2.2 Piston rod strength check 2.2.1 Strength check When the piston rod is working, it is the pressure rod, and the weakest section is the cross section of the live cylinder. The inner diameter of the living cylinder is 1=78 outer diameter,=92, and the thrust is the formula for calculating the compressive stress of the rod. = 1868.3 wakes up 2. Substituting into the above formula, the compressive stress of the piston rod is ==64.2 is called =2603, so the piston rod is The strength meets the requirements.
2.2.2 The length of the stability check, here is the corresponding specification, 7412741474; the application of chemical mud in the wide area drilling v. Wenjie Industry Group's land survey, the company Shen Qingyun Zhang is now the hole collapsed The diameter is the main factor affecting the efficiency of drilling into the moon. It is also the direct cause of accidents in the hole. The two areas most affected by this are the ground super deep hole drilling underground water drilling construction.
Disperse the use of low solid phase chemical mud. Can solve these difficulties fundamentally.
1 mud preparation and function ii mud preparation material 801 plugging agent, 1.2 mud effect (1) cooling drill bit (1) carrying rock collection (3) protective plugging (4) well hydraulic hydraulic impact drilling and snail, drilling 5 slick drill from; 2 preparation Method and point 1 Bentonite is fully pre-hydrated for 24 hours. After the base slurry is prepared, it is stored for another day. The chemical properties of the mud are stabilized; 2 the optimum amount of alkali is selected.
Make a small sample according to the weight of bentonite 212. The optimal two small and medium-sized tests determined by the test are the basic principles for mastering the performance of the mud.
Determination of mud index index colloidal rate funnel viscosity specific gravity plastic viscosity initial end shear force loss amount sand content field value. The new mud is mainly palm and low in sand. City than the city. The tip is dizzy +. The degree is small. , 1 value is appropriate; specific gravity of 1.05 water loss, 130 rings. Leakage 20 is in normal drilling to create turbulence in the mud as much as possible. It is a major factor in improving drilling efficiency. It is a prerequisite for strengthening the solid control to slow down the mud and thick. If the viscosity and water loss of the double-polymerized mud rise, the colloidal stability is destroyed. The thinner iron complex salt and the fluid loss additive sodium carboxymethyl cellulose were adjusted in time to maintain their performance. Diluted mud to administer the ruling, ceremonial ceremonies, ceremonies, 蟮 嘟 考 考 考 考 考 考 考 考 考It is necessary to adjust the response indicators in time according to the drilling level. For the unstable formation of humic acid potassium, the amount of slight loss of the formation 801 blocking agent dry powder into the circulation pool is good.
3 Drilling implementation has carried out the construction of 5 ultra-deep holes, with an average hole depth of 1400 points and 1393.6. The problem is that the thick layer of conglomerate with clay rock shrinkage and muddy cement collapses. The fault zone is difficult to pass. For these questions, double-polymer mud was used separately. 10; composite loach makes 5 drill holes meet or exceed the single-machine standard of high-quality, high-efficiency and low-consumption, and the characteristics of 4å© mud, composite mud is an important means to solve the construction progress of the collapsed diameter and reduce the construction progress. Its main features are a good shear dilution å¿¡; 2 formed not thin and changed; 3 comparison, heart. In addition to rock pine; 4 has a good inhibitory effect on water-sensitive formations; 5 is simple and easy to prepare, 5 concluded that a large number of boreholes in the wells are well constructed, and it is difficult to leave the protective wall of the mud in the easy-to-shrink formation. The important role of chemical mud in sealing the wall. For the construction of drilling projects in the future, it is important to carry out the chemical slurry from single machine to centralized pulping with mud cleaning equipment such as high-frequency vibrating screen cyclone desander. Improve the utilization rate of the mud; replace the mud after the new cycle of the old mud is normal. The inertia radius of the low pressure slow speed drilling into the cross section of the pressure bar.
3 to 15, the value is substituted into the formula. The flexibility of the piston rod is = 25 34.2 = 60 into 5 is the flexibility of the 45 steel yield limit, so the piston rod is a small flexibility rod + will be unstable bending.
In order to ensure the strength of the piston rod of the main body cylinder block, a reasonable amount of cold drawing deformation is determined. To ensure that its mechanical properties are equivalent to the mechanical properties of 45 steel quenching and tempering treatment. Tested by the technical supervision department for each of the 3 tests and application effects of cold drawn 45 steel pipes from January 1999 to June 2000, in Qizhen. Liangzhuang Xiezhuang and other mines have carried out industrial tests. The test shows that the 1200 type pusher has a light weight and a large thrust. High strength and easy operation. Flexible and smooth. Good sealing performance, in line with the mining hydraulic pusher enterprise standard, the requirements of stomach 0682000, the bending effect is remarkable. No piston rods are bent. Only the piston rod has no bending items. Each pusher can save annual maintenance costs of more than 600 yuan; at the same time reduce the amount of materials, blue 1 whip, black dry view, black 3, coffee, 1 down, 0 Rui.
