Description
Technical Field
The invention belongs to the field of oil-gas and other energy operation, relates to fixed-point cutting of a coiled tubing, in particular to a novel cutting combined ball for cutting the coiled tubing, and further relates to a cutting process utilizing the cutting combined ball.
Background
In the process of oilfield operation, special conditions sometimes occur, and the condition that the coiled tubing string is clamped in the well is the most complicated, so that the coiled tubing string is difficult to treat. The tool outer diameter is typically larger than the outer diameter of the string, and most of the stuck point is at the tool, and it is sometimes necessary to cut the string above the stuck point and then to retrieve the free-running string for further processing, chemical cutting being an ideal tool. The existing chemical cutting process needs to cut off the coiled tubing before implementing the process, and then send chemical cutting bullets into the coiled tubing through transmission equipment such as steel wires, cables and the like and then descend into the target depth. The coiled tubing cutting operation divides the whole coiled tubing into two parts, so that the respective lengths of the two parts can not meet the operation length requirement of a construction well generally.
In addition, once the coiled tubing is clamped, the coiled tubing cannot be normally unlocked, the coiled tubing needs to be cut off at the wellhead before the coiled tubing is cut above the clamping point, transmission equipment such as steel wires and cables can be lowered through the inner drift diameter of the coiled tubing with a cutting tool to complete the cutting off of the coiled tubing above the clamping point, and once the wellhead cuts off the coiled tubing, the whole disk of expensive coiled tubing is scrapped.
In addition, the inner diameter of some coiled tubing is very small, and the size of the existing transmission equipment such as steel wires, cables and the like cannot pass through the coiled tubing with the small inner diameter. Under the condition that the coiled tubing is blocked at the tool string, how to cut off the coiled tubing at the wellhead is not needed, and the coiled tubing with small inner diameter can also be cut above the blocking point, and finally the coiled tubing is smoothly lifted out, so that the field problem to be solved by operators is solved urgently.
Aiming at the problems, the invention provides a novel cutting combination ball for fixed-point cutting of a coiled tubing, which consists of a hole ball and a chemical ball. According to the method, the sizes of the hole balls and the chemical balls are selected appropriately, according to the characteristic that the coiled tubing equipment can be used for throwing balls, the coiled tubing is cut off at a fixed point by filling the hole balls and putting the chemical balls to perform chemical reaction, and therefore the whole coiled tubing is kept for continuous utilization. Meanwhile, the coiled tubing can also be applied to coiled tubing with small inner diameter. The process greatly reduces the difficulty of subsequent fishing operation and saves the fishing cost; it is particularly advantageous that extreme cases of scrapping of the entire well can be avoided.

When the chemical ball type corrosion-resistant continuous oil pipe is used, for example, the chemical ball A and the chemical ball B are respectively carried and accumulated on the hole ball through diesel oil, then clear water is pumped to completely replace the diesel oil in the continuous oil pipe with the clear water, after the water-soluble film is dissolved by the clear water in the continuous oil pipe, the chemical ball A and the chemical ball B firstly undergo violent redox reaction to decompose the chemical ball B, and then acid generated by dissolving the chemical ball A and hydrochloric acid released by decomposing the chemical ball B form a strong corrosive acid solution, so that the continuous oil pipe is corroded.
In another embodiment, the combination ball comprises chemical ball a, chemical ball B, and chemical ball C.
The chemical ball C is spherical or quasi-spherical, or swim bladder-shaped or fusiform, and the material of the chemical ball C is a known high explosive body which can be used conventionally in the field of oil and gas, such as solid gunpowder or solid explosive high explosive agents, for example trinitrotoluene (TNT), hexogen (RDX) and octogen (HMX).
The invention further relates to a novel cutting process for fixed-point cutting of coiled tubing, which is characterized by being carried out by using the cutting combination ball according to the invention, and comprises the following steps:

7) lifting the coiled tubing, and if the coiled tubing can be lifted normally, finishing the operation; if the continuous oil pipe is lifted up, the chemical ball A and the chemical ball B are repeatedly thrown in until the continuous oil pipe is cut off, and the continuous oil pipe can be lifted up normally.
In another embodiment, the novel cutting process of the present invention comprises the steps of:
1) selecting proper hole ball size and number and proper chemical ball size according to the length of the inner diameter channel of the downhole tool string and the inner diameter of the coiled tubing;
2) putting a plurality of hole balls into the inner diameter of the coiled tubing at the ball throwing position of a roller of the coiled tubing equipment;
3) after the putting of the hole ball is finished, putting the chemical ball A;
4) pumping diesel oil with one oil pipe volume, and then putting a chemical ball B;
5) pumping clean water to completely replace diesel oil in the continuous oil pipe with clean water, and dissolving the water-soluble film of the chemical ball by the clean water in the continuous oil pipe;
6) pumping clean water and then pumping chemical balls C;
7) the chemical ball A and the chemical ball B are subjected to chemical reaction on the last porous ball, and the temperature is increased by the heat generated by the reaction;
8) the chemical ball C explodes due to the increased temperature caused by the reaction of the chemical ball A and the chemical ball B, and the explosion is generated to cut off the coiled tubing at the upper part of the tool string at a fixed point;
9) trying to lift the coiled tubing, and if the coiled tubing can be lifted normally, finishing the operation; and if the lifting is not moved, repeatedly putting the steps 2) to 8) until the oil pipe is cut off and the lifting can be normally carried out.
Under the condition that the wall of the oil pipe is thick, chemical balls can be put into the oil pipe in batches for multiple times, and after the former group reacts, the next group is put into the oil pipe to increase the total amount of the corrosion chemical or generate multiple groups of high-temperature explosions, so that the cutting operation is completed.
In step 2), the shot hole balls are used for filling height, and the shot hole balls are shot in quantity based on that the total height of the stacked shot hole balls is not less than the length of the tool string inner diameter channel, and is preferably slightly more than the length of the tool string inner diameter channel.
The novel fixed-point cutting process has the advantages that: the cutting process can effectively solve the problems under the condition that various unfreezing measures are invalid when the operation tool string is blocked in the well. On one hand, after the coiled tubing at the upper part of the tool string is cut off at a fixed point, the coiled tubing can be taken out, so that the coiled tubing is prevented from being cut, and the whole coiled tubing is kept and can be continuously utilized; on the other hand, the method can also be applied to coiled tubing with a small inner diameter without any limitation. By the method, the difficulty of subsequent fishing operation is greatly reduced, and the fishing cost is greatly saved; most importantly, the extreme condition that the whole oil and gas well is scrapped is avoided.
