Description
Technical field
The present invention relates to oil field equipment, especially a kind of steam injection string of oil-field thick-oil steam injection oil recovery by heating horizontal well.
Background technology
Horizontal well technology starts from the eighties in 20th century, is mainly used in ligh-oil reservoir and gas reservoir, it is advantageous that to improve oil gas well yield and recovery ratio.Along with the continuous progress of horizontal well technology, the application scale of horizontal well constantly increases, and the Oil Reservoir Types of application is more and more extensive, and so far, industrial applications is in Development of Viscous Crude Oil and cbm development.
For the horizontal well development of heavy crude reservoir, mainly be that the application level well carries out steam soak, steam flooding and SAGD (SAGD).Because the oil reservoir area of horizontal well contact is far longer than straight well, thus horizontal well steam injection heating oil reservoir and reduce the wider of Crude viscosity, the moveable oil area is larger, and the output of oil well is higher.But general steam injection mode is adopted at present horizontal well steam injection usually, for heterogeneous reservoir, because varying level section reservoir permeability differs greatly, it is uneven to cause horizontal segment to inhale vapour, in the continuous steam injection process, at the bottom of the steam that injects from horizontal well is advanced by leaps and bounds producing well along the local high permeable strip of horizontal segment easily, cause early stage vapour to alter, seriously reduced the development effectiveness of horizontal segment development degree and horizontal well.
A kind of horizontal well sectional steam injection pipe column of prior art is on the horizontal instlated tubular of screen casing rear side, from front to back successively tandem stabilizers, obstructing instrument, centralizer and distributor.Its beneficial effect is that the steam under the input well is all entered in the steam injection oil reservoir of setting, in steam injection process, only have one section well casing relative with the steam injection oil reservoir position of setting to be in the hot environment, so that the well casing elongation is less, can not cause well head to destroy.Its weak point is: the one, be lowered to the segmentation steam injection string after, can only be simultaneously a section of horizontal well be carried out steam injection, can not so just reduce the suction vapour length of horizontal segment to full horizontal segment while steam injection, reduce drainage area and the producing well production capacity of unit interval; The 2nd, after the steam injection of a certain specific steam injection section finishes, in the time of need to carrying out steam injection to another section, the user need to pull out steam injection string by external pull outside well, therefore changing the steam injection section need to relate to very complicated work-over operation, and steam injection section of the every replacing of steam injection well all needs closing well.
