Description

Technical Field

[0001] The present application relates to the technical field of drilling equipment, and in particular to a steel pipe traction and storage device. Background Art

[0002] In the prior art, when a flexible steel pipe is used as a technical method for penetrating the stratum, a roller is required to be used as a storage device for the flexible steel pipe, and the roller is used as a power source during penetration. However, during the penetration process, the steel pipe needs to pass through a guide plate to allow the steel pipe to enter the stratum. Since the power source for the penetration of the flexible steel pipe is at its end, its front end is subject to the stratum resistance and the reaction force of the straightening device, and the bent part in the middle will be further bent uncontrollably. Therefore, a guide plate needs to be installed on the periphery of the roller so that the steel pipe can move along the periphery of the roller and finally be led out at the opening in the tangential direction. However, this will also cause friction between the steel pipe and the guide plate, generating a strong reaction force, resulting in insufficient penetration power. Moreover, when the steel pipe penetrates into a deeper stratum, due to the increase in penetration resistance, the pressure between the steel pipe and the guide plate also increases, and the friction force further increases, resulting in a rapid loss of penetration power. The steel pipe bent in the middle may even break under the force of front and rear squeezing. Summary of the invention

The power module 1 close to the formation provides the power for retracting and releasing the flexible steel pipe 2, and the drum 31 is in a free rotation state, and only serves as a container for storing the flexible steel pipe 2.

The guide pulley 32 provides guidance for the flexible steel pipe 2 when it is led out, avoiding hard friction on the plane.

In order to further increase friction, the side of the arc groove contacting the flexible steel pipe 2 is also provided with a grid structure, and the friction with the flexible steel pipe 2 is increased by the grid structure. The method of providing multiple friction links 157 can ensure that when one or more friction links 157 are worn or the performance is degraded, the equipment can still operate normally, and the anti-fault ability is stronger in the face of emergencies.

[0045] Optionally, the transmission unit includes a first transmission chain 155 and a second transmission chain 156, the first friction chain 152 is sleeved on the outside of the first transmission chain 155 and fixedly connected to the first transmission chain 155, and the second friction chain 153 is sleeved on the outside of the second transmission chain 156 and fixedly connected to the second transmission chain 156; the power unit includes a first transmission sprocket 134 and a second transmission sprocket 135, the first transmission sprocket 134 is meshedly connected to the first transmission chain 155, and the second transmission sprocket 135 is meshedly connected to the second transmission chain 156. Among them, one end of the first transmission chain 155 is sleeved on the first transmission sprocket 134, and one end of the second transmission chain 156 is sleeved on the second transmission sprocket 135. The first transmission chain 155 drives the first transmission sprocket 134 to move, and the second transmission chain 156 drives the second transmission sprocket 135 to move.

[0046] In one embodiment, the first transmission chain 155 and the second transmission chain 156 each include two chains arranged side by side, each chain is formed by connecting a plurality of sub-chain links 158 in sequence, and the friction chain link 157 is fixed on the sub-chain links 158 of the two chains.

[0050] Optionally, the depth encoder 16 and the driving gear 131 are arranged on both sides of the first transmission sprocket 134. In addition, in order to achieve waterproofing, the housing of the depth encoder 16 is a waterproof sealing structure.

Through the multiple U-shaped grooves on the first plate and the second plate, the horizontal adjustment plate 12, the first sprocket 136, the second sprocket 137 and the auxiliary pulley 154 can be moved within a certain range, so that the sprocket structure that drives the friction chain link 157 to move and the horizontal distribution position of the auxiliary pulley 154 can be adjusted, thereby changing the straightening degree of the flexible steel pipe 2, so that its straightening outlet is not just simply vertically downward.

[0063] Optionally, a first opening corresponding to the first plate and a second opening corresponding to the second plate are provided on both sides of the supporting frame 11.

[0065] The U-shaped groove on the adjusting plate 12 can be used to adjust the curvature of the opposite side of the first friction chain 152 and the second friction chain 153, thereby changing the degree of straightening of the flexible steel pipe 2. Specifically, when the flexible steel pipe 2 is retracted, the adjusted flexible steel pipe 2 can be expressed as an arc, the direction of which is opposite to the winding direction of the flexible steel pipe 2 in the drum 31, that is, the steel pipe is over-straightened to a certain extent to avoid residual bending stress after the steel pipe leaves the straightening mechanism (power module 1), that is, the situation where it cannot be completely straightened. In addition, the first friction chain 152 and the second friction chain 153, which can be adjusted in shape, also provide a new operating idea, that is, when the operating space is limited, the steel pipe can be straightened in an inclined state and the steel pipe can be penetrated obliquely, so as to have better operating adaptability. Since the steel pipe is in a bent state when it is stored, it may still have a certain amount of bending residual stress after it is transmitted through the vertical straightening mechanism, resulting in the steel pipe not being vertical when it penetrates the formation. The horizontal distribution of the first friction chain 152 and the second friction chain 153 is adjusted by adjusting the adjustment plate 12, thereby changing the straightening degree of the flexible steel pipe 2, further loading the flexible steel pipe 2 in the opposite direction of the steel pipe storage bend, eliminating residual bending stress, and allowing the probe to penetrate the formation in a vertical state.

[0066] Optionally, the steel pipe traction storage device further includes a first guide member 141 and a second guide member 142.

A guide wheel is arranged on the side of the first guide member 141 and the second guide member 142 opposite to the flexible steel pipe 2. The first guide member 141 and the second guide member 142 can provide guidance for the flexible steel pipe to enter and exit the straightening mechanism.

[0067] The steel pipe traction storage device of the embodiment of the present application has the following advantages:

[0068] ① The power module 1 is placed in front to reduce unnecessary stress links of the flexible steel pipe 2 during the penetration process, avoid friction between the flexible steel pipe 2 and the steel pipe receiving module, and effectively increase the penetration performance;

[0069] ② The first friction chain 152 and the second friction chain 153 are used to transmit power, which effectively increases the contact area of ​​the clamping friction of the flexible steel pipe 2, is more stable and reliable, and the power transmission is more efficient and avoids slipping. It can also disperse the clamping load on the flexible steel pipe 2, avoid excessive single-point clamping load on the flexible steel pipe 2, and prevent the flexible steel pipe 2 from being clamped.

[0070] ③ The friction clamping transmission mode is adopted, which can straighten the flexible steel pipe 2 while actively conveying the flexible steel pipe 2, instead of pushing the flexible steel pipe 2 through the straightening device at the end to straighten the flexible steel pipe 2, thereby eliminating the reaction stress generated by the flexible steel pipe 2 passing through the straightening device and improving the penetration capacity;

[0071] ④ A depth encoder 16 is installed on the main power shaft 133, which can monitor the penetration depth in real time. The depth encoder 16 adopts an integrated design, which can be effectively waterproof and has higher reliability.
