Abstract
The utility model relates to a horizontal well turbine sand removal device which comprises a lengthened coupling (1), a main shaft (2), a stabilizing sleeve (3) and the like, and is characterized in that the left end of the main shaft (2) is the oil pipe thread lengthened coupling (1), the round stabilizing sleeve (3) is fixedly arranged in the middle of the main shaft (2) in a sheathed or a welded way, the outer diameter of the stabilizing sleeve (3) is greater than that of a turbine (4), and the stabilizing sleeve (3) is axially provided with a plurality of through holes which are flow passages. The right end of the main shaft (2) is connected with the turbine (4) and a rotating head (7), two ends of the turbine (4) are fixedly installed by a bearing (5), and the gap is adjusted by a locking nut (6). The conical netty rotating head (7) is fixed at the front end surface of the turbine (4) in a welded way and is driven to rotate by the turbine (4). The horizontal well turbine sand removal device can improve the sand removal effect in a mineshaft, and injection of surfactant for soaking is not needed before construction, therefore, pollution to the stratum and the environment is avoided. The construction time is shortened, the sand washing liquid quantity is reduced, and the construction cost is saved.
Description
Technical field
The utility model relates to sand flushing device in a kind of well, particularly a kind of horizontal well turbine fettling installation.
Background technology
In the stratum of loose sand oil accumulation, poor diagenetic grade, loose cementation, the cement shale content is high, even existing at present various anti-sand methods, but for various reasons, be impossible in the aboveground sand production in oil of avoiding fully of oil gas.After the sand production in oil; When if the wellbore fluids rate of climb is not enough to that silt particle brought to ground,, form sand plug in the pit shaft on the one hand in pit shaft just silt particle can precipitate; Increase fluid flow resistance; On the other hand, because the existence meeting of silt particle causes severe impairment to pumping unit, even cause the pumping unit operational failure.Therefore for recovering the operate as normal of sand well, the silt particle that is deposited in the pit shaft is removed in operation that something must be done to.
The sand removal technology that use in present oil field is the direct circulation sand washing; Need to inject surfactant before the construction; Silt particle to being deposited in pit shaft soaks, and injects fluid through oil pipe to the shaft bottom then, breaks up sand plug at a high speed; Liquid by returning on the oil jacket annular space brings to ground with sand grains, to remove the problem of oil-water well sand plug.Along with the Application and Development of horizontal well, sand washing circulation canal sectional area limits, and direct circulation sand washing process shortcoming appears suddenly out; Because oil jacket annular space captured area is greater than the captured area in washing pipe hole, it is slow that the flow upward velocity becomes, in the pit shaft of horizontal well long well section; The sand cleaning fluid prop-carrying capacity is poor, silt particle deposition once more under the gravity of self, only some silt particle along with on the liquid that returns return out ground; Sand washing is not thorough, and construction effect is undesirable.
Summary of the invention
According to the technical problem of above-mentioned proposition, the utility model provides a kind of horizontal well turbine fettling installation of removing sand plug, recovering the oil gas water well ordinary production, is made up of lengthening box cupling (1), main shaft (2), supporting positive cover (3), turbine (4), bearing (5), locking nut (6), spinning roller head (7); It is characterized in that the left end at main shaft is a tubing round thread lengthening box cupling; Lengthening has a fluid course of 45 ° of having tilted on the box cupling, and the centre of main shaft is a supporting positive cover, and supporting positive cover adopts the mode of suit and welding to be fixedly mounted on the main shaft; Supporting positive cover is the circle shape; The external diameter of supporting positive cover is greater than the turbine external diameter, and a plurality of through holes that axially have of supporting positive cover are fluid course, and the right-hand member of main shaft connects turbine and swivel head; The two ends of turbine are installed by bearing fixing; Regulate the gap of turbine and swivel head with locking nut, the swivel head of the netted shape of circular cone is fixed by welding in the front end face of turbine, by the turbine driven rotary.
The beneficial effect of the utility model is: in horizontal well, straight well, inclined shaft workover treatment process; Use the utility model to carry out construction operation; The silt particle that is deposited in the pit shaft is cleaned out ground, recover the ordinary production of oil gas well, can improve silt particle cleaning performance in the pit shaft.Do not soak owing to need not inject surfactant before the construction, so stratum and environment are not constituted pollution.Shorten the construction operation time, reduced the sand washing liquid measure, practiced thrift construction cost.
Description of drawings
Fig. 1 is the front view of the utility model.
The specific embodiment
At left end of this device main shaft (2) tubing round thread lengthening box cupling (1) is installed, a fluid course of 45 ° of having tilted is arranged, on the lengthening box cupling (1) as uninterrupted circulation canal.Install supporting positive cover (3) in the center fixed of main shaft (2); The external diameter of supporting positive cover (3) is greater than turbine (4) external diameter; A plurality of through holes that axially have of supporting positive cover (3) are fluid course; Neither influence flow and pass through, the rigidity in keeping again gathering, service tube-column gravity does not restrict in not receiving when supporting tubing string weight for oral administration and turbine (4) rotation in guaranteeing to gather.The right-hand member of main shaft (2) connects turbine (4) and swivel head (7), and turbine (4) two ends are fixedly mounted by bearing (5), and regulates the gap with locking nut (6), guarantees the flexible rotation of turbine under water impact (4).Swivel head (7) is fixed by welding in the front end of turbine (4), by turbine (4) driven rotary.This device is connected service tube-column front end in the sand washing, down to the anti-sand removal operation that circulates of rumble seat.Turbine (4) and swivel head (7) rotate under water impact, and the silt that stirs deposition is mud soup, and service tube-column is returned out in getting into; Because interior service tube-column captured area is little; Inlet pressure and outlet pressure are keeping balance again in the construction, so flow velocity is fast, it is strong to take sand power performance.Silt particle can not precipitate last returning in the process once more, thereby reaches desirable sand washing effect.
