Description
Technical field
The utility model relates to fluid and electric mixed connection device between a kind of drill collar.
Background technology
Because with boring in the formation tester, bore ship and will carry out fluid (pressure oil, oil return, formation fluid etc.) and be electrically connected between the ship with boring, the fluid that bores between the ship is with boring one of key technology that formation tester develops with being electrically connected.Electric the mixing with fluid between existing two kinds of pipe nipples is connected, and generally will rotatablely move by Rapid-turning nut becomes rectilinear motion, realizes by spininess plug and fluid connecting tube.Yet in the measuring while drilling instrument, rely between two brill ships and bore the connection of ship special screw thread, middle without Rapid-turning nut.Therefore can not realize boring being connected of fluid and electric mixing between ship.
The utility model content
What the technical problems to be solved in the utility model provided a kind of dependable performance, working stability is used to bore fluid and the electric syndeton of mixing between ship.
In order to address the above problem, the utility model provides fluid and electric mixed connection structure between a kind of drill collar, comprising:
The fluid passage, described fluid passage comprises that connection respectively is arranged on first passage group and the second channel group on drill collar male and the drill collar female, link to each other by ring shaped slot between described first passage group and the second channel group, be provided with sealing ring between described any ring shaped slot;
Electrical connector, described electrical connector comprise that the position is arranged on the first joint group and the second joint group that matches on described drill collar male and the drill collar female accordingly respectively, and at least one set of joints is the annulus setting in the described first joint group and the second joint group.
Further, described fluid passage is 3.
Further, the described first joint group and the second joint group center tap are the annulus setting.
Further, described electrical connector is 12.
Further, between described drill collar male and the drill collar female by being threaded.
The utlity model has following advantage:
1, adopt ring shaped slot to be connected in the utility model in the fluid passage between first passage group and the second channel group, no matter how radial position can both realize the connection of fluid passage when axially putting in place, in the electrical connector in the first joint group and the second joint group arbitrary set of joints be the circumference setting, no matter how radial position can both realize electric reliable connection when axially putting in place, make when drill collar male and drill collar female are linked and packed, can make things convenient for, realize reliably fluid and electric multichannel conducting.
2, the utility model is simple in structure, realization is safe and reliable, and the utility model applicability is wide, is convenient to standardization and makes, and helps promoting the use of.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 shows fluid and electric mixed connection structure sectional structure schematic diagram between a kind of drill collar of the utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises fluid passage 1 and electrical connector 2.When drill collar male 3 and drill collar female 4 were linked and packed, the conducting of fluid between pipe nipple was realized in fluid passage 1, and electrical connector 2 is realized electric conducting between pipe nipple.
Fluid passage 1 comprises first passage group 11 and second channel group 12, first passage group 11 is arranged on the drill collar male 3, second channel group 12 is provided with on the drill collar female 4, be interconnected between first passage group 11 and the second channel group 12, thereby when drill collar male 3 is linked and packed with drill collar female 4, between pipe nipple, form the passage that fluid is communicated with.
Link to each other by ring shaped slot 13 between first passage group 11 and the second channel group 12, all link to each other between ring shaped slot 13 and first passage group 11 and the second channel group 12 by connecting hole 14, because ring shaped slot 13 is an annulus, can make first passage group 11 and second channel group 12 when drill collar male 3 and drill collar female 4 are linked and packed, no matter as long as how the radial position that axially puts in place all can be communicated with.
Arbitrarily be provided with sealing Figure 15 between the ring shaped slot 13, sealing Figure 15 can make positiver sealing between the ring shaped slot 13, thereby realizes the sealing between each fluid passage 1.
Electrical connector 2 comprises that the first joint group 21 and the second joint group, 22, the first joint groups 21 are arranged on the drill collar male 3, and the second joint group 22 is arranged on the drill collar female 4.The first joint group 21 and the second joint group 22 match, and the position correspondence on drill collar male 3 and drill collar female 4.
At least one set of joints is the annulus setting in the first joint group 21 and the second joint group 22.Because in the first joint group 21 and the second joint group 22 set of joints being arranged is the annulus setting, can make when drill collar male 3 and drill collar female 4 are linked and packed, the back radial position how no matter axially put in place, each joint all can reliably be connected conducting in the first joint group 21 and the second joint group 22, realizes electric conducting between pipe nipple.
Adopt ring shaped slot 13 to be connected in the utility model in the fluid passage 1 between first passage group 11 and the second channel group 12, no matter how radial position can both realize the connection of fluid passage 1 when axially putting in place, in the electrical connector 2 in the first joint group 21 and the second joint group 22 arbitrary set of joints be the circumference setting, no matter how radial position can both realize electric reliable connection when axially putting in place, make when drill collar male 3 and drill collar female 4 are linked and packed, can make things convenient for, realize reliably fluid and electric multichannel conducting.
In the utility model, fluid passage 1 is 3.This fluid passage 1 is respectively hydraulic oil oil inlet passage, hydraulic oil drainback passage and slurry channel.
In the utility model, the first joint group 21 and the second joint group, 22 center taps are the annulus setting.Two set of joints are the annulus setting, the connection between convenient each joint, and more easily processing.
In the utility model, electrical connector 2 is 12.Electrical connector more than 2 groups are communicated with simultaneously, have reduced connecting link, can increase work efficiency.
In the utility model, between drill collar male 3 and the drill collar female 4 by being threaded.Because the utility model for the radially requirement of assembling, can not adopt to be threaded.Employing is threaded simply, reliable, also can realize sealing function by the screw thread own characteristic.
The utility model is simple in structure, realization is safe and reliable, and the utility model applicability is wide, is convenient to standardization and makes, and helps promoting the use of.
In sum; it below only is preferable case study on implementation of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
