Abstract
The utility model discloses a well drilling pressure device, including the pressure block, be provided with the balancing weight on the pressure block, be provided with the drilling fluid runner the same with being connected the drilling string internal diameter in the pressure block. An increasing or reduce, the structure is simpler, and convenient to use can effectually in shallow layer, the big displacement horizontal well drilling process of super shallow layer apply the weight on bit to the shaft bottom drill bit, reduces the construction operation risk that well drilling pressure device can carry out the balancing weight according to required weight.
Description
Technical field
The utility model belongs to oil and gas drilling rig technical field, is specifically related to a kind of drilling well water booster system.
Background technology
Shallow-layer, an ultra shallow layer extended horizontal well due to vertical depth shallow, horizontal movement is large, when creeping into, drilling assembly frictional resistance is large, the deadweight of straight well section inverted drill string is difficult to provide enough the pressure of the drill, in drilling process, drill bit drags pressure serious, drilling depth is slow, bit speed is very low, part well has to shift to an earlier date finishing drilling, do not reach the requirement of geological design to horizontal section length, have impact on the development effectiveness of oil reservoir greatly, therefore, in shallow-layer, an ultra shallow layer extended horizontal well drilling engineering, increase device in the urgent need to the pressure of the drill, ensure normally to creep into provide enough the pressure of the drill.
Utility model content
The purpose of this utility model is to provide a kind of drilling well water booster system, in horizontal well drilling process, effectively apply the pressure of the drill to shaft bottom drill bit, reduces construction operation risk.
The technical scheme that the utility model adopts is: a kind of drilling well water booster system, comprises pressure block, pressure block is provided with balancing weight, is provided with the drilling fluid runner identical with connecting drill string internal diameter in pressure block.
Feature of the present utility model is also:
Pressure block comprises upper link for coordinating joint to be connected with drill string and lower link, and pressure block side is provided with lifting eye, and the pressure-bearing end face of pressure block is provided with locating hole a.
Pressure block two ends are also provided with pin hole.
Be provided through the circular hole of drilling rod in balancing weight, the two ends of balancing weight are provided with the latching mechanism for installing hoisting mechanism, and the surface of balancing weight is provided with locating hole b, and the lower end of balancing weight is provided with location round key, and the side of balancing weight is provided with shedding motion.
Shedding motion comprises movable part, movable part is provided with fixed bolt hole and swivel bolt hole.
The beneficial effects of the utility model are: a kind of drilling well water booster system of the utility model, increase or the minimizing of balancing weight can be carried out according to required weight, structure is simpler, easy to use, in shallow-layer, an ultra shallow layer extended horizontal well drilling process, effectively can apply the pressure of the drill to shaft bottom drill bit, reduce construction operation risk.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
The structure of a kind of drilling well water booster system of the present utility model as shown in Figure 1, comprises pressure block 14, pressure block 14 is provided with balancing weight 15, is provided with the drilling fluid runner 6 identical with connecting drill string internal diameter in pressure block 14; As shown in Figures 2 and 3, pressure block 14 comprises upper link 1 for coordinating joint to be connected with drill string and lower link 5, pressure block 14 side is provided with lifting eye 4, and the pressure-bearing end face 2 of pressure block 14 is provided with locating hole a7, and pressure block 14 two ends are also provided with pin hole 3; As shown in Figures 4 and 5, the circular hole 12 of drilling rod is provided through in balancing weight 15, the two ends of balancing weight 15 are provided with the latching mechanism for installing hoisting mechanism, the surface of balancing weight 15 is provided with locating hole b13, the lower end of balancing weight 15 is provided with location round key 10, the side of balancing weight 15 is provided with shedding motion, and shedding motion comprises movable part 11, movable part 11 is provided with fixed bolt hole 8 and swivel bolt hole 9.
During use, pressure block 14 is connected between column lower end first drilling rod and second drilling rod, then located by positioning round orifice 12, the balancing weight 15 of needs is installed additional above pressure block 14, the gravity produced by the balancing weight 15 installed additional produces pressure straight down to pressure block 14 pressure-bearing end face 2, to drill string generation pressure straight down, thus improve the pressure of the drill.
A kind of drilling well water booster system, can carry out increase or the minimizing of balancing weight according to required weight, structure is comparatively simple, easy to use, in shallow-layer, an ultra shallow layer extended horizontal well drilling process, effectively can apply the pressure of the drill to shaft bottom drill bit, reduce construction operation risk.
