Abstract

The invention relates to a connection occlusion agent for an oil extraction conical screw rod of a screw pump and a preparation method thereof. The connection occlusion agent comprises the following components in part by weight: 4 to 10 parts of white silver powder, 2 to 8 parts of copper powder, 1 to 5 parts of graphite powder, 18 to 35 parts of poly alpha olefins synthetic oil, 21 to 34 parts of diethylsilicone fluid, 4 to 16 parts of polyisobutene, 3 to 12 parts of fumed silica, 4 to 15 parts of titanium dioxide, 3 to 12 parts of teflon powder, 0.5 to 3 parts of antioxygen and 0.2 to 1 part of antirust agent. The connection occlusion agent for the oil extraction conical screw rod of the screw pump can adapt to the working environment with moderate intensity of acid, alkali and salt, has a good lubricating property, and can be used in an environment of -45 DEG C to 220 DEG C for a long time. The occlusion agent realizes the goal that a screw rod has the properties of self-lock, seal and corrosion resistance in production and operation processes, and has excellent detachability when repairing a well. After the connection occlusion agent is used in the device, the well repairing work period is shortened, and the worker labor intensity is reduced, and the maintenance cost is lowered.

Description

technical field [0001] The invention belongs to adhesive or lubricating materials, and in particular relates to a biting agent for screw pump oil extraction conical screw connection and a preparation method thereof. Background technique [0002] Screw pumps have great advantages in oil field production equipment. During workover operations, lubricating and anti-corrosion considerations need to be applied to the screw connection thread during installation, because the sucker rod connection thread is under the action of high-power torque dynamic load, causing the thread to be stuck or seized. Most of the screw rods are twisted during disassembly, and the screw rods should be cut off if there is a bite. Therefore, the workover operation period is long, the labor intensity of workers is high, and the cost of materials and man-hours are significantly increased. This is a big problem that has long been perplexed in oil production by high-power screw pumps in oil fields. Content...
