Fracturing unit for oil field exploitation

Abstract

The invention relates to a fracturing unit for oil field exploitation. The unit comprises a signal collection system, a measuring truck, a fracturing pump truck, a manifold truck and a fracturing blender truck. The measuring truck comprises a data collection and analysis system (4), a communication system (6), a controlling system (7) of the pump truck, a controlling system (8) of the fracturing blender truck and a controlling system (9) of the manifold truck. The fracturing pump truck comprises a controlling system, a motor driven device, a data sending and receiving device and a plurality of sets of fracturing pumps. The manifold truck comprises a hydraulic controlling system, a roller assembly and an automatic coiler device. The unit has the advantages that the centralized control of the fracturing pump truck, the manifold truck and the fracturing blender truck on the measuring truck is achieved through the data sharing of a local area network, and the unit improves the controlling precision and the construction safety of the equipment and the operation is convenient and simple. The unit reduces the cable connection between the trucks, and updates the controlling technique, thereby lowering the breakdown rate of the equipment and reducing the maintaining cost drastically.

Description

technical field [0001] The invention relates to the field of shale gas exploitation equipment, in particular to a fracturing unit for oilfield exploitation. Background technique [0002] Shale gas is natural gas retained in oil-generating rock formations. It is a type of "unconventional natural gas", which belongs to the same category as "coal bed methane" and "tight gas". The global shale oil and gas resources are very rich. The US magazine Oil and Gas predicts that the world's shale oil reserves are about 11 trillion to 13 trillion tons, far exceeding the world's conventional oil reserves of more than 400 billion tons. The exploitation of shale oil and gas has become an important research topic to solve the energy crisis. According to the estimates of PetroChina, China's shale gas resources may reach 45 trillion cubic meters, of which the recoverable reserves are 38 trillion cubic meters, ranking first in the world. Fracturing equipment is the main equipment for exploiti...

Problems solved by technology

Most of the imported foreign fracturing units are in the overage service stage, their effective power decreases, and the component failure rate increases, especially the control technology is backward. Each fracturing pump truck in construction transmits control and display signals to the instrument car through multi-core cables , Start and control each fracturing pump truck by setting the centralized control panel in the instrument truck. This control and display signal transmission method requires many connecting cables, and the system requires frequent maintenance.

In addition, there is no data sharing between the fracturing pump trucks, and it is impossible to control and observe all key operating parameters of the other fracturing pump trucks through the operation panel of any fracturing pump truck, which increases the number of fracturing pump trucks. coordination difficulty
