Description
Technical field:
The utility model relates to sidetracked casing windowing technology field, stratum, a kind of buried hill, particularly the continuous window opening tool in stratum, a kind of reducing type buried hill.
Background technology:
Windowing milling wimble is the milling tool of windowing for CST, its advantage windows that speed is fast, window is smooth, round and smooth, not easily form dead step, be the common tool that current CST is windowed.Existing buried hill high pour point oil reservoir reservoir is granite hard formation, and development cost is high.Run into a series of stern challenge in on-the-spot application, such as, high abrasive granite hard stratum casing windowing milling cone serious wear, quantity consumed are large, often need 3 ~ 5 millings cones just can complete construction of windowing, and the process efficiency that causes windowing is low.For this technical problem, we have carried out the research of hard stratum casing windowing Sidetracking Technology, take first to descend small size milling to bore and beat neck eye, more lower large scale milling are bored reaming, are windowed.Strengthen optimizing research from aspects such as tool construction, material and technological parameters, achieve outstanding progress, achieve the maximization drilling depth of reservoir.But the milling cone that this technique changes owing to frequently making a trip the size that varies in size, although achieve certain effect, really to extend drilling period for cost.
Utility model content:
The technical problems to be solved in the utility model is to provide the continuous window opening tool in stratum, a kind of reducing type buried hill, the arrangement achieves for buried hill high abrasive granite hard stratum casing windowing, there is the effect of playing neck eye, reaming and having bored for a time, improve work efficiency 3 ~ 5 times, cutting power is strong, drilling depth is fast, can reach stratum, single instrument complete independently buried hill to window work, integral structure design has higher tension, torsional strength.Overcome existing buried hill high abrasive granite hard stratum casing windowing and need the milling cone changing the size that varies in size that frequently makes a trip, the deficiency that drilling period is long.
Technical solution adopted in the utility model is: the continuous window opening tool in stratum, a kind of reducing type buried hill, comprises main body; Main body is column, body head is spherical, on this spherical, heap is welded with YD5-8 particle carbide electrode, main body back segment diameter is greater than leading portion, main body back segment is connected with leading portion transition, main body leading portion, changeover portion and back segment external surface angularly weld many YG8 rectangular block carbide alloy, and main body leading portion, changeover portion and back segment external surface angularly weld many YG8 eight prism carbide alloy, and main body leading portion, changeover portion and back segment external surface angularly weld many YD5-8 particle carbide electrodes.
The YD5-8 particle carbide electrode thickness >=25mm of built-up welding on body head spherical.
The beneficial effects of the utility model are: the utility model is owing to have employed reducing type integral structure, thus for buried hill high abrasive granite hard stratum casing windowing, there is the function of playing neck eye, reaming and having bored for a time, improve work efficiency 3 ~ 5 times, cutting power is strong, drilling depth is fast, can reach stratum, single instrument complete independently buried hill to window work, integral structure design has higher tension, torsional strength.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, the continuous window opening tool in stratum, a kind of reducing type buried hill, comprises main body 1; Main body 1 is column, and main body 1 head is spherical, and on this spherical, heap is welded with the thickness >=25mm of YD5-8 particle carbide electrode 4, YD5-8 particle carbide electrode 4.Main body 1 back segment diameter is greater than leading portion, main body 1 back segment is connected with leading portion transition, main body 1 leading portion, changeover portion and back segment external surface angularly weld many YG8 rectangular block carbide alloy 2, main body 1 leading portion, changeover portion and back segment external surface angularly weld many YG8 eight prism carbide alloy 3, and main body 1 leading portion, changeover portion and back segment external surface angularly weld many YD5-8 particle carbide electrodes 4.
When the utility model uses, front end small size beats neck eye, and rear end large scale reaming, can bear the moment of torsion identical with drilling tool in construction.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
