已探明未动用储量的评价及经营管理方式

Evaluation of Proved Unproducing Reserves and Operating Management Mode.

目前已探明未动用储量评价的实质是新增投资的增量效益评价。常规经济评价方法无法指导各油田已探明未动用储量的开发投资决策，因此，提出了“微利开采”（增量效益评价）评价方法，并将已探明未动用储量在地质评价的基础上分为经济一类、经济二类、“微利开采’”一类、“微利开采”二类、“微利开采”暂无效益储量。还提出了采用先进、实用配套的工艺技术措施降低已探明未动用储量开发投资、成本的方法及经营管理模式，对各油田盘活已探明未动用储量资产具有深远的影响和现实意义。

At present, evaluation of proved unproducing reserves is virtually an evaluation of incremental benefits following newly-increased investments. Conventional economic evaluation methods available are unable to guide the in-vestment decision-making for development of proved unproducing reserves of each oilfield. Based on geologic evaluation, this paper presents an evaluation method named 'meager profit production''(or incremental benefits evaluation method). Based on geologic evaluation results, these reserves are divided into economic Class Ⅰ and Class Ⅱ, as well as ' meager profit production'' Class Ⅰ and Class Ⅱ that belong temporarily to non-profit reserves. In addition, the procedures for using advanced and practicable measurements to reduce investment and cost for development of proved unproducing reserves are proposed along with relevant operating management modes. These will have profound and immediate signifi-cance in activating proved unproducing reserves property. This study aims at activiting existing property, properly eval-uating probable economic benefits derived from the reserves so as to serve for making decisions of these investments in Xinjiang oilfields.
