Abstract
The utility model relates to a kind of pipe string of oil-water well leakage tester, while belonging to oil well repairing operation, OIH pipe, sleeve pipe is tested to pressure test tool technical field leakage.Formed by body, baffle plate, valve ball, sliding sleeve, body is the tubular body that upper and lower two ends are provided with connecting thread, the bottom of body tube wall has flowing hole, in the tube wall on flowing hole top, by shear pin, sliding sleeve is installed, in the tube wall of flowing hole bottom, be provided with interior gear platform, the internal diameter of interior gear platform is less than the external diameter of sliding sleeve; On the upper surface of sliding sleeve, valve ball is installed, in the body tube wall on valve ball top, by screw thread, baffle plate is installed, on baffle plate, have inlet opening.The beneficial effects of the utility model are the main body inner chambers that valve ball are placed on to baffle plate and sliding sleeve formation, by suppressing, the oil pipe in well, sleeve pipe are carried out to disposable testing leakage, change the form of construction work of former pitching pressure testing, solve packer and look for the problem that in process leakage, flow chart is many, success rate is low, saved operating cost.
Description
Technical field
The utility model relates to a kind of pipe string of oil-water well leakage tester, while belonging to oil well repairing operation, the oil pipe in well, sleeve pipe is tested to pressure test tool technical field leakage.
Background technology
Along with going deep into of oil field development, the problems such as oil-water well cover damages, cover becomes, cover leakage are on the rise, and have restricted the enforcement of every oil production technology, therefore utilize packer to look for Lou construction technology quantity to increase to sleeve pipe.At present to look for Lou technique be by rotation seat sealed type packer to conventional packer and constant-pressure sliding sleeve is supporting looks for leakage, because pitching is not in place or when the leakage of the above oil pipe of packer, capital causes sliding sleeve not open, cause the whole cover Tube-colume for seanching leakage area failure of testing, success rate is lower, increase operating worker labour intensity, waste operating cost.
The patent No. 200920028286.9 discloses a kind of casing leakage-finding decompression tool, it by packer, pressure release body, cut off pin, sliding sleeve, seal and form, sliding sleeve upper end endoporus has horn mouth, the steel ball of being convenient to and drop into forms sealing, stops up the endoporus of sliding sleeve, look for Lou complete after when pressure release, sliding sleeve can be opened, liquid in oil pipe flow in sleeve pipe, but looks for leakage to lose due to top tubing string leakage or not in place easily the causing of pitching, increases operating cost.
Summary of the invention
The purpose of this utility model is in order to overcome the above-mentioned checking Tube-colume for seanching leakage area sealing that lacks of the prior art, the defect that operation is done over again easily to occur, and provides the one can test tube column sealing, can implement again packer and look for integrated down-hole leakage tester leakage.
The utility model is made up of body, baffle plate, valve ball, sliding sleeve, body is the tubular body that upper and lower two ends are provided with connecting thread, the bottom of body tube wall has flowing hole, in the tube wall on the top of the flowing hole on body tube wall, by shear pin, sliding sleeve is installed, in the tube wall of the bottom of the flowing hole on body tube wall, be provided with interior gear platform, the internal diameter of interior gear platform is less than the external diameter of sliding sleeve; On the upper surface of sliding sleeve, valve ball is installed, in the body tube wall on valve ball top, by screw thread, baffle plate is installed, on baffle plate, have inlet opening.
The beneficial effects of the utility model are the main body inner chambers that valve ball are placed on to baffle plate and sliding sleeve formation, by suppressing to realize, the oil pipe in well, sleeve pipe are carried out to disposable testing leakage, change the form of construction work of original pitching pressure testing, solve packer and look for the problem that in process leakage, flow chart is many, success rate is low, saved operating cost.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, the utility model is made up of body 1, baffle plate 3, valve ball 4, sliding sleeve 6, body 1 is the tubular body that upper and lower two ends are provided with connecting thread, the bottom of body 1 tube wall has flowing hole 8, in the tube wall on the top of the flowing hole 8 on body 1 tube wall, by shear pin 7, sliding sleeve 6 is installed, is provided with interior gear platform 9 in the tube wall of the bottom of the flowing hole 8 on body 1 tube wall, the internal diameter of interior gear platform 9 is less than the external diameter of sliding sleeve 6; Valve ball 4 is installed on the upper surface of sliding sleeve 6, in body 1 tube wall on valve ball 4 tops, by screw thread, baffle plate 3 is installed, on baffle plate 3, have inlet opening 2.
Described sliding sleeve 6 upper ends are pyramidal structure, on the bonding surface of sliding sleeve 6 and body 1, " O " shape sealing ring 5 are installed.
On described baffle plate 3, be evenly equipped with 3 or 4 inlet openings 2.
Described body 1 bottom is evenly equipped with 3 or 4 flowing holes 8.
In the time that oil-water well needs packer to look for Lou because of hole condition problem, top connection of the present utility model is connected with top oil pipe by screw thread, under connect rotation seat sealed type packer, ball seat is lowered to after design attitude, the suitable height of upper lifting pipe post, rotate setting, suppress from oil pipe, working fluid presses down valve ball by the inlet opening 2 on baffle plate 3, common sealing function at valve ball 4 with sliding sleeve 6 cone match and O-ring seals 5, running string is carried out to pressure testing, after inspection oil pipe is qualified, continue to suppress, when pressure reaches shear pin 7 value for shear of design, sliding sleeve 6 is descending, drop in the tube wall of body 1 bottom and be provided with interior gear platform 9 places, working fluid enters oil jacket annular space through flowing hole 8, production string more than packer is looked for leakage, ensure to test pipe, look for the disposable of Lou construction, reduce construction cost.
