In view of the problem that water cut rises quickly in conglomerate reservoirs with high cut, based on variation law reservoir injection and liquid production characteristics, a method for determining maximum scale is established by using engineering field statistics.Considering capacity at well end, end injecting-production ratio limit to keep formation energy, determine energy sufficient.This...

XX oilfield has a total of 10,561 oil and water wells, 6,790 wells were drilled in the oil-water layer, but only 10.3% so development degree same layer is relatively low. In stage cut stable production, geological reserves are considerable. Based on large number data statistics this paper understands developed situation characteristics plane vertical distribution, discusses feasibility to add p...

Because some oilfields in China belong to the thin bottom water reservoir model, actual drilling process is technically difficult. In order ensure maximum operation of target layer and basic development effect oilfield, technicians should introduce advanced steering tools study new geosteering technology fundamentally exploitation quality oil reservoirs.After exploring introduction geological g...

A study of the reservoir characteristics Tournaisian formation in Yablunivske oil and gas condensate filed shows that pore structure this area is complex permeability varies widely. Based on logging response characteristics, core analysis data curves GR, DT normal resistivity curves, mud content, porosity, permeability, bound water saturation parameters were calculated by statistical regression...

For the Tahe Oilfield, there are multiple sets of karst reservoirs with different genesis developed in carbonate fracture-vuggy and varying reservoir type has a considerable influence on distribution residual oil. The complex characteristics difficulty producing remaining oil middle lower part greatly restrict recovery effects. This work managed to comprehensively investigate action mechanism n...

This paper is devoted to the design of a distributed heterogeneous data warehouse digital oilfield. With increasing amounts collected from intelligent controllers and sensors, lack mechanisms for combining different sources providing them consumers affect overall management efficiency. In addition, without it impossible making next logical step – effective application analysis methods. The desc...

Environmental impact assessments for new Arctic infrastructure do not adequately consider the likely long-term cumulative effects of climate change and to landforms vegetation in areas with ice-rich permafrost, due part lack environmental studies that monitor changes after is built. This case study examines (1949–2020) climate- road-related a network ice-wedge polygons, Prudhoe Bay Oilfield, Al...

X oilfield is located in the Western Bohai Sea. During water injection development process, oil well productivity continued to decline. The effect of and increase poor. This time, by analyzing sensitivity reservoir, damage mode reservoir analyzed, reasons for poor are obtained, because strong sensitivity, medium stress corresponding measures suggestions put forward, such as greater than 4500 mg...

A firm owns the investment rights over one undeveloped oilfield with technical uncertainties on the size and quality of the reserve. In addition, the long run expected oil price follows a stochastic process. The firm needs to select the best alternative of investment in information with different costs and different revelation powers. The modeling of technical uncertainty uses the practical con...

Most onshore oil fields in China are the later stage of development, and water content is more than 90%, which increases difficulty remaining mining. In order to improve production, it necessary develop a variety recovery technologies, increase field space pressure, weaken viscosity, factor. Taking L oilfield as an example, paper briefly expounds characteristics extra-high cut period, on this b...
