利用油藏规模序列法预测大庆西部最终可探明储量

Final Proved Reserves Evaluation of Western Daqing by Using Oil and Gas Pool Scale Sequence Method

大庆西部油气勘探已经历50多年,油气勘探程度高。应用油藏规模序列法对该区资源量进行了评价,结果表明:大庆长垣以西油气聚集区仍有477个22×104t级地质储量以上的待发现油藏,剩余资源总量达43965.3×108t。待发现油藏的规模不仅局限于百万吨以下的小规模油藏,200万吨级以上的油藏还有43个,地质储量20545.2×104t。应用油藏规模序列法所计算的大庆长垣以西油气聚集区剩余资源量及其规模分布能够为该地区今后的勘探工作及开发规划工作提供指导。

Oil and gas exploration of western Daqing has experienced more than 50 years, and oil and gas exploration degree is high. The paper presents the reserves evaluation by using oil and gas pool scale sequence method, and the result shows that there are 477 of undiscovered oil and gas pool above 22×104t geological reserves, and the gross remaining resource is 43965.3×10St. In the undiscovered oil and gas pool, there are 43 oil and gas pools above 2 million ton, their geological reserves is 20545.2×104t. The reserves scale and distribution evaluation can guide the future exploration and development in the region.
