Abstract
The utility model relates to a composite sand-preventing perforated well completion device for an oil and gas well. The utility model organically combines two performing operations of perforation and sand prevention of a sand flowing oil and gas well together, and procedures of the performing operations of the perforation and the sand prevention are simplified. The utility model comprises a low-debris perforating bullet and a front barn. A shell of an annular container (5) which is made of friable material is served as sand-preventing material, and an energetic flexible explosive membrane and a gun powder ring which are driven in one side direction are placed in a ring cavity outside the container. The perforating bullet is detonated to generate jet streams, on one hand, the jet streams thread out a pore canal in yielding layers of the oil and gas well, and on the other hand, the jet streams drive energetic material to detonate in the side direction; in this way, under the pressure of charging the perforating bullet and driving the energetic material to detonate products in the side direction, sand-preventing material is pushed to the jet streams which carry the sand-preventing material into the pore canal threaded out by the jet streams, and an integrated sand-preventing filter stopper is formed in the pore canal. Rock liquid can pass through the filter stopper, and the filter stopper can effectively block stratum sand from flowing out. When the utility model is applied, capitals can be saved, the efficiency of the performing operations can be enhanced, and workover periods can be extended.
Description
(1) technical field:
The utility model belongs to a kind of oil gas well composite sand prevention perforation completion device of finishing perforation and one-level sand control simultaneously.
(2) background technology:
In the oil and gas exploitation process, shaking out is the problem of a commonplace existence, and shaking out has many harm, must be prevented.At present, anti-sand method will have arch sand control, and mechanical means and chemical sand control etc. are because these methods have a lot of deficiencies, as complex process, investment is big, the well workover cycle is short etc.So people were at the anti-sand method of actively seeking other in the last few years, as sand control perforating bullet with preceding storehouse, owing to utilize perforating bullet powder charge detonation product or shock wave etc. to make side direction contain material " igniting ", and then sand prevention material be filled into the duct very much by high pressure and the negative of jet generation that this energetic material produces.In fact this " igniting " mode is untimely and insecure, be later than the action time of jet the action time of energetic material, the result has only the sand prevention material of small part to be filled into the duct, and all the other sand prevention materials or stay in the preceding storehouse, or be scattering between perforating gun and the sleeve pipe, thereby do not satisfy the sand control requirement.The problem that installs that has sand prevention material because sand prevention material is a discrete particles, must be installed during use, if be solidified into ring with curing compound, then solidification intensity is difficult to control, the too high filling that influences sand prevention material of intensity, and intensity is too low also easily broken and cause some accidents.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem of depositing in the background technology, and provides a kind of with perforation and two operations of sand control organically combine and sand controlling result is good oil gas well composite sand prevention perforation completion device.
The invention for solving the technical problem can reach by following technical solution: the locating ring that the located perforating bullet is arranged on the Hatch Opening in preceding storehouse, lining is housed in the storehouse, the room shell made from fragile material and central duct is arranged is set, filling stainless steel wire group and the irregular shape particle of high strength cerioid in the room shell in it; Around the room shell is the chamber, filling flexible explosive film and gunpowder ring in the chamber.
In such scheme, can adopt low-chip perforating bullet.The profile of stainless steel group is that diameter is Φ 2mm～8mm, highly is 2mm～8mm cylinder, and wherein the stainless steel wire diameter is Φ 0.02mm～0.3mm.This composite sand prevention perforation completion device is by low-chip perforating bullet and place the preceding storehouse two parts in perforating bullet the place ahead to form, and connects and the location with locating ring between perforating bullet and the preceding storehouse.Setting side is to driving energetic material, sand prevention material and proppant in the preceding storehouse, side direction drives energetic material and is made up of flexible explosive film and fast-burning powder ring, sand prevention material is a stainless steel wire group, proppant is the irregular shape particle of high strength cerioid, and stainless steel wire group and proppant are contained in the annular container made from fragile material.Putting in order of each assembly is in the preceding storehouse, and ecto-entad is flexible explosive film, fast-burning powder ring, annular container and interior stainless steel wire group (containing proppant) thereof successively.Preceding storehouse inner surface is a rotary body, and the axis of other all component is all coaxial with preceding storehouse, and the axis is a fluidic channel.The flexible explosive film is close to preceding storehouse inwall, and the blocking-up fluidic channel in case jet it is ignited when passing.On the mechanism of action be: perforating bullet detonation produces jet, jet passes the duct on the one hand in the payzone of oil gas well, when penetrating the flexible explosive film, this medicine film is ignited on the other hand, afterwards again by the flexible explosive film fast-burning powder ring that ignites, like this, drive under the pressure of energetic material detonation product in perforating bullet powder charge and side direction, stainless steel wire group is pushed to jet.Bring stainless steel wire group in duct that jet passes by jet.Stainless steel wire group flows in the process in duct at carried as side-arm, because the draw of jet, also because silk group enters duct pressure abrupt release effect afterwards, each stainless steel wire group is drawn back or bulk opening, and collude with twining compacted together again, form the sand control filtering plug of an integral body, realize the purpose of sand control.
The utility model is compared with background technology has following beneficial effect: adopt jet to ignite the flexible explosive film, again by the medicine film gunpowder ring that ignites.So just overcome the shortcoming of the low delayed action of gunpowder combustion speed, the time that makes stainless steel wire group shift to jet shifts to an earlier date, and speeds up.Because this design can be mated the action time of gunpowder and the action time of jet better mutually, and is more compact on action time.
The utility model clearly proposes to bring stainless steel wire group in duct with jet.And do not form effective sand control filtering plug by the stainless steel wire group that other approach (as storehouse inner high voltage and energetic material promotion etc.) enters the duct.Because silk group has only by jet action, just can break its original structure, it is drawn back or bulk opening, and collude with twining compacted together again, form the sand control filtering plug of an integral body.The stainless steel wire briquetting is contained in the toroidal container of being made by fragile material, has solved the problem that installs of silk group.Fragile material is pressed into tiny fragment in powder charge detonation process, even becomes powder.The inner surface in preceding storehouse is the smoothed curve rotary body, its external structure is designed to the three-dimensional localization structure, be that adjacent two storehouses are adjacent to and fixing mutually---limit it and move axially and the relatively rotating of two storehouses, the perforating gun inwall is pressed close in preceding storehouse diametrically---and limit it and move radially.Avoided disturbing between bullet by such design, the course of conveying that has guaranteed sand prevention material is to finish in the preceding storehouse of separate and fixed-site.
