Нефтяная или газовая скважина - это

Нефтяная или газовая скважина - это приблизительно цилиндрическое сооружение в глубь Земли, включающее преимущественно вертикальную или наклонную горную выработку в непродуктивной зоне пород и соединенную с ней выработку любой направленности в продуктивной зоне горных пород, крепь в виде обсадных труб и цементных оболочек и фильтр, обеспечивающий надежную гидродинамическую связь скважины с продуктивным пластом. Основными элементами скважин
являются: устье, забой, ствол, обсадная колонна, фильтр, цементное кольцо.
Устье - это начало скважины, образованное короткой вертикальной зацементированной трубой - направлением.
Забой - это дно ствола скважины.
Ствол - это горная выработка, внутри которой располагаются обсад¬ные колонны и производится углубление скважины.
Обсадная колонна - это свинченные друг с другом и опущенные в ствол обсадные трубы с целью изоляции слагающих ствол горных пород. Различают первую обсадную колонну - кондуктор, последнюю обсадную колонну - эксплуатационную колонну, в том числе хвостовик, промежуточные обсадные колонны, в том числе летучки (лайнеры).
Фильтр - участок скважины, непосредственно соприкасающийся с продуктивным нефтяным или газовым горизонтом. Фильтром может служить необсаженный колонной участок ствола, специальное устройство с отверстиями, заполненное гравием и песком, часть эксплуатационной колонны или хвостовика с отверстиями или щелями.
Цементное кольцо - затвердевший цементный раствор, закачанный в кольцевое пространство между стволом и обсадной колонной с целью его герметизации.
Система обсадных колонн и цементных колец за ними составляют крепь скважины.
Только сооруженная скважина может ответить на вопрос: имеется ли в данном районе нефтяное или газовое месторождение и какова промышленная ценность залежи УВ

Oil or gas well is approximately cylindrical structure deep into the Earth, which includes predominantly vertical or sloping mountain development in non-productive zone rocks and connected to the production of any direction in the productive zone rocks, support in the form of casing and cement casing and filter ensures reliable hydrodynamic link well with the productive layer. The main elements of wells are: the mouth, face, trunk, casing, filter the cement ring.The mouth is the beginning of a well formed by short vertical zacementirovannoj pipe-line.Culling is the bottom of the hole.The barrel is working, inside of which are the obsad of data columns and the deepening of wells.Casing is screwed together and dipped into the barrel casing to isolate components a barrel of rocks. There are the first casing-jig, the last casing-maintenance column, including shank, the intermediate casing, including quizzes (liners).Filter-plot hole, directly facing the productive oil or gas horizon. Filter neobsažennyj can serve as a plot device, a special barrel with holes filled with gravel and sand, part of the production casing or liner with holes or slits.The cement ring-hardened cement mortal, uploaded in the annular space between the casing and the seal.The system casing and cement rings behind them are the supports of the well.Only built well can answer the question: does this area of an oil or gas field and the industrial value of HC deposits

Oil or gas well - is approximately cylindrical structure in the interior of the Earth, containing predominantly vertical or inclined mine workings in the area of non-productive breeds and connected with her ​​production of any orientation in the pay zone rocks lining in the form of casing and cement membranes and filter providing reliable hydrodynamic bond well with the reservoir. The main elements of the wells
are: the mouth, face, trunk, casing, filter, cement ring.
The mouth - this is the beginning of the well formed by a short vertical pipe cemented - direction.
Slaughter - it's the bottom of the borehole.
The barrel - this excavation within which the obsad ¬nye column recess and produced wellbore.
Casing - is screwed together and lowered into the barrel of the casing with the purpose of forming the insulation barrel rocks. Distinguish first casing - the conductor, the last casing - production string, including a shank, intermediate casing strings, including flying detachment (liners).
Filter - section of the well, in direct contact with oil or gas productive horizon. May serve as a filter column openhole trunk portion, a special device with holes filled with sand and gravel portion of production casing or liner with holes or slits.
Cementitious ring - hardened grout pumped into the annulus between the barrel and the casing with a view to sealing.
System casing and cement rings them up lining the well.
Only well construction can answer the question: is there in the area of an oil or gas field and what the industrial value of deposits HC

Oil or gas well drilling is approximately cylindrical construction to the interior of Earth,Which includes predominantly vertical or tilted mountain develop in an unproductive area rocks and connected to it develop any focus on the productive zone rocks,Shift in the form of a casing pipes and cement sheaths and filter that provides a reliable ect link wells with productive two cutlets. The main elements of wells
are: mouth, stocking, barrel,Casing, and the column filter, cement ring.
Mouth - this is the beginning of a wells, educated a short vertical зацементированнои tube - focus.
stocking - this is the bottom of the barrel bore wells.
a Barrel - this is a mountain,Within which are located обсад¬industrial tower and is deepening wells.
casing tower - this свинченные with each other and are countersunk in barrel roadbed with a view to isolating refractory barrel rocks.There are first string annulus is - the jig, the last string annulus is - operational tower, including shank, and the intermediate column casings, including летучки (Pec) .
Filter - area wells,Directly metal sensing proximity switch mounted at the productive oil or gas horizon. Filter can serve as a необсаженныи column area barrel, a special device with holes, filled by gravel and sand, whichPart of operational towers or shank with the holes or slits.
cement ring - hardened cement solution,Recurring query in the ring space between the stem and bandage grandeur, with a view to its sealing.
the system casing string and cement rings for them are shift wells.
Only produce well can answer the question: is there in the area oil or gas and what is industrial value deposits recoverable
