bearing for oil drilling FAQS

QWhat does BEARING FOR OIL DRILLING have?

AOil field special bearings include mud bearing, rotary table bearing, swivel bearing and crown block bearing. Mud bearing 24052ca / c3w33, 3506 / 381 / C9, nfp6 / 723.795q4/c9-1 Special bearings for large oil fields: The two category: 666.75q228/600q228/666.75q92984q929/558.8q929/660.4q928/508q928/660.4q1032980h Class III: 3003736ca / w330003740ca / w330003760ca / w334053172k The seven category: 5795297860979602099717220977936k209748k209752k37941k37951k37961k The eight category: 50081 / 67090081889168164916818491681 / 50091681 / 60091681 / 7501681 / 8009168 2 / 8001687 / 5601687 / 6501689 / 5201689 / 620

QWhat are THE CHARACTERISTICS OF THE CYLINDRICAL ROLLER BEARINGS?

A1. The roller and raceway are in line contact or repair line contact, with large radial bearing capacity, suitable for bearing heavy load and impact load. 2. Small friction coefficient, suitable for high-speed, limit speed close to deep groove ball bearing. 3. N-type and nu type can move axially, which can adapt to the change of relative position between shaft and shell caused by thermal expansion or installation error, and can be used as free end support. 4. The processing requirements for the shaft or seat hole are high. After the bearing is installed, the relative deflection of the outer ring axis shall be strictly controlled to avoid contact stress concentration. 5. The inner or outer ring can be separated for easy installation and removal.

QHow does FRACTURING work?

AAfter the oil well production reaches a certain stage, the productivity and permeability decrease. In order to enhance the oil drainage capacity and increase the oil well production, people invented the fracturing technology. There are two kinds of fracturing methods: hydraulic fracturing and high-energy gas fracturing. Hydraulic fracturing is to inject the fluid into the well at high speed by means of the high-pressure pump truck group on the ground, and to fracture the reservoir rock by means of the high pressure held up at the bottom of the well. In order to prevent the pressure drop and the fracture self closing after the pump truck stops working, sand several times higher than the density of the formation is mixed into the injected fluid after the formation fracture, which enters the fracture together with the fluid, and stays in the fracture permanently, and the supporting fracture is in the open state, so that the oil flow environment can be improved for a long time. At present, the hydraulic fracturing technology has been very mature, and the effect of oil well stimulation is obvious, which has already become the preferred common technology. Especially for the oil flow channel is very small, that is to say, the effect of increasing production of the reservoir with lower permeability is particularly outstanding.

QWhat is MUD PUMP BEARINGS?

AMud pump bearing is one of the important parts of mud pump. It is also a general term for a wide range. Different regions, habits, and pump types involved are different in selection. Mud pump is an important equipment in drilling engineering. Its main function is to carry high-pressure mud with cuttings into the well during drilling, according to the fault characteristics of relevant bearing parts, so as to realize the fault. Purpose of diagnosis.
