Oil layer A of T oilfield has a low development degree. At present, there are 5 medium and highyield wells in the area, showing good evaluation prospect. In order to understand reserve potential this reservoir forming law characteristics further analyzed by analyzing structure characteristics. The research shows that two types reservoirs: one is structural reservoir, which distributed large tra...

The relative permeability curve is an important basic data for the preparation and dynamic analysis of oilfield development ( adjustment ) schemes. Due to different types curves in water cut stages, there a large deviation prediction indexes ultra-high stage according early development. In order study change process, based on morphological characteristics 118 28 coring wells Xingbei area after ...

Oilfield underground fracturing technology is an important oilfield development technology, through the injection of fluid to make rock fracture expansion, in order improve productivity oil reservoir. In this paper, selection and design fluid, tools devices, control parameters, evaluation fractures, adjustment optimization after are discussed. Through analysis these points, it can provide guida...

With the acceleration development of oilfield exploration and development, higher requirement for the precision of seismic interpretation is needed for that only higher accuracy of horizon calibration can match reservoir within the scope in the work area more effectively with full well to further lay a solid foundation of fine reservoir calibration which guarantee further fine structure interpr...

Water-soluble hydrophobically associating polymers are examined with particular emphasis on their rheology for oilfield applications. The incorporation of a small amount (less than 1 mol%) of hydrophobic groups into the polymer backbone of a water-soluble polymer dramatically alters the rheological properties of the resulting material. Associating polymers have potential for use in mobility con...

This paper applies Data Envelopment Analysis (DEA) and Elasticity Analysis to an empirical assessment study on innovation ability and innovation potentiality. According to inputs and outputs data of these innovative enterprises, we build CCR model, BCC model and Elasticity model to measure their innovation ability and innovation potentiality. The results show that innovation ability is varied b...

The levels of 16 polycyclic aromatic hydrocarbons (PAHs) were investigated in 27 upper layer (0-25 cm) soil samples collected from the Dagang Oilfield (China) in April 2013 to estimate their distribution, possible sources, and potential risks posed. The total concentrations of PAHs (∑PAHs) varied between 103.6 µg·kg(-1) and 5872 µg·kg(-1), with a mean concentration of 919.8 µg·kg(-1); increased...
