Description
Technical Field
The invention relates to the technical field of marine oil and gas drilling, in particular to a deepwater surface conduit feeding tool release simulation experiment device and method.
Background
Deep water drilling generally refers to drilling with offshore operation water depth of more than 900 meters, collapse easily occurs in the process of deep water drilling in the ocean due to the fact that the strength of a non-diagenetic stratum at the shallow part of the deep water drilling surface layer is not high, and a deep water surface layer guide pipe serves as a first layer of sleeve pipe installed in the whole deep water oil well construction process and provides structural support for all subsequent sleeve pipes and well head equipment, and is a throat of the deep water drilling.
The deepwater surface conduit jet running-in technology is a key link of deepwater drilling engineering construction, and can realize continuous drilling and feeding of multiple steps such as 'one-opening' drilling, conduit running-in, 'two-opening' borehole drilling and the like through one-trip pipe column, thereby greatly saving the operation time and cost. The deep water surface conduit feeding tool is a key tool for realizing the purpose of feeding a conduit into a surface conduit by deep water jet, and is also called as a deep water continuous drilling feeding tool because the deep water continuous drilling feeding tool has the function of continuous drilling. During use, the deepwater surface conduit feeding tool is firstly assembled with drilling tools such as a drill bit and the like, then assembled with a low-pressure wellhead head, a surface conduit and a mud pad, then lowered into a specified position of the seabed, and finally subjected to injection operation. After the deep water surface layer guide pipe feeding tool is ejected in place and mechanically connected, the releasing pin at the upper part is cut off to release the deep water surface layer guide pipe feeding tool, the mandrel is lowered down to perform 'two-way' drilling, the drill rod is lifted up after the deep water surface layer guide pipe feeding tool is drilled in place, the positioning pin between the deep water surface layer guide pipe feeding tool and the low-pressure wellhead is cut off by the lifting force, and the deep water surface layer guide pipe feeding tool is separated from the low-pressure wellhead and is recycled.
Because the internal structure and parts of the deepwater surface conduit feeding tool are very complex and are not isolated, the internal structure and the parts are matched and cooperated with each other, when the deepwater surface conduit feeding tool is released and recovered, once the pin cannot be normally sheared off in the normal construction process through a series of complex mechanical movements, the deepwater surface conduit feeding tool cannot be recovered, even a drill rod is broken, and an underwater wellhead is abandoned, so that huge economic loss is caused.
The deep water surface conduit feeding tool is complex in stress in the processes of lowering, releasing, recovering and the like, and different pins play different roles in different processes, so that the requirements on whether the deep water surface conduit feeding tool is sheared are different. For example: the positioning pin bears the weight of devices such as an underwater basal disc, an underwater wellhead, a surface guide pipe and the like in the lowering process and cannot be sheared off; the release pin bears the weight of the injection pipe column, the environment and the mechanical disturbance load in the lowering process and cannot be sheared off; in the releasing process, under the action of specific loads such as torque shearing and the like, only after the releasing pin is sheared, the mandrel is separated from the mandrel bush; in the recovery process, under specific lifting force, the positioning pin can be sheared by the lifting force, and the recovery of the deepwater surface conduit running-in tool and the jet pipe column thereof is realized. However, because of lack of corresponding simulation devices in laboratory research, accurate stress analysis, implementation and the like of the deepwater surface layer conduit feeding tool in the processes of lowering, releasing, recovering and the like cannot be effectively researched, and therefore accidents that the deepwater surface layer conduit feeding tool cannot be accurately and effectively released when the deepwater surface layer conduit feeding tool is used for carrying out surface layer conduit injection operation in the actual production process sometimes occur.

8. The deepwater surface catheter running tool release simulation experiment method as claimed in claim 6, wherein the step S2 comprises the steps of:
step S21: arranging a lifting motor device on an experiment frame (1), wherein a mandrel (401) of the deepwater surface conduit feeding tool (4) is connected with a full-thread screw rod through a coupler (6), the full-thread screw rod is meshed with a gear of the lifting motor, and the gear is arranged on an output shaft of the lifting motor;
step S22: and starting the lifting motor device, lifting the mandrel (401) of the deepwater surface conduit feeding tool (4), wherein the mandrel (401) drives the body (409) to move upwards, and shearing the positioning pin (408) and the anti-rotation pin (407).
9. The deepwater surface catheter running tool release simulation experiment method as claimed in claim 6, wherein the step S3 comprises the steps of:
and continuously lifting the mandrel (401), driving the deep water surface layer conduit feeding tool (4) to move upwards by the mandrel (401) until the lower end of the deep water surface layer conduit feeding tool is higher than the upper end surface of the low-pressure wellhead head (3), and moving out the deep water surface layer conduit feeding tool (4) to finish recovery.
