rapid development, the rise various industries to produce a greater demand for oil, oil exploitation industry has become focus whole society. The vast majority fields China have entered polymer flooding development stage, and reservoir been effectively improved. subsequent water can make further excavated, which key technology recent years. This pape...

The high water cut stage is an important of the injection development oilfields because there are still more oil reserves available for recovery in this stage. Most have experienced decades waterflooding and adjustment. Although reservoirs face problems seriously watered-out highly dispersed distribution remaining oil, they remain dominant waterflood development. This paper investigates current...

We consider the problem of displacement processes in a three-layer fluid in a Hele-Shaw cell modeling enhanced oil recovery processes by polymer flooding. The middle layer sandwiched between water and oil contains polymer-thickened-water. We provide lower bounds on the length of the intermediate layer and on the amount of polymer in the middle layer for stabilizing the leading front to a specif...

Forced displacement of oil by polymer flooding in oil reservoir is one of the effective methods of enhanced (tertiary) oil recovery. A classical model of this process within Hele-Shaw approximation involves three-layer fluid in a Hele-Shaw cell having a variable viscosity fluid in the intermediate layer between oil and water. The goal here is to find an optimal viscosity profile of the intermed...

Abstract Due to the long-term scouring of steam/water flooding, water channels restricts expansion streamlines in swept region. The formation main streamline, an inevitable and troublesome challenge during restrict spread sweep region oil extraction reservoirs. To realize adjustment (SA), well pattern (WPA) polymer flooding (PF) are mature technologies applied development reservoir. WAF PF, as ...
