Abstract
The present invention relates to coring with exempting from ball pitching tool in oil and gas well drilling power tool field.It includes return connector 7 and the bleeder 6 being arranged on return connector 7, hollow body 3 is connected in one end of return connector 7, piston 1 and spring 2 are set in body 3, the bottom connection traffic righting disc 4 of body 3, the periphery of flow righting disc 4 is provided with metering orifice 5, wherein piston 1 is sealed with the open top of body 3 and coordinated, and spring 2 is located between piston 1 and flow righting disc 4.The advantage of the invention is that：One is that tool construction is simple, when contained spring fails, changes parts simple；Two be safe and reliable, without worrying that dismantling drilling rod input steel ball produces potential safety hazard.
Description
Technical field
Exempt from ball pitching tool the present invention relates to used during underground work in oil and gas well drilling power tool field, belong to a kind of drilling and coring delivery instrument.
Background technology
During hard formation coring operation, circulation of drilling fluid is carried out before coring operation, drilling fluid is circulated by coring inner drum；After circulation terminates, steel ball is put into, changes drilling fluid runner, drilling fluid is flowed through return connector and inner/outer tube annular space of coring.Traditional stuff is above to carry drilling tool, sit extension, dismantles drilling rod, and steel ball is put into from drilling rod.But so pitching has the shortcomings that very big, especially can encounter following problem in gas well：1st, check-valves can be broken during check-valves, steel ball drop due to having inside drilling tool, cause has channeling；2nd, during steel ball drop, drilling tool inwall can be collided, spark is produced and sets off an explosion.
The content of the invention
It is to core to provide a kind of simple in construction, safe and reliable core with exempting from ball pitching tool in gas well it is an object of the invention to solve the potential safety hazard that pitching in gas well is produced.
To achieve these goals, the present invention takes following technical scheme：
One kind is cored with exempting from ball pitching tool, including return connector 7 and the bleeder 6 being arranged on return connector 7, hollow body 3 is connected in one end of return connector 7, piston 1 and spring 2 are set in body 3, the bottom connection traffic righting disc 4 of body 3, the periphery of flow righting disc 4 is provided with metering orifice 5, and wherein piston 1 is sealed with the open top of body 3 and coordinated, and spring 2 is located between piston 1 and flow righting disc 4.
Such scheme further comprises：
The body 3 assumes a " convex " shape structure, and its ledge is connected with the internal thread of return connector 7.
The tapered structure of piston 1, the open top of body 3 that cooperation is sealed therewith is the conical surface of same gradient.
The quantity of metering orifice 5 of bleeder 6 and the periphery of flow righting disc 4 on return connector 7 is 3-8；Flow righting disc 4 is connected by screw thread with body 3.
The working mechanism of the present invention：Spring and piston are assembled in the body, body is connected to core barrel inner cylinder top again after the completion of assembling.Before coring, ball pitching tool is exempted from huge discharge circulation, drilling fluid impact, and spring-compressed, drilling fluid is flowed into from piston mouthful, by the metering orifice on flow righting disc, passes through core barrel inner cylinder and drill bit；When coring, small displacement is used instead, when ball pitching tool is exempted from drilling fluid impact, spring does not compress, and drilling fluid only flows through the bleeder of return connector without flow through ball pitching tool is exempted from, then by the annular space between core-extracting toolsinternal barrel and outer barrel.
The advantage of the invention is that：One is that tool construction is simple, when contained spring fails, changes parts simple；Two be safe and reliable, without worrying that dismantling drilling rod input steel ball produces potential safety hazard.
Brief description of the drawings
Fig. 1 is that one kind is cored with exempting from ball pitching tool assembling schematic diagram；
Fig. 2 is body part structural representation in Fig. 1；
In figure：1st, piston, 2, spring, 3, body, 4, flow righting disc, 5, metering orifice, 6, bleeder, 7, return connector.
Embodiment
Referring to the drawings 1, one kind is cored with exempting from ball pitching tool, including return connector 7 and the bleeder 6 being arranged on return connector 7, hollow body 3 is connected in one end of return connector 7, piston 1 and spring 2 are set in body 3, and the bottom connection traffic righting disc 4 of body 3, the periphery of flow righting disc 4 is provided with metering orifice 5, wherein piston 1 is sealed with the open top of body 3 and coordinated, and spring 2 is located between piston 1 and flow righting disc 4.
Referring to the drawings 2, the body 3 assumes a " convex " shape structure, and its ledge is connected with the internal thread of return connector 7.The tapered structure of piston 1, the open top of body 3 that cooperation is sealed therewith is the conical surface of same gradient.The quantity of metering orifice 5 of bleeder 6 and the periphery of flow righting disc 4 on return connector 7 is 3-8；Flow righting disc 4 is connected by screw thread with body 3.
The present invention's cores with ball pitching tool is exempted from, and before coring, huge discharge circulation, drilling fluid impacts the piston 1 for exempting from ball pitching tool, and spring 2 compresses, and drilling fluid is flowed into from piston mouthful, by the metering orifice 5 on flow righting disc 4, passes through core barrel inner cylinder and drill bit；When coring, small displacement is used instead, when the piston 1 of ball pitching tool is exempted from drilling fluid impact, spring 2 does not compress, and drilling fluid, which can not flow through, exempts from ball pitching tool, can only flow through the bleeder 6 of the return connector 7 of coring tool, again by the annular space between core-extracting toolsinternal barrel and outer barrel, then coring tool starts to core.
