Spiral drill collar can be prevented Downhole drilling tools during drilling differential pressure block, spiral grooves may allow mud flow freely around the drill collar to balance the pressure to prevent the formation of block, thereby effectively preventing differential sticking occurred. You can reduce the contact area with the drilling shaft, and thus the possibility of blocking the differential pressure can be effectively reduced. The reason why the spiral drill collars are widely used because of its own characteristics of the decision, this particular spiral drill collars to reduce the contact area between the wall and the tube, thereby avoiding "sticking" phenomenon of the drill string.

Drill collar up to nearly the number of drill collars manufacturers branches of production planning support, import and export of products up to 719, of which nearly 300 HWDP products in addition to conventional spiral heavy weight drill pipe also increase the drill pipe, drill collar large size contracts with nearly 200 Products involved in 34 varieties, tube specifications ranging from 127-255.
 In the production process, there are more than 290 branch collars on quality products with special requirements. Qualified tensile strength, impact strength required to achieve a minimum of 80 and 85 joules, -20 ℃ low temperature impact work to ensure that more than 30 joules.

Drill is an essential part of the drill drill collars manufacturers string, which is mainly used to transfer torque and transporting drilling fluid. Active drill pipe body and joints are connected together using welded method. In order to increase the strength of the joints, pipe welding ends body part is thick, thick form of internal upset, outside the thick, thick inside and outside the three.
     Narrowing the inner diameter of the pipe ends to increase the inner thickened wall thickness, which is consistent with the outer diameter of the drill pipe, the outer diameter of the joint is not too large, while the well rotary joint in contact with the borehole wall is small, wear are more small, but because the inner diameter of the thickened portion of smaller diameter than the tubular body, to increase the flow resistance of the drilling cycle.
     Inner diameter of the external upset drill pipe is the same, but the outside diameter of the tube ends of the increase, the outer diameter larger than the outer diameter of the tool joint drill with the size of the joint, increases when the well rotary joint on the wall contact friction, easy to wear; Since this is consistent with the inner diameter hole opener drilling of the drill pipe inner diameter, the cycle of drilling fluid flow with less resistance.
     Inner and outer thickened drill pipe, the inner diameter is reduced at both ends of the tubular body, the outer diameter is increased to increase the wall thickness of the ends of the tubular body. Drill this structure combines the advantages of these two structures the drill pipe.

LWD technology is the key signal transmission, roller reamers drilling it is currently widely used drilling fluid pressure pulse transmission, which is currently LWD tools commonly used method, which is to convert the measured parameters into the drilling fluid pressure pulse, with the drilling fluid circulation transferred to the ground. Its principle is shown briefly shown after the measured parameters by digitally encoded into high ("1") and low ("0"), the electrical signal, which controls the drilling fluid pulse generator mushroom head, when encoded as " 1 ", the shift mushroom head, so that drilling fluid flowing through the conical opening resistance increases, resulting in additional pressure. When encoded as "0", mushroom head down back in place, the pressure to normal. This is a positive pulse transmission system. There are similar negative pulse transmission systems, continuous-wave transmission system. Advantages drilling fluid pressure pulse propagation is economical, convenient, the disadvantage is the data transfer rate (the number of bits transmitted per second) is low. In recent years, in order to increase the transmission rate again try electromagnetic transmission technology, it is the LWD tools on the non-magnetic drill collar, between the non-magnetic drill collars and the upper pipe, there is a short section of insulation in order to contain low-frequency electromagnetic wave propagation information measured Mukai week the formation. On the ground, as a voltage difference between the rig and the ground electrode is detected. Early electromagnetic wave transmission because the signal attenuation, transmission distance is short and the high cost of commercial failure, due to technological drilling jars manufacturers improvements in recent years has begun to enter the market, the advantage is the transmission rate is not affected by fluid performance. In addition, underground storage, all data stored in underground storage, to be recovered from drilling data. The advantage is a low cost, reliable data storage. The disadvantage is that the ground can not get real-time data needed to guide drilling. For large amounts of data LWD, such as imaging logging while drilling, usually using real-time transmission and underground storage combination of approaches, key hole section using real-time transmission, while the other section with underground storage wells.

In the oil and gas exploration, development,Hydraulic Drilling jars  drilling must be carried out after logging in order to understand the situation hydrocarbon formation. However, access is always after the completion of drilling, the instrument cable into the well to measure, however, in some cases, as well gradient exceeds 65 degrees in highly deviated wells or horizontal well logging data, with Cable is difficult to put down the instrument; In addition, the wall is not good prone to collapse or blockage also difficult to obtain logs. Due to the drilling process to use drilling fluid circulation, with a broken drill cuttings, drilling fluid filtrate invasion always formation. Therefore, drilled again after logging various parameters formation just drilled strata and different. So people think that if the logging tool on the drill bit, let the drill bit long on the "eyes", while you get a variety of information while drilling formation, which is the LWD. Not only the well for any situation, especially horizontal wells may be logging, and drilling parameters and formation parameters using the measured time to adjust drill track, so that the direction of drilling along the target horizon. Since logging while drilling formation parameters obtained are just drilled formation parameters, it is closest to the original state formation, for the formation of complex oil and gas more favorable evaluation than wireline.Intelligent Drilling Robot  LWD tools on the drill collar, in addition to measuring the resistivity, sonic, neutron porosity, density and other conventional logging and some imaging logging, but also measuring WOB, torque, speed, annulus pressure drilling parameters. Since the drill bit during drilling in harsh environments, high temperatures, pressure is great, intense vibration, therefore, LWD instrument reliability is still the most important issue is the business.
