摘要:
CO2吞吐措施可提高稠油开发效益,因此,应根据候选井的地质条件和井况等指标对吞吐井进行筛选。基于相关资料及数值模拟成果,考虑油藏性质、流体特征以及水平井开采长度等指标,提出了适用于稠油油藏水平井CO2吞吐的井位筛选评价指标体系及等级划分方法,利用模糊评判理论与信息熵理论,提出了井位筛选的具体方法和步骤。根据X油藏已实施吞吐31口井的数据对所提方法进行了验证,验证结果与实际施工情况比较吻合,表明所提方法是可行的,为类似的稠油油藏采用水平井CO2吞吐提供借鉴。
Abstract:
Heavy oil exploitation benefit can be improved by CO2 stimulation process. Any horizontal well CO2 huff and puff should be selected by the geological conditions and performance of candidate wells. Combined with related data and numerical simulation results, comprehensive consideration of reservoir properties, fluid characteristics and horizontal well length, this paper put forward the horizontal well location selection evaluation index system and grading method suitable for heavy oil reservoirs by CO2 huff and puff process, and concrete approaches and steps by means of fuzzy evaluation theory and information entropy theory.31wells data of CO2 stimulation in X reservoir were used to verity the proposed method. The verification result is accordant with the actual situation, showing that the proposed method is feasible, and can provide reference and guidance for similar heavy oil reservoir development with horizontal well CO2huff and puff process
