Top drive device and top drive vehicle introduction

Top drive drive technology is also a drilling process. Since its introduction, the top drive has been gradually accepted and adopted by the world's oil drilling industry. At present, almost all of the drilling rigs or platforms used in the shallow sea have been equipped with top drive equipment, and land drilling rigs have also been increasingly installed. Top drive equipment. The emergence of top-drive equipment has revolutionized traditional rotary drilling methods, leading to the creation of top-drive drilling methods. Its production has great significance. On the one hand, it has promoted the advancement of land drilling technology automation; on the other hand, top-driven drilling has made it possible to automate the operation of single-drilling and drilling equipment.

The top drive provides a more efficient method for rotating the drill string and rigging the drill string. The advantages of top-drive rigs are many, mainly to save time to pick up the single root, prevent the stuck drill from scratch, and can quickly drill the drill string in seconds, so as to reduce the risk of sticking and reduce the accident rate. , To ensure equipment safety and well control safety, double internal BOP can safely control the pressure inside the drill string, is conducive to the casing operation, improve the core harvest rate, reduce the number of drilling and so on.

From the perspective of the development trend of the world's drilling machinery, in order to meet the further demand for drilling automation, the downhole bit pressing device of top-drive drilling equipment will become the main direction for the development of drilling machinery in the world.

The top-drive vehicle is a special vehicle for top-drive operations. The concept of this must be very ambiguous. The following describes several dedicated top-drive vehicles. ZYT5130TDZ4 medium oil top drive truck is an oilfield special operation vehicle, which consists of top drive device, power unit, etc. It is used for drilling and repair work with drilling and repairing machine. The mass is 1250kg, and the maximum lifting load is 3200kg. Side and rear lower protection The material of the device is Q235A, and the bolt connection is adopted. The cross section of the rear lower protection device is a slot shape, the cross-sectional dimension (mm): 100×48, and the height above the ground: 510 mm. Zhongyou ZYT5120TDZ type top-drive vehicle adopts YC6J200-33 engine and has a variety of engine displacements of 4,500, 6,700, 6,700. The maximum speed is up to 90km/h and can accommodate guests. Tongshi top-drive vehicle THS5170TDZ4, manufactured by Tonghua Petrochemical Machinery Manufacturing Co., Ltd., engine model D2066LF42, side protection material Q235-A, bolted to the frame. After the protection of the assembly, and the body is connected by bolts, the cross-sectional size of 2310 × 100 × 100 (mm), 425mm height from the ground. This will not be introduced one by one here.

The types of top-drive vehicles are also numerous. According to operation methods, they can be classified into: scissor lift trucks, boom-type aerial work vehicles, and telescopic aerial platforms. The scissor lift truck has a large working height and a large load. The telescopic aerial work vehicle has a large working radius and a small load. The boom type aerial work vehicle has a moderate working height and a moderate working radius.
