Abstract

The invention relates to the technical field of well repair operation of an oilfield, in particular to a drilling line stringing-up safety method. The method comprises the following steps of: 1, untwisting a new steel wire line before a drilling line is stringed up; 2, fixing a new hook and an old hook of a derrick at positions on two sides of the derrick, which are 2 to 2.5 m above the ground, by using a steel wire line sleeve, and opening protection plates on both sides of the new hook and the old hook; and 3, disassembling all line clips at old dead line ends of the derrick, cutting off an old drilling line at a position which is 0.5 to 1.0 m above the upper parts of the dead line clips, splitting the old drilling line at the position of 1.0 m to 1.2 m, connecting a split part of the old drilling line and the split part of a new drilling line at the position of 1.0 m to 1.2 m, and fixing the top of a joint by using a thin steel wire or a thin hemp line. By adoption of the drilling line stringing-up safety method, the drilling line can be stringed up on the ground, the hooks can be replaced, the operation process is safe, and working efficiency is high, and the defects that an operator needs to work at high altitude during the conventional drilling line stringing-up and hook replacement operation, the operation process is dangerous and the working efficiency is low are overcome.

Description

Cable-feeding safety method

Technical field:

The present invention relates to a kind of oil well repairing operation technical field, particularly a kind of cable-feeding safety method.

Background technology:

Spring, winter Hetao area wind-force stronger, large rop exercise is changed in work high above the ground, and to make risk larger, when carrying out cable-feeding to scene, oil recovery factory, changing hook operation, old large rope must be first extracted out with chain rail working rig (certainly carrying on the back handcart, electric car), high-altitude application personnel carry messenger (coir rope) in sky roof, utilize messenger carry out drawing wear newly restrict greatly, change hook operation.Such personal height operation easier risk increases, and work limitation is lower, in case of strong wind, bad weather easily cause personal height falling accident.

Summary of the invention:

The technical problem to be solved in the present invention is to provide a kind of cable-feeding safety method, the method achieves to carry out cable-feeding on ground, change hook operation, safe operation process, and operating efficiency is high.Overcome existing cable-feeding, change hook operation and need operating personnel's work high above the ground, operating process is dangerous, ineffective deficiency.

The technical solution used in the present invention is: a kind of cable-feeding safety method, and the method step is as follows:

Steel wire rope broken strength before cable-feeding of one, will newly enable;

Two, new hook and the old derrick both sides that are hooked in greatly of derrick are fixed far from 2-2.5 rice, ground steel wire loop, open new hook and old hook two side guard plate simultaneously;

Three, old for derrick dead line end rope clip is all laid down, after cutting off old large rope apart from 0.5-1.0 rice, dead line clamp top, split stock at old large rope 1.0-1.2 rice and split a burst place with new 1.0-1.2 rice of restricting greatly and be connected, and top, junction finer wire or fine cordage are fixed;

Four, working rig slowly on carry large rope, remove junction rapidly when large rope fast line junction enters old hook first pulley 1-2 rice; The new large rope of drawing is being entered new hook first pulley with old large rope on the homonymy direction in the direction of old hook first pulley, after old large rope is extracted out from old hook block, be connected and fixed along new hook first pulley opposite side direction and new rope greatly, continue to carry large rope slowly;

Five, wear that 50 tons, the 80 tons large ropes of hook enter second and third, four road pulleys all operate according to the 4th step by that analogy, guarantee cable-feeding, change hook and accurately complete;

Six, last new large rope end becomes derrick dead line end, has blocked tensiometer, has adopted the fixing clamping of six road rope clips.

The invention has the beneficial effects as follows: the present invention can carry out cable-feeding, change hook operation on ground, avoid operating personnel to carry out work high above the ground, safe operation process is reliable, and operating efficiency is high.

Detailed description of the invention:

A kind of cable-feeding safety method, the method step is as follows:

Steel wire rope broken strength before cable-feeding of one, will newly enable;

Two, new hook and the old derrick both sides that are hooked in greatly of derrick are fixed far from 2-2.5 rice, ground steel wire loop, open new hook and old hook two side guard plate simultaneously;

Three, old for derrick dead line end rope clip is all laid down, after cutting off old large rope apart from 0.5-1.0 rice, dead line clamp top, split stock at old large rope 1.0-1.2 rice and split a burst place with new 1.0-1.2 rice of restricting greatly and be connected, and top, junction finer wire or fine cordage are fixed;

Four, working rig slowly on carry large rope, remove junction rapidly when large rope fast line junction enters old hook first pulley 1-2 rice; The new large rope of drawing is being entered new hook first pulley with old large rope on the homonymy direction in the direction of old hook first pulley, after old large rope is extracted out from old hook block, be connected and fixed along new hook first pulley opposite side direction and new rope greatly, continue to carry large rope slowly;

Five, wear that 50 tons, the 80 tons large ropes of hook enter second and third, four road pulleys all operate according to the 4th step by that analogy, guarantee cable-feeding, change hook and accurately complete;

Six, last new large rope end becomes derrick dead line end, has blocked tensiometer, has adopted the fixing clamping of six road rope clips.

Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
