油气井效益评价及其分类

油气井效益的高低直接影响到油气开采企业效益的好坏，以前油气井效益评价及其分类研究或多或少存在分类指标不明确、分类不完全等问题。为此，以油气井生产成本和费用的不同范围（层次）的归集为基础，建立相应的油气井效益评价模型，按效益值的大小将油气井分为高效益井、效益一类井、效益二类井、边际效益井和负效益井5类。油气井效益评价方法简单、实用、易操作，分类思路清晰、分类含义清楚，为科学评价油气井生产经营状况提供了依据。

Benefit evaluation and classification of oil and gas wells

The degree of benefit in oil and gas wells will have direct effect on the profit of oil and gas exploration companies. The previous studies related to the benefit assessment and classification of oil and gas wells have shown their weak points more or less in the clarity and integrity of classification methods. Therefore, based on the production cost attributed to different costs and expense levels, the corresponding benefit evaluation models are built respectively for oil and gas wells, by which 5 types of wells with high benefit, benefit Ⅰ, benefit Ⅱ, marginal benefit, and negative benefit are thus classified. This benefit evaluation method by these different models is simple, practical and easy to use with clear thinking and definition in benefit classification, providing robust foundation for scientific and reasonable evaluation of the production of oil and gas wells.
