Sensornets promise to extend automated monitoring and control into industrial processes. In spite of great progress made in sensornet design, deployment and operational cost impedes use of sensornet in many real-word scenarios—these challenges are so great that industries often continue with infrequent, manual observations over automation, even for key business processes. In this paper we propo...

It is important to program properly during process of oilfield development. Based on the fuzzy understanding about the reservoir and the uncertainty in the actual environment, a kind of fuzzy multi-objective optimization model of production distribution was proposed in this paper, which considers the objectives of production maximization, cost minimization and profit maximization. By using the ...

Bozhong A Oilfield is located in the northeast of Huanghekou Sag Bohai Bay Basin, and a complex fault block oilfield. The main oil bearing horizon lower Minghuazhen Member, belonging to shallow water delta sedimentation. For rolling exploration evaluation adjacent blocks, this paper uses mudstone smear method analyze accurately characterize lithological contact relationship between two walls fa...

Bohai A Oilfield is the first fluvial facies oilfield in Sea to be developed using a horizontal well layering system. It has characteristics of thin single sand reservoir thickness, large differences reserve scale, rapid lateral changes reservoirs, and staggered stacking multiple river channel bodies vertical direction. In production, it characterized by decline ground pressure, increase water ...

Due to the complexity of low-permeability reservoirs, there is no set established plans adjust development specific and final adjustment plan should be determined through comprehensive consideration many aspects. At present, reservoirs in SN oilfield faces problems. It urgent formulate corresponding improve current situation. In view problems surface oilfield, this paper used previous research ...

Due to the long-term development of water and gas injection in Tahe Oilfield, production increase effect decreases year by year. Based on understanding treatment difficulties stage fractured vuggy reservoir this paper combined with theoretical analysis Nano-sheet technology at stage, such as super amphiphilic interface performance, emulsification viscosity reduction ability, ultra-low core adso...

Abstract In oilfield, scaling caused by water injection is becoming increasingly serious blocking the gathering and transmission pipelines of oilfield resulting in a decline production great loss production. Oil gas leakage pipeline scaling, corrosion perforation has irreversible damage to surrounding environment. this paper, citric acid sodium pyrophosphate are used as main agents, hydrolytic ...
