Description
Technical field
the utility model relates to oil field oil, gas well down-hole sand-proof tool, specifically a kind of multilayer variable orifice sand screen.
Background technology
it is one of major issue of running in recovery process of oil that current oil field oil, gas well shake out.Can not get effective improvement if shaked out, oil, gas well shake out will be more and more serious, causes oil, gas well can not get effective exploitation.Traditional anti-sand method mainly contains following several: one is mechanical type sand control; Two is chemical formula sand controls; Three is combined type sand controls.What the sand output well of Shengli Oil Field more than 90% adopted is mechanical type sand control, and mechanical type sand control is divided into again two large classes; One is the sand block of pre-fill sand prevention tubing string, two be under enter sand control pipe and carry out filling again.There is following problem in above-mentioned sand control: one is antidetonation, anti-falls ability; Two is that crush resistance strength is low; Three is that effective drainage area is little, and flow resistance is large, can not meet oil field oil, gas well liquid loading needs.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of multilayer variable orifice sand screen.
the utility model is realized by following technical proposals:
the utility model comprises: top connection, baffle plate, central tube, filter sand body, protective screening.The threaded upper ends of the central tube of described multilayer variable orifice sand screen is connected to top connection, lower end is provided with external screw thread, and central tube main body is provided with flowing hole, is provided with filter sand body outside flowing hole, filter sand is external is provided with protective screening, is provided with baffle plate at the top of filter sand body top perimeter, protective screening.
baffle plate cross section in above-mentioned multilayer variable orifice sand screen is trapezoidal circulus.
to be that resin and sand are cementing form the mix cylinder with certain hole to filter sand body in above-mentioned multilayer variable orifice sand screen.
protective screening in above-mentioned multilayer variable orifice sand screen is 1 ~ 5 layer.
the beneficial effects of the utility model are: be applicable to oil field oil, gas well sand control has following characteristics:
1. degree of porosity more much higher layer variable orifice sand screen is more suitable for and builds oil, the high efficiency passage in gas well underground;
2. reduce local and pierce through risk.Under equal conditions, speed when higher degree of porosity makes the speed of underground fluid when infiltrating comparatively infiltrate other sand control installation wants slow many, so just avoids sand grains local under larger hydraulic pressure to pierce through risk;
3. resin sand control filtration beds, sand control reliability is high;
4. filter area is large, and flow resistance is little, and crude oil, output are high.
filter opening is stablized, and non-deformability is strong, meets horizontal well and high angle hole instructions for use;
6. surperficial resistance to erosion, can adapt to the well-flushing in various situation;
7. length-flexible, can match according to different hole conditions;
8. long service life, extends the sand control cycle, saves operating cost;
9. anti-layer of sand is not easily blocked by less gravel, keeps high permeability for a long time;
10. construction operation is easy to operate, and operating cost is low.
Accompanying drawing explanation
fig. 1-the utility model master is depending on partly cuing open structural representation.
in figure, 0. flowing hole, 1. top connection, 2. baffle plate, 3. central tube, 4. filter sand body, 5. protective screening.
Detailed description of the invention
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
multilayer variable orifice sand screen is made up of top connection 1, baffle plate 2, central tube 3, filter sand body 4, protective screening 5.The threaded upper ends of the central tube 3 of described multilayer variable orifice sand screen is connected to top connection 1, lower end is provided with external screw thread, central tube 3 main body is provided with flowing hole 0, resin sand filter sand body 4 is provided with outside flowing hole 0, be provided with 4 layers of protective screening 5 outside filter sand body 4, being provided with cross section at the top of filter sand body 4 top perimeter, protective screening 5 is trapezoidal ring-shaped baffle 2.
method of operating
1. press designing requirement sand washing when oil, gas well operation to certain depth, sand setting pocket is not less than 20m;
2. check sleeve with the drift size gauge tool of dimension, meet the smooth G.I.H of multilayer variable orifice sand screen;
3. tubing string connects from bottom to top: plug (or temperature-sensing valve)+sand setting oil pipe+centralizer+multilayer variable orifice sand screen+centralizer+oil pipe+packer+oil pipe is to well head;
by multilayer variable orifice sand screen down between oil reservoir Lower and upper bounds, error
+1m, grappling setting by packer requirement, gives up, and running speed is less than 30 pieces/hour, at the uniform velocity transfers and forbids percussion drill, drilling string not well braked.
