Problems solved by technology
This will not only greatly reduce the safety of the construction site, but also greatly increase the operating cost
[0005] Secondly, there are no auxiliary measures when aligning the upper oil pipe and the lower oil pipe, which will cause frequent collisions between the upper oil pipe and the lower oil pipe, which will inevitably cause damage to the male and female joints of the oil pipe, making its strength and The tightness is seriously affected, and it is very likely that the entire oil pipe will be scrapped, resulting in significant economic losses

Embodiment approach
[0052] A preferred embodiment of the plasticizer according to the present invention is as follows:
[0053] The plasticizer is mixed with diethylene glycol dibenzoate, epoxidized soybean oil, deionized water, hydrogen peroxide, and chloroform according to the mass ratio of 1:0.2-0.3:0.1-0.15:0.1-0.12:0.05-0.07 It is prepared by heating diethylene glycol dibenzoate, epoxidized soybean oil and hydrogen peroxide in a closed container to 70-75°C and sealing it for 2 hours to make it fully mixed, then adding deionized water and stirring And keep the temperature at 50-52°C, put in chloroform after standing for 1 hour, and mix well.
[0054] More preferably, the plasticizer can be prepared by mixing diethylene glycol dibenzoate, epoxidized soybean oil, deionized water, hydrogen peroxide, and chloroform in a mass ratio of 1:0.24:0.12:0.12:0.05.
[0055] (2) Mixing
[0056] Control the water temperature of the open mill at 70-75°C, put the masticated rubber on the open mill for mixin...

The invention relates to an oil tube jacking device and a method of using the same to operate. The oil tube jacking device comprises a first bracket, a second bracket and a supporting leg; the first bracket is connected to the second bracket through a main hydraulic rod and an auxiliary hydraulic rod; the second bracket is supported on the first bracket through the main hydraulic rod, and the main hydraulic rod is supported on the first bracket through the auxiliary hydraulic rod; a third bracket is further arranged in the second bracket, a fourth bracket is arranged on the third bracket, one side of the fourth bracket is hinged to one side of the third bracket, two supporting plates are arranged on the upper portion of the fourth bracket, and the two supporting plates are arranged in a reversed splay shape. With adoption of the oil tube jacking device provided by the invention, a limited operating space in the field can be utilized to the maximum extent, and no boom hoist is used, so that the cost is greatly lowered and the operating safety is improved. By virtue of an oil tube connecting method provided by the invention, a butt joint can be prevented from being damaged in an oil tube connecting process, and the connecting strength and the sealing property of the oil tube are improved.
Description
technical field [0001] The invention relates to an oil pipe jack and an operation method using the same, which is suitable for the technical field of petroleum engineering. Background technique [0002] Tubing is used to insert oil wells to draw crude oil out of reservoirs. The length of each oil pipe usually ranges from tens of meters to tens of meters, so it is necessary to connect the oil pipes for use during on-site operations. The two ends of each oil pipe are respectively arranged in the form of a male joint and a female joint. The male joint means that the screw thread is located on the outer wall of the oil pipe, and the female joint means that the screw thread is located on the inner wall of the oil pipe. When connecting two oil pipes, insert the male joint of one oil pipe into the female joint of the other oil pipe and tighten it. Since the oil pipes need to be connected, the length of the single oil pipe cannot be too short, otherwise the number of connections w...
