In the process of oilfield development, water injection is a very important work content, and reservoir exploitation quality, efficiency, are closely related. Oilfield technology has been widely applied popularized, but in specific application, it will also have some influence on oilfield, such as causing oil layer blockage. The author focus application well injection, analyze related reasons f...

Past research has suggested that during the calving period, caribou (Rangifer tarandus) in Arctic Alaska generally avoid areas within 1 km of oilfield roads with traffic. However, avoidance is not absolute, and caribou may habituate to infrastructure (e.g., buildings, roads, well pads) and human activity. We conducted road-based surveys of caribou in oilfields on Alaska’s Arctic Coastal Plain d...

The composition of oilfield water is complex and diverse. development application corrosion inhibitors can effectively inhibit the pipelines equipment by water. ions in produced Jidong Oilfield were determined instrumental analysis chemical analysis. Triazine prepared from ethanolamine formaldehyde as inhibitor was evaluated weight loss method. inhibition experiments carried out ancient samples...

Subsidence in river deltas is a complex process that has both natural and human causes. Increasing human activities like aquaculture and petroleum extraction are affecting the Yellow River delta, and one consequence is subsidence. The purpose of this study is to measure the surface displacements in the Yellow River delta region and to investigate the corresponding subsidence source. In this pap...

The Bozhong oilfield (Hereinafter referred to as BZ oilfield) is a typical representative of complex fluvial reservoirs in the Bohai Sea, located southern with an average porosity 30.3% and permeability 643 × 10-3 μm2, belonging medium high reservoir, reservoir has good connectivity, underground crude oil viscosity 5 mPa·s. There are many plane fault blocks, longitudinal well section long, so o...

When an oilfield is developed with a polymer drive, the injected will play role in improving already formed dominant channel between oil and water wells, but after drive block transferred to subsequent development, inefficient circulation field of be wells again. This paper mainly applies dynamic static data, combined analysis adjustment optimization software high water-bearing oilfield, identi...

Two of the most fundamental concepts in the current debate about future oil supply are oilfield decline rates and depletion rates. These concepts are related, but not identical. This paper clarifies the definitions of these concepts, summarizes the underlying theory and empirically estimates decline and depletion rates for different categories of oilfield. A database of 880 post-peak fields is ...

Decision making pertaining to injection profiles during oilfield development is one of the most important factors that affect the oilfields’ performance. Since injection profiles are affected by multiple geological and development factors, it is difficult to model their complicated, non-linear relationships using conventional approaches. In this paper, two adaptivenetwork-based fuzzy inference ...

The compatibility of the dimensions polymer molecular aggregates and pore throat reservoir were studied. W section Tuha oilfield was study area polymers produced by Daqing Refining Chemical Company used. permeability limit molecules with different masses concentrations, matching relationship between dimension obtained experiments. results research are important for development implementation a ...
