Abstract
The utility model relates to a downhole tool for the hole expanding construction process of a petroleum drilling well, in particular to a side drilling well. The downhole tool comprises an upper joint, a body, a stabber edge, water holes, diamond compounding pieces, a spiral water passage and alloy pieces, wherein the upper end of the body is provided with the joint, the outer side of the lower part of the body is provided with the stabber edge, the front end of the stabber edge is inlaid with the aluminium alloy pieces, the inner side of the body is inlaid with the diamond compounding pieces, and the lower part of the body is provided with the spiral water passage in an angle of 60 degrees and a plurality of water holes. The tractive tool has reasonable design, novel structure and reliable operation and can satisfy the requirements of different types of wells to smoothly guide a hole expander into the well and avoid downhole troubles. Because the tractive device can smoothly pass through drilling fluid and improve the state of the drilling fluid, and consequently, the work efficiency of the hole expanding operation can be increased.
Description
Technical field:
The utility model relates to a kind of particularly downhole tool of sidetracked hole reaming hole work progress of oil drilling that is used for.
Background technology:
Along with the development of oil drilling, development technology in oilfield technology, sidetracked hole is used scale and is increased day by day.According to oil gas well sidetracked hole construction operation rules, creep into to the design well depth in bore hole, adopt off-balance bit or reamer to carry out reaming hole.In recent years, off-balance bit and reamer are used in sidetracked hole reaming hole operation reality year by year to be increased, and obtains good effect.But, isostructuralism problem that the conventional reaming hole drafting tool that uses is unreasonable owing to the water channel design at present, diameter is excessive, rigidity is not enough, down-hole accidents such as mud drum, bit freezing often take place in drilling well reaming hole process, influence carrying out smoothly of work progress, and the safety of work progress is constituted a threat to.
The utility model content:
The utility model purpose is to provide a kind of drilling liquid flow that can improve in the construction of drilling well reaming hole through form, improve the drilling well reaming hole drafting tool of lowering velocity and the safety of reaming hole work progress greatly.
The utility model purpose is to realize like this.This kind tractor is made up of top connection, body, awl sword, hydrophthalmia, diamond compact, spiral channel and aluminum alloy sheet, its structure assembled relation is as follows: the body upper end is provided with top connection, the outside, bottom is provided with the awl sword, and awl sword front end studs with aluminum alloy sheet, and the inboard is inlaid with diamond compact; The body bottom is provided with spiral channel and a plurality of hydrophthalmia that is 60 degree angles.During use, the joint of this drafting tool by its upper end is connected with reamer and G.I.H thereupon, can carries out the reaming hole operation.Because the outside is inlaid with diamond compact and aluminium alloy compound sheet respectively in the awl sword of body bottom, thereby makes the tough and tensile degree of awl sword be improved, and can not only effectively improve the speed of passing through that reamer is transferred process, can also suitably repair the borehole wall.Spiral channel and a plurality of hydrophthalmia that the body bottom is provided with then can be guaranteed passing through smoothly of drilling fluid, avoid the generation of down hole problems such as mud drum and bit freezing, thereby improve the safety and the operating efficiency of reaming hole operation.
The utility model is reasonable in design, novel structure, reliable operation, utilize it can satisfy the requirement of different well types, play the effect that reamer is gone into the well smoothly and avoided down-hole accident that imports, because this pulling equipment can pass through drilling fluid smoothly, improves drilling fluid state, thereby can improve the operating efficiency of reaming hole operation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the hydrophthalmia distribution schematic diagram.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of top connection 1, body 2, awl sword 3, hydrophthalmia 4, diamond compact 5, spiral channel 6 and aluminum alloy sheet 7.Wherein, body 2 adopts the material of high temperature high voltage resistant, and its upper end is provided with the joint of button in the band, and it is conical that the bottom is, lower end band arc surface, and its outside is provided with 60 degree spiral channels, and is evenly equipped with 6 hydrophthalmia (see figure 2)s on same cross section.
