Description
Technical field
The utility model belongs to Oilfield Natural Gas Plant note, adopts the blowout control equipment technical field of well high pressure, well logging with pressure, particularly relates to a kind of natural gas filling, adopts well wireline logging high-tension blowout-prevention system.
Background technology
Oilfield Natural Gas Plant is noted, is adopted well high pressure, wireline logging Technics of Prevention of Well Blowout with pressure, it is a current new logging technique, natural gas filling is adopted well test data and is had effective application, adopts the storage change of rear stratum, whether down-hole pollutes, side-wall begriming, note sampled-current amount etc. test parameter has permanently effective application effect to note.It is complicated that natural gas filling adopts well shaft mouth test Technics of Prevention of Well Blowout, natural gas well note is adopted in process, due to natural gas gas flammability, high flow rate, note sampled-current amount large (200 cubic meters per day), note mining height pressure, toxic and harmful, factor that environment pollution and northeastward summer in the winter temperature difference are large etc. restriction, existing wireline logging Technics of Prevention of Well Blowout, blowout preventer equipment cannot solve current natural gas gas storage well, fuel gas note mining height pressure in process of production, note mining height flow velocity, note adopts large discharge, produce the slight seepage of wireline logging blowout hookup, electrostatic and logger meet card, the accident such as to rush to summit is in the measure of quick closedown wellhead sealing device.
Domesticly at present have developed wireline test well mouth sealing device, solve the well mouth sealing device of high pressure well, high pressure thin oil well and low pressure gas-producing well (pressure is not higher than 5MPa), the method implements sealing to well head, the wellhead sealing method of current employing be have three grades or more levels and cable outer triumphant match metal choke tube, extruding cushion rubber through cable seal, well mouth sealing device upper end must be equipped with overflow line and be carried out overflow.When Problems existing is wireline test, can not seal completely even if main flow pipe injects stop-leak compound, along with the outer steel of variations in temperature main flow pipe inwall and cable triumphant between gap increase frictional resistance reduced, high pressure, high flow rate, the speed overflow of high flow capacity gas wink, metal choke tube, it is uncontrollable that cushion rubber wearing and tearing will strengthen seepage, air-flow and cable remove and easily produce frictional static, in addition without the complete well head safe precautionary measures, as well logging logger is rushed to summit, card met by instrument, well head above wireline test well mouth sealing device has seepage uncontrollable, the also more incomplete natural gas well high pressure well logging spraying-preventing system with pressure with autonomous property right.Therefore a kind of new natural gas filling is provided, adopts well wireline logging high pressure (well logging with pressure) spraying-preventing system to overcome the above problems.
(1) natural gas has inflammable, explosive, easy to leak, the feature such as colourless, tasteless, and have special requirement to well mouth sealing device, shaft mouth anti-blowout pipe, blowout prevention box must possess the measure such as antistatic, movable sealing.Natural gas has dissolubility and diluting effect to noted movable sealing fat in a high voltage state, and its sealing difficulty is strengthened further.If containing H in gas
2poisonous or the etchant gas such as S, relevant device must possess anti-sulphur performance, otherwise all can will constitute a serious threat to equipment and human body.
(2) construction risk of logging well is large.Due to high pressure, high flow rate, high flow capacity wellhead blowout preventer bear extreme working position, and facility reliability is restricted, and well head pressure is high, easily cause the out of control and gas blowout accident of well head.Whole work progress carries out under must ensureing complete air-tight state, and well head can not occur overflow phenomena, once there is overflow, is easy to cause cable and preventer to freeze, produce the engineering accident of electrostatic.
(3) well head pressure is high, and downhole instrument string is long, and wellhead blowout preventer is placed in work high above the ground, forms directly threaten ground installation and GCU.
(4) particularly well note/gas production normal every day is noted/adopted in gas storage storehouse all more than 1,000,000 sides, far beyond conventional gas well yield scope.
(5) blowout control equipment is by the impact of gases at high pressure, and sealing ring is easy to be corroded, and sealing difficulty is large, and equipment and technology and performance indications require corresponding high.
Above 5 kinds is all the key issues needing to solve.
