Устройство для измерения количества и энергии гамма-лучей. Устройство состоит из кристалла и фотоэлектронный умножитель. В кристалле инцидент гамма придает энергию электронов через Комптона рассеяние, фотоэлектрического поглощения и производства пара. Электронов возбуждают детектор кристаллической решетки. Кристалл де возбуждения испускает видимым или вблизи видимый свет, Сцинтилляционный, который распознаётся фотоэлектронный умножитель и преобразован в электрический импульс. Частота и амплитуда электрического импульса связаны с количество гамма-лучей и их соответствующих уровней энергии и записываются в журнал. Сцинтилляционные детекторы используются во всех естественный гамма, индуцированных гамма-излучения и плотности устройств протоколирования.

A chemical treatment used to control or prevent scale deposition in the production conduit or completion system. Scale-inhibitor chemicals may be continuously injected through a downhole injection point in the completion, or periodic squeeze treatments may be undertaken to place the inhibitor in the reservoir matrix for subsequent commingling with produced fluids. <BR><BR>Some scale-inhibitor systems integrate scale inhibitors and fracture treatments into one step, which guarantees that the entire well is treated with scale inhibitor. In this type of treatment, a high-efficiency scale inhibitor is pumped into the matrix surrounding the fracture face during leakoff. It adsorbs to the matrix during pumping until the fracture begins to produce water. As water passes through the inhibitor-adsorbed zone, it dissolves sufficient inhibitor to prevent scale deposition. The inhibitor is better placed than in a conventional scale-inhibitor squeeze, which reduces the retreatment cost and improves production.

A cylindrical or spherical vessel used to separate oil, gas and water from the total fluid stream produced by a well. Separators can be either horizontal or vertical. <BR><BR>Separators can be classified into two-phase and three-phase separators (commonly called free-water knockout). The two-phase type deals only with oil and gas, while the three-phase type handles oil, water and gas. Additionally, separators can be categorized according to their operating pressure. Low-pressure units handle pressures of 10 to 180 psi (69 to 1241 kPa). Medium-pressure separators operate from 230 to 700 psi (1586 to 4826 kPa). High-pressure units handle pressures of 975 to 1500 psi (6722 to 10,342 kPa). <BR><BR>Gravity segregation is the main force that accomplishes the separation, which means the heaviest fluid settles to the bottom and the lightest fluid rises to the top. Additionally, inside the vessel, the degree of separation between gas and liquid will depend on the separator operating pressure, the residence time of the fluid mixture and the type of flow of the fluid. Turbulent flow allows more bubbles to escape than laminar flow.

A curve used to generate a certain type of fractal geometry. Straight lines are replaced by regular polygons repeatedly. These curves look like a snowflake when displayed graphically and are used to illustrate that a curve has a fractal dimension D>1.

A crack or surface of breakage within rock not related to foliation or cleavage in metamorphic rock along which there has been no movement. A fracture along which there has been displacement is a fault. When walls of a fracture have moved only normal to each other, the fracture is called a joint. Fractures can enhance permeability of rocks greatly by connecting pores together, and for that reason, fractures are induced mechanically in some reservoirs in order to boost hydrocarbon flow. <BR><BR>Fractures may also be referred to as 鈥渘atural fractures鈥?to distinguish them from fractures induced as part of a reservoir stimulation or drilling operation. In some shale reservoirs, natural fractures improve production by enhancing effective permeability. In other cases, natural fractures can complicate reservoir stimulation.
