塔里木油田效益评价及单井经济极限研究

对油田效率进行评价，这是油田开发工作由产量主导型向效益主导型转变的重要体现，对明确投资方向、降低成本、提高油田经济效益，均具有重要的指导意义；在塔里木油田开发进入中、高含水期时，为了适应油田单井不同的地质、开发和经济条件，研制了单井经济极限产量、极限含水、措施经济极限增油量图版、这些研究为单井当前的效益分析、措施效益评价等，提供了一种灵活的查询和分析工具。

APPRAISAL OF TARIM OILFIELD PRODUCTION EFFICIENCY AND RESEARCH OF SINGLE-WELL ECONOMIC LIMITS

Appraisal of oilfield production efficiency demonstrates the critical change of oilfield development from production-oriented to benefit-oriented style, and provides valuable parameters in determining investment, lowering cost and improving oilfield economic benefits. With the en single-well's try of Tarim oilfield's produce to medium to high water cuts, according to single-well's different technical and economical conditions, this paper establishes model and chart for the present economic minimum flow rate, maximum water cut, and well-stimulation economic minimum oil increment in single-well. These results gave a convenient tool for appraisal of well production and stimulation.
