Description
Technical field
The present invention relates to the oil field development sand control screen, particularly a kind of high strength is annotated the vapour thermal recovery screen casing of handling up.
Background technology
Existing sand screen mainly contains wrapping wire and screen mesh type sand-screen, though these two kinds of screen casings can be used for sand control, but the shortcoming and defect of existing: 1. wire-wrapped screen can not be independent stops reservoir sand, gravel pack need be carried out and just the sand control effect can be played, behind the aboveground huff and puff oil recovery through 2 rounds of 1 ∽ of injection thermal recovery, filling bed is damaged easily and causes sand control to lose efficacy after the gravel pack; 2. wire-wrapped screen sand-preventing process complexity and success rate are low; Though 3. the screen mesh type sand-screen can directly stop reservoir sand, but its filtration beds is a flexible structure, and anti-extrusion ability is low; 4. the screen mesh type sand screen is because the filtration beds erosion resistibility is low, easily it washed out in steam oil production technology and causes sand control to lose efficacy; 5. its structure of screen mesh type sand screen is that several layers of silk screen easily stop up, and influences oil well output; 6. the parent tube flowing hole of sand screen adopts alternately boring of five equilibrium, and intensity reduces after processing, and is easily broken.
Summary of the invention
The purpose of this invention is to provide a kind of high strength steam injection thermal recovery screen casing, adopt the combining structure that secondary filter layer, spiral filtration beds and coarse filtration layer are installed on the parent tube, this screen casing can stop reservoir sand separately, can supporting gravel pack carry out sand control again, and be particularly suitable for that sand control uses the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art on the thermal production well that the steam injection of many rounds handles up.
High strength steam injection thermal recovery screen casing of the present invention comprises box cupling, centralizer, parent tube, weld-ring, secondary filter layer, spiral filtration beds, coarse filtration layer.One end of described parent tube is connected and installed with box cupling and centralizer, and the other end is provided with connecting thread, to satisfy the requirement of different-thickness oil reservoir duct length.Secondary filter layer, spiral filtration beds and coarse filtration layer from inside to outside are installed on the parent tube in turn.Be in the same place by weld-ring and parent tube sealing and fixing in the both ends of secondary filter layer, spiral filtration beds and coarse filtration layer.
Wherein, described secondary filter layer, spiral filtration beds and coarse filtration layer two ends are by weld-ring and the welding of parent tube sealing and fixing.Described weld-ring is the taper sleeve type fixing structure that contracts, and the outer end of weld-ring is installed and is connected with tapered sleeve, welds together with parent tube.The position that secondary filter layer, spiral filtration beds and coarse filtration layer are installed on the described parent tube is evenly equipped with the spiral flowing hole.Described secondary filter layer is to arrange the structure that inner protective layer, water conservancy diversion net, screen pack, the second water conservancy diversion net and second screen pack are installed from inside to outside.Described centralizer is the drum type sped structure, is evenly equipped with multi-head spiral groove on its cylindrical.The inner protective layer of described secondary filter layer be provided with water conservancy diversion to inner process.Big outer little trapezoidal shape structure in the slit of described spiral filtration beds is.Described coarse filtration layer 7 surface are provided with the rectangular bridge type effluent groove that evenly gathers.
The present invention has following advantage and beneficial effect compared with prior art:
1, the spiral filtration beds adopts stainless steel trapezoidal wire welded construction, has high strength and anti-extrusion performance, and more traditional sand screen intensity improves 25%, and has self-cleaning ability;
2, adopt classified filtering, reservoir sand can form effective filling bed after by classified filtering around screen casing, thereby improves strainability, improves filtering accuracy;
3, filtration beds is selected austenite heat-resistance stainless steel steel plate and steel wire for use, production, processing technology through the advanced person are made, and improve corrosion-resistant, erosion resistibility effectively, through test, the period of validity of oil well in periodicity steam oil production art production process, more traditional sand screen prolongs more than 3 times;
4, the coarse filtration laminar surface is provided with rectangular bridge type hole, and pass is rectangular trapezoidal latasuture, has avoided the dash damage of overcurrent liquid to the secondary filter layer, and has had certain self-cleaning ability;
5, parent tube adopts high-quality P110H sleeve pipe, and its flowing hole is the staggered cloth hole of single head spiral, has reduced parent tube intensity reduction after processing;
6, merge the advantage of wrapping wire sand screen and net formula sand screen, both had the gravel pack performance of wrapping wire sand screen, had the performance of the direct sand block of net formula sand screen again;
7, compliance is strong, can satisfy the various completion production practice of straight well, inclined shaft, the horizontal well requirement of ligh-oil reservoir and heavy crude reservoir, and oil-sand is effectively separated, and is suitable for horizontal well steam injection thermal recovery technology especially;
8, advanced design, rational in infrastructure, technology is advanced, all is better than the anti-sandpipe of tradition through testing various performance technologies indexs.
