Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to a gas separation and sand control device under pump, as shown in figure 1, including eye coupling 1, 2 one ends of 1 bottom threaded connection eye pipe of eye coupling, 2 this end inner wall welding of eye pipe have annular baffle 3 simultaneously, 4 one ends of 2 other end threaded connection on the eye pipe connect 4, 5 one ends of 4 other end threaded connection urceolus on the top connection, 5 other end threaded connection left-hand member joints down 9 of urceolus, 3 welding sectional type center tubes 6 one ends of annular baffle, 6 external diameters of sectional type center tubes and 3 internal diameter looks adaptations of annular baffle, 6 other end threaded connection feed liquor eye pipes 7 one end of sectional type center tubes, 6 include 2-3 center tubes of sectional type center tube, threaded connection in proper order, 6 outside welding spiral deflectors 8 of center tube sectional type. During construction operation, the lower joint 9 is connected with a sand setting tail pipe and is put into an oil well.
Preferably, the eye tube 2 and the liquid inlet eye tube 7 are uniformly provided with round holes.
The sectional type central pipe in the utility model is formed by connecting 2-3 sections of central pipes with the length of 1 meter through threads, so that the oil-gas separation time is increased, the effective separation of oil and gas is effectively ensured, and the central pipe can be rapidly installed and disassembled according to the actual condition of an oil well; meanwhile, gravity type and centrifugal type double separation are adopted, so that the gas separation capacity is strong; the copper gauze sand prevention at the liquid inlet end of the perforated pipe is combined with the internal rotary sand setting during gas separation, so that the sand prevention effect is outstanding; and the device has simple structure, easy processing and manufacturing, lower use cost and convenient popularization.
The utility model relates to a gas separation and sand control device under pump, its theory of operation as follows: during the use, according to the oil well actual conditions, select the sectional type center tube 6 of the variable length of suitable quantity to assemble, utilize lower clutch 9 to be connected with the sand setting tail pipe during workover, utilize eye coupling 1 to be connected with the oil-well pump and go into the oil well with the device in, when the oil well is normally opened and is taken out work, liquid mixture gets into the device from eye 2 and flows downwards in, flows to center tube feed liquor eye pipe 7 department through spiral water conservancy diversion piece 8 and gets into the center tube, later flows upwards under the suction effect of oil-well pump and gets into the oil-well pump, further lifts liquid to ground. In the process, gas is separated by a gravity type and centrifugal type double separation method, sand slides down along the inner side of the outer cylinder of the body and falls into a sand setting tail pipe by a rotary centrifugal method, the gas influence of an oil well pump and the sand clamp failure are effectively prevented, and the effects of improving the pump efficiency, saving the cost and reducing the consumption are achieved.
The utility model relates to a gas separation and sand control device under pump, its beneficial effect lies in: the device is installed under an oil well pump, the lower part of the device is connected with a sand setting tail pipe, when a liquid mixture enters the interior of the device through an eye tube during gas distribution, the liquid flow direction is horizontal, the liquid mixture and a central tube are impacted and disturbed, so that part of gas is separated from the liquid, bubbles move upwards under the action of gas-liquid density difference, the primary separation of oil and gas is realized, the liquid continues to move downwards in an inverted spiral mechanism, the disturbance is further intensified under the centrifugal action, the gas and the liquid are further separated, the bubbles slide upwards, and the bubbles slide away from the eye tube part of the central tube liquid inlet; during sand control, the liquid inlet end of the eye pipe of the device adopts the conventional copper gauze sand control measure at present, the liquid is spirally moved downwards by using a spiral mechanism inside the device to generate centrifugal force, and the sand is moved away from the outside of the central pipe by utilizing the density difference between the sand and the liquid and finally falls into a sand setting tail pipe. When in use, the device effectively avoids the underground faults of the oil well caused by gas influence and sand production, prolongs the pump inspection period of the oil well, and plays the roles of saving expenses and reducing consumption.
