Abstract: The upstream sector of the petroleum industry is divided into two stages -- exploration and development. The geological reserves proven in the exploration stage only reflect the preliminary and static knowledge about the oil and gas fields. China usually makes public its exploration achievements in terms of the static geological reserves. However, this may make outsiders misunderstand the oil and gas industrial situation. In the development stage, the reserves should be produced at maximum for economic benefits on the basis of deeply understanding the dynamic state of the hydrocarbon accumulation. In addition exploration should be supplemented to verify and increase the previous knowledge about the reserves. In recent years, China’s oil and gas imports have risen with the decline of the country’s oil production. However, the proportion of the proven non-produced geological reserves to the proven geological reserves is increasingly high in the reserves table, indicating that the reserves system reflected in the current reserves table cannot entirely show the economic recoverability of the reserves. It is suggested that the reserves should be continually revised and supplemented. Particularly, it is necessary to make the more detailed and clearer specifications on identification of the oil and gas recoverability and clarification of the dynamic changes in the reserves in the development stage while completing the reserves specifications on unconventional oil and gas of the various kinds which already come under large-scale development.

摘要： 石油工业上游分为勘探和开发两个阶段，勘探阶段得到的探明地质储量仅反映了对油气田的初步和静态的认识。我国对外公布勘探业绩时多使用静态的地质储量，使业外人士对油气工业状况产生相当大的误解。开发阶段不仅要在深入认识油气储存动态的基础上，最大限度将其采出并获得经济效益，还要进行补充勘探，以验证和深化此前对储量的认识。近年来，我国石油产量下降，油气进口量日趋增大，但储量表中的探明未开发地质储量的数量和占探明地质储量的比例却日趋增大，说明目前储量表中所反映的储量体系不能充分反映储量的经济可采性。建议继续深入进行油气储量的修订补充，特别在确定油气可采性、更清晰反映开发阶段储量动态变化等方面，应有更详细明确的规定，并完成已规模开发的各种非常规油气的储量规范。
