Abstract
An oil-water well sand washing tool is characterized in that a valve seat is processed inside a nipple-shaped outer casing 1, the valve seat is equipped with an oblique angle valve 3 with the tubular wall processed with through holes, and a spring 4 is sleeved on the outer wall of the oblique angle valve 3. The oil-water well sand washing tool is simple in structure, convenient in mounting and reliable in operation, can resolve the problem of blowout control inside an oil string when used for oil-water well backcycling sand washing construction, and can not only avoid overflow of the oil string and well explosion but also bring convenience for site operation and avoid environmental pollution.
Description
Technical field:
The utility model relates to a kind of oil field downhole tool, especially for a kind of oil-water well sand flushing tool of underground work.
Technical background:
Before the utility model; each oil field is for improving oil-water well sand washing construction effect; the inverse circular sand washing adapter modes that adopt more; but, rising, down during the tubing string operation, can't use single current valve in the direct circulation sand washing mode oil pipe commonly used because this mode limits by technological process; solve the problem of blowout prevention in the tubing string; thereby through regular meeting's generation tubing string overflow or gas blowout accident, not only make troubles to site operation, also may pollute environment.
Summary of the invention:
The purpose of this utility model is: for oilfield oil well sand washing construction provides a kind of oil-water well sand flushing tool, because this device has increased by spring controlled oblique sharp valve, can solve, the following problem of blowout prevention during the tubing string operation, thereby can avoid the generation of tubing string overflow or gas blowout accident, not only make things convenient for site operation, also can avoid pollution on the environment.
The purpose of this utility model realizes by following measure: a kind of oil-water well sand flushing tool, comprise shell, back-up ring, spring, cushion rubber, it is characterized in that: the middle part is equipped with the back-up ring of annular in the screwed short tubular shell in upper end, and is processed with obconic valve seat; The top is installed on the valve seat to be inverted cone, middle part and to be the oblique sharp valve that short tube shape, lower end are inclined point shape; Be processed with on the tube wall of oblique sharp valve middle part and be processed with shoulder on open-work, the outer wall and be set with spring, between oblique sharp valve outer wall and the outer casing inner wall cushion rubber is installed also.
The utility model is simple in structure, easy for installation, reliable operation, can solve the problem of blowout prevention in the tubing string when being used for oil-water well sand washing construction, not only can avoid the generation of tubing string overflow or gas blowout accident, make things convenient for site operation, also can avoid pollution on the environment.
Description of drawings:
Fig. 1 is an oil-water well sand flushing tool structural representation.
The specific embodiment:
The oil-water well sand flushing tool is to be made of shell 1, back-up ring 2, oblique sharp valve 3, spring 4, cushion rubber 5 etc.The middle part is equipped with the back-up ring 2 of annular in the screwed short tubular shell 1 in upper end, and is processed with obconic valve seat; The top is installed on the valve seat in the shell 1 is inverted cone, middle part and is the oblique sharp valve 3 that cylinder, lower end are inclined point shape, be processed with shoulder and be set with spring 4 on the oblique sharp valve 3 middle part outer walls, between oblique sharp valve 3 outer walls and shell 1 inwall cushion rubber 5 is installed also.
The operating principle and the using method of oil-water well sand flushing tool are: the screw thread by shell 1 upper end is connected to sand washing tubing string bottom with this device earlier, when, time tubing string operation, owing to be subjected to the effect of spring 4, oblique sharp valve 3 is seated on the valve seat in the shell 1, and with the shutoff of tubing string internal channel, thereby realized the interior blowout prevention of tubing string; When following the sand washing operation as need are counter, the sand washing tubing string can be transferred, and the oblique point of oblique sharp valve 3 lower ends is contacted with down-hole sand face, this moment is under the effect of tubing string gravity, the power that oblique sharp valve 3 can overcome spring 4 is moved on relatively, and open the interior passage of tubing string, working solution then can enter in the tubing string by the open-work on oblique sharp valve 3 tube walls, has carried out normal sand washing operation.
