Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] Such as figure 1 It is a structural diagram of the semantic ontology library of the present invention. The stage of semantic encapsulation of oilfield data includes ontology analysis, ontology design, and ontology establishment. With the participation of domain experts, an initial sensor ontology is constructed in this stage, that is, to realize the most basic concepts and main relationship modeling of sensors and their observations, which is the basis of the ontology processing stage.

[0048] Ontology analysis: to obtain domain knowledge, the main sources of ontology knowledge are document information in the sensor field, expert knowledge and reusable ontology. At this stage, you should try to list all the concepts that the system wants to state or explain to the user.

[0049] Ontology design: To organize the structure of a large ...

Abstract

The invention relates to a semantics based oil well indicator diagram measuring method. The semantics based oil well indicator diagram measuring method comprises the steps of firstly semantically packaging data information of an oil well, and then performing indicator diagram oil gauging based on the semantically packaged data. Due to introduction of a semantic technology, an indicator diagram oil gauging system provides a standard noumenal interface to a user, so that more users with limited computer knowledge can visit the indicator diagram oil gauging system, configuration becomes simpler and more convenient and operation becomes easier when the indicator diagram oil gauging system is used; on the other hand, as the mode of analyzing the indicator diagram is adopted to measure the yield of the oil well, the original oil gauging mode of performing manual routing inspection for the oil well and measuring with a need of stopping the well is avoided. Therefore, the well does not have to be stopped while the manpower resource is saved, and the oil production efficiency of the oil well is increased indirectly.

Description

technical field [0001] The invention relates to the technical field of oilfield output measurement, in particular to a semantic-based oil well work diagram measurement method. Background technique [0002] As a non-renewable resource, oil has irreplaceable strategic significance for the country's politics, economy and military. China's oil security problem is serious, and there are some major risks and challenges: With the sustained, stable and rapid development of my country's economy, oil consumption continues to grow, crude oil demand continues to rise, and the gap between oil supply and demand has an increasing trend, which has gradually become a constraint One of the important factors of my country's economic development. As of the end of 2009, PetroChina's proven remaining recoverable reserves were 2.79 billion tons, and the reserve-production ratio of remaining recoverable reserves was 14.8. However, among these remaining recoverable reserves, the quality of oil resou...
