Fault detection method of oilfield water injection pipeline network based on wireless sensor technology

Abstract

The invention discloses an oilfield water injection pipe network failure detection method based on the wireless sensing technology. The method is implemented according to the following steps: initializing the system of a computer, acquiring the topological structure relationship data of a water injection pipe network, which are acquired by data acquisition systems in advance, and storing the topological structure relationship data of the water injection pipe network into the computer in advance; installing one set of data acquisition system on each node, and initializing the data acquisition systems; acquiring the pressure and flow parameters of the water injection pipe network; performing simulating calculation through the computer; conducting failure judgment. According to the method, the data acquisition systems with ARM+Zigbee wireless modules are used for acquiring data, so that the characteristics of high speed and low cost are achieved. The manual labor intensity is reduced, and the real-time performance of data acquisition is maintained. Influence from the scale of the topological structure of the water injection pipe network is relatively smaller, and the implementation of calculation occupies fewer resources of the computer. A forward simulation algorithm is adopted, the implementation is simple, the calculating speed is high and the method is suitable for computer programming.

Description

technical field [0001] The invention belongs to the technical field of automation, and in particular relates to a fault detection method for an oilfield water injection pipe network based on wireless sensing technology. Background technique [0002] At present, oilfield water injection is the basic method of oilfield production and development, which uses water injection wells to inject water into the oil layer to supplement and maintain the pressure of the oil layer. After the oil field is put into development, with the increase of production time, the energy of the oil layer itself will be continuously consumed, resulting in a continuous drop in the pressure of the oil layer, a large amount of degassing of the underground crude oil, an increase in the viscosity, a great reduction in the production of the oil well, and even the stop of spraying and production, resulting in underground A large amount of dead oil remains and cannot be extracted. In order to make up for the u...
