研究油田的经济产量对优化投资结构和提高经济效益具有重要现实意义。本文把油田经济产量分解为老井经济产量、新井经济产量、措施经济产量三部分,并分别给出了计算方法。在计算老井经济产量时,采用了单井不经济产量法和油田(区块)不经济产量法两种方法,前者从生产决策的角度,根据油田生产类型的差异,通过经济极限含水率、经济极限油汽比、经济极限日产油量等可控指标来分别测度常规注水油田、热采稠油油田和靠天然能量开发油田三类油田的经济产量;后者则依据油田的投入产出情况把油田效益分为四个等级。
Studying the economic output of oilfield is of great practical significance to optimize the investment structure and improve economic efficiency. In this paper, the economic output of oilfield is decomposed into three parts: the economic output of old wells, the economic output of new wells and the economic output of measures, and the calculation methods are respectively given. In calculating the economic output of the old wells, we adopt two methods: single-well non-economic output method and non-economic output method of oil field (block). According to the difference of oilfield production types and the economic limit moisture content, Economic limit oil-vapor ratio, the economic limit of daily output and other controllable indicators to measure the conventional water injection, thermal recovery of heavy oil fields and natural energy development by the oilfield three types of oilfield economic output; the latter based on oilfield input and output The benefits of the oil field is divided into four levels.
