Abstract

The invention belongs to the technical field of petroleum drill and exploitation, relates to a key device for well cementation operation, and in particular relates to an all-hydraulic well cementing truck. The all-hydraulic well cementing truck is characterized in that a ride engine is taken as a power source and a hydraulic system is used for driving a hydraulic motor so as to drive devices such as a high-pressure plunger pump to act. Compared with a traditional well cementing truck utilizing the ride engine and a torque converter as main power outputs, the all-hydraulic well cementing truck is simple in structure, more flexible in overall layout, novel and reasonable in design, low in cost and simple to control, and the all-hydraulic well cementing truck is wider in output flow range because the high-pressure plunger pump is capable of realizing stepless speed change; the all-hydraulic well cementing truck is capable of meeting the requirements of various different operations.

Description

technical field [0001] The invention belongs to the technical field of oil drilling and relates to key equipment for well cementing operations, in particular to a fully hydraulic cementing vehicle. Background technique [0002] Cementing operation is in the oil field construction operation, in order to strengthen the well wall, ensure continuous drilling, isolate oil, gas and water layers, ensure layered oil testing during exploration and reasonable oil and gas production in the whole production, for this reason, Insert high-quality steel pipes, and fill the wellbore and steel pipe annulus with cement. In order to complete the cementing operation, it usually requires a variety of special equipment to work together. Generally speaking, ash trucks (used to transport dry cement), tank trucks (used to store and transport fresh water), cement trucks (used to inject cement slurry into wells), technical casing and production casing are usually required. [0003] There are many ty...
