Economic Evaluation Of The Transformation Of Oilfield Surface Engineering Facilities

The economic evaluation of the oil field surface engineering facilities transformation is appraising to the status of surface facilities and scheme of renewal from the field of technology economics, offering scientific basis for the actual production decision. Undergo decades of development, some oil field surface engineering facilities wear out seriously, many oil field face the decision of facilities renewal and transformation Although the surface engineering facilities transformation project of the oil field has raised productivity, lowered costs, at the same time it cause transformation expense greater than profit because of unreasonable facilities renewal and heavy repair. Because of that, on the basis of investigating further, combining oil field production reality, the research of economic evaluation of the oil field surface engineering facilities transformation has been carried on systematically, the subject tries hard to offer the theoretical foundation for the investment decision of the facilities transformation project in the oil field. According to the needs of oil field reality and the character of the subject, the thesis has carried on thorough research from three respects of the state of facilities, renewal and heavy repair. According to the character of complicated technology, large scale and so on of, the oil field surface engineering facilities, the thesis has proceeded from production reality and set up a set of effectual oil field surface facilities status evaluation index systems, and has carried on the rational appraisal and calculation combining relevant knowledge of fuzzy mathematics, establishing the foundation of the relevant decision in the oil field. Combining the life-span of facilities and technological state of development, under the systematic research, the thesis has offered the theoretical foundation of renewal decision of facilities; At last the thesis has carried on overall research of facilities heavy repair from two respect of the technology and economy, so as to ensure after heavy repair the facilities not only reach the demand on technology but also have better economic benefits.
