The drilling liquid-gas separator is arranged above the air hammer, and is capable of effectively removing water vapor and other impurities in air to ensure that air entering the air hammer is purified and further the abrasion of parts of the air hammer is reduced, thereby increasing the work efficiency of the air hammer.
Description
Technical field
The utility model relates to a kind of pneumatic hammer drilling well liquid-gas separator, belongs to oil/gas drilling downhole tool technical field.
Background technology
At present, pneumatic hammer drilling technology hard formation, low pressure and easy leaking stratum and high the grinding in stratum obtain comparatively extensive use, become petroleum exploration domain drilling speed, hold angle, prevent one of effective means that down-hole accident occurs; It is circulatory mediator that the pneumatic hammer drilling well has adopted inexhaustible air, can the contaminated oil gas-bearing formation.But, during the field, the stratum water outlet usually appears.Stratum water outlet meeting soaks water-sensitive shale, cause the well slough bit freezing, and wet landwaste sticks on drilling-rod external wall and to form the mud cake ring, can not be taken out of from annular space by air, effective solution is to inject continuously atomization base fluid or foam base fluid, be converted into atomization or foam drilling, to eliminate the mud cake ring, and take water, take sand and prevent cave-in, now, enter in the air of pneumatic hammer and often contain water and other impurity, accelerated the wearing and tearing of hammer body, reduced the operating efficiency of pneumatic hammer.
The utility model content
The utility model purpose is to provide a kind of pneumatic hammer drilling well liquid-gas separator, is arranged on the top of pneumatic hammer, can effectively remove steam and other impurity of containing in air, and the air that enters pneumatic hammer is purified.
For achieving the above object, the technical solution of the utility model is:
A kind of pneumatic hammer drilling well liquid-gas separator, by shell, rotary fluid, separator tube, plug, check valve, formed, shell is tubular body, undergauge hole and inner chamber are arranged in it, rotary fluid, separator tube and plug are arranged in inner chamber from top to bottom successively, rotary fluid is by the separator tube positioning supports, and separator tube bottom and plug are threaded connection fixing; Have radial direction through hole on the shell tube wall corresponding with plug, check valve is arranged in this radial direction through hole.
Adopt the taper surface transition between upper end, undergauge hole and screw thread.
Adopt the taper surface transition between lower end, undergauge hole and inner chamber.
Described rotary fluid is filled circles column structure, is evenly equipped with helicla flute on external cylindrical surface.
Described separator tube is the cylinder hollow structure, is evenly distributed in radial direction through hole.
Described plug is hollow structure, and upper end is tapered, and lower end is cylindrical tube, forms an annular gap between cone lower limb and shell.
Between the inner tubal wall of plug and shell, sealing ring is installed, the sealing ring is positioned at the check valve below.
The beneficial effects of the utility model are: the utility model is arranged on the top of pneumatic hammer, can effectively remove steam and other impurity of containing in air, the air that enters pneumatic hammer is purified, has reduced the wearing and tearing of pneumatic hammer parts, thereby improve the operating efficiency of pneumatic hammer.
The accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model.
In figure: 1-shell, 2-rotary fluid, 3-separator tube, 4-plug, 5-check valve, 6-sealing ring, 7-undergauge hole, 8-inner chamber, the top connection of 9-pneumatic hammer.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, the utility model is comprised of shell 1, rotary fluid 2, separator tube 3, plug 4, check valve 5.Shell 1 is tubular body, and undergauge hole 7 and inner chamber 8 are arranged in it, and rotary fluid 2, separator tube 3 and plug 4 are installed in inner chamber 8 from top to bottom successively, and rotary fluid 2 is by separator tube 3 positioning supports, and separator tube 3 bottoms and plug 4 are threaded connection fixing; Have radial direction through hole on shell 1 tube wall corresponding with plug 4, check valve 5 is installed in radial direction through hole.
Adopt the taper surface transition between 7 upper ends, undergauge hole and screw thread, can reduce the generation of fluid turbulence phenomenon.
Adopt the taper surface transition between 7 lower ends, undergauge hole and inner chamber 8, contribute to fluid to produce swirling motion.
Described rotary fluid 2 is filled circles column structure, is evenly equipped with helicla flute on external cylindrical surface.
Described separator tube 3 is the cylinder hollow structure, is evenly equipped with radial direction through hole on tube wall.
Described plug 4 is hollow structure, and upper end is tapered, and lower end is cylindrical tube, on the plug 4 position outer wall corresponding with the radial direction through hole on the shell tube wall, has endless groove, and endless groove contributes to store liquid.
During use, termination drilling tool on the utility model, lower end is arranged on the top of pneumatic hammer top connection 9, and pneumatic hammer top connection 9 is fixed rotary fluid 2, separator tube 3 and plug 4.During work, moisture and air-flows other impurity enter undergauge of the present utility model hole 7 from drilling tool, then enter rotary fluid 2, produce swirling motion at a high speed under helicla flute effect on rotary fluid 2 external cylindrical surfaces, under the effect of centrifugal force, be separated into lighter air and heavier liquid impurity, lighter air enters in the hollow channel of plug 4 along the through hole on separator tube 3 tube walls, and enters pneumatic hammer downwards, heavier liquid impurity moves downward in the position of departing from the shell center, cone apparent motion along shell 1 inwall and plug 4 tops enters annular gap, annular gap contributes to improve flow rate of liquid, when pressure reaches the opening pressure of check valve 5, check valve 5 is opened, check valve 5 also can stop annular fluid to enter inner chamber 8, prevent the suck-back phenomenon, heavier liquid impurity just can enter drilling tool and borehole wall annular space is discharged, thereby realize that liquid gas separates, the air that enters pneumatic hammer top connection 9 is purified, the wearing and tearing of pneumatic hammer parts have been reduced, thereby improve the operating efficiency of pneumatic hammer.
