Its technical scheme is: this instrument is by top connection, last drainage district, vortex bead, vortex groove, lower drainage district and lower joint. Tool body opens has the central runner that is used for the empty drilling fluid circulation of inner ring, and the top connection adopts connector thread to be connected with other drilling tools with the lower clutch. Vortex bead and vortex trench are the drainage district in tool body middle part, vortex bead upper end, and the lower extreme is the district of drainage down. It is the lower clutch for top connection, lower drainage district lower extreme to go up drainage district upper end. The utility model discloses can be used to slide among drilling operation and the compound drilling operation, can effectively promote the annular space fluid to the ability of carrying of detritus, also have certain effect to driving deposit detritus on the wall of a well under the well simultaneously.
Description
Technical field
The utility model relates to the mechanical hydraulic double acting landwaste carrying implement for improve the standard well section and lower curved section landwaste carrying capacity in a kind of Oil and Gas Exploration Drilling operation.
Background technology
In petroleum gas and geological drilling, along with some special well track wells such as horizontal well, high angle hole are more and more used, the series of problems being carried difficulty initiation by landwaste also constantly presents.Particularly in horizontal well drilling process, this kind of phenomenon is very obvious, can drop to shaft bottom under gravity multiple broken by bit weight, and then carried away by drilling fluid relative to bulk landwaste in peupendicular hole at landwaste.Net horizontal section landwaste constantly can be deposited on the lower borehole wall after distance drill bit one segment distance, along with increasing of assembling, form the landwaste packed structures such as obvious cutting bed, frictional resistance is crept in the lighter's increase, severe one brings out the accidents such as bit freezing, is to be badly in need of in drilling engineering avoiding and the problem solved.
Improve the carrying capacity of drilling fluid by additionally increasing downhole tool, cost is very high and larger to bottom hydraulic energy loss; Adjustment drilling fluid system can improve the carrying capacity of drilling fluid, but property of drilling fluid on borehole wall stability, creep into frictional resistance impact larger, not easily at will change, therefore pass to the mechanical energy of drill string and the hydraulic energy of outer annular space drilling fluid itself by rotary drilling turntable, the carrying capacity improving landwaste is a kind of simple, efficient embodiment.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of novel mechanical fluid power double acting landwaste carrying implement, carries problem with the landwaste solved in the special well track wells such as existing level well, high angle hole.
In order to achieve the above object, the technical scheme that the utility model adopts is: the utility model mechanical hydraulic double acting landwaste carrying implement, is made up of top connection, upper drainage district, flow-disturbing fin, flow-disturbing groove, lower drainage district and lower contact.It is characterized in that: have in tool body for the logical central flow channel of interior annular space drilling liquid flow, top connection and lower contact adopt joint screw thread to be connected with other drilling tool; Flow-disturbing fin and flow-disturbing slot are in the middle part of tool body, and flow-disturbing fin upper end is upper drainage district, and lower end is lower drainage district; Upper end, upper drainage district is top connection, lower end, lower drainage district is lower contact.The transitional region of upper drainage district and top connection is designed with in drainage district domatic, and the transitional region of upper drainage district and flow-disturbing fin is designed with drainage district Caused by Sloping Surfaces.The transitional region of lower drainage district and lower contact is designed with lower drainage district Caused by Sloping Surfaces, and the transitional region of lower drainage district and flow-disturbing fin is designed with in lower drainage district domatic; Flow-disturbing fin and flow-disturbing groove are alternately distributed along in tool body circumference.
Compared with prior art, the advantage had and effect are the utility model: 1) this instrument can realize external annular space drilling liquid flow to change, make its from axial direction flow become the hand of spiral flow; 2) flow-disturbing fin except have change drilling liquid flow to function except, fragmentation can also be rolled to the landwaste being deposited on the lower borehole wall, and the landwaste layer that thickness is thicker is stirred; 3) adopt integral design, strengthen the structural strength of instrument.
Accompanying drawing explanation
Fig. 1 is the structural representation of mechanical hydraulic double acting landwaste carrying implement;
Fig. 2 is the cross sectional representation at mechanical hydraulic double acting landwaste carrying implement flow-disturbing fin place.
In figure, 1 top connection; Domatic in drainage district on 2; Drainage district on 3; Drainage district Caused by Sloping Surfaces on 4; 5 flow-disturbing fins; 6 flow-disturbing grooves; Domatic in 7 times drainage districts; 8 times drainage districts; 9 times drainage district Caused by Sloping Surfaces; 10 lower contacts; 11 central flow channels.
Detailed description of the invention
As shown in Figure 1, the utility model mechanical hydraulic double acting landwaste carrying implement, is made up of top connection (1), upper drainage district (3), flow-disturbing fin (5), flow-disturbing groove (6), lower drainage district (8) and lower contact (10).It is characterized in that: have in tool body for the logical central flow channel (11) of interior annular space drilling liquid flow, top connection (1) adopts joint screw thread to be connected with other drilling tool with lower contact (10); Flow-disturbing fin (5) and flow-disturbing groove (6) are positioned in the middle part of tool body, and flow-disturbing fin (5) upper end is upper drainage district (3), and lower end is lower drainage district (8); Upper drainage district (3) upper end is top connection (1), lower drainage district (8) lower end is lower contact (10).Upper drainage district (3) is designed with domatic in drainage district (2) with the transitional region of top connection (1), and upper drainage district (3) is designed with drainage district Caused by Sloping Surfaces (4) with the transitional region of flow-disturbing fin (5).Lower drainage district (8) is designed with lower drainage district Caused by Sloping Surfaces (9) with the transitional region of lower contact (10), and lower drainage district (8) is designed with domatic (7) in lower drainage district with the transitional region of flow-disturbing fin (5); Flow-disturbing fin (5) and flow-disturbing groove (6) are alternately distributed along in tool body circumference.
When this instrument uses, according to position and the well segment length of landwaste possibility deposition into wells section, this instrument is evenly installed according to certain distance interval in String relevant position, realizes the conbined usage of multiple instrument, make to reach maximum to the carrying capacity of landwaste.In combined drilling operation, due to the rotation of rotating disk, whole String will be driven to rotate, and this instrument also will rotate with drill string.Due to the impact of self gravitation, to lie under well on the borehole wall under this instrument, along with continuous rotation, flow-disturbing fin (5) rolls fragmentation by the landwaste be deposited on the lower borehole wall, stir the landwaste being piled into bed simultaneously, to be carried under the effect of the landwaste stirring the borehole wall under rear disengaging annular space drilling fluid outside and to continue to migrate forward.In addition, along the tool body alternatively distributed flow-disturbing fin (5) of circumference and flow-disturbing groove (6), can change outer annular space drilling liquid flow to, become the hand of spiral from flowing vertically to flow, the landwaste be deposited on the lower borehole wall upwards carries and makes it depart from the lower borehole wall by the drilling fluid after break-in, and then migrates forward along with the flowing of drilling fluid is carried.Therefore, this instrument also can be used in slide drilling operation.
