摘要：国际合作并购油田过程中，由于常出现各项基础资料不完备问题，致使预测水平井产能一般误差较大，有时会导致并购效益产生差异。通过研究影响水平井产能预测的“四维性”因素，即产水、脱气、出砂等在储层空间及生产时间上对产能的影响，以Joshi公式为基础，建立了生产过程初期、中后期不同开发阶段考虑脱气、出砂2种导致相对渗造率剧烈变化图素下的油藏水平并产能模型，分析了不同井底流压下各固素对水平并产能的影响，并对单因素及多因素进行了量化评价。某海外并购油田某水平井产能计算表明，不同生产阶段，本文模型与水平并常用产能模型相比计算精度提高值达34.66%，验证了其可靠性。

Abstraet: Incomplete data in merged oilfields in international cooperation may lead to significant error in predicting productivities of horizontal wells. In extreme cases, such error may lead to big difference in economic performances during merging process. In the concemed study impacts of "four-dimensional" factors including water production, de-gassing, sand production, etc. for productivity prediction of horizontal wells were reviewed in reservoir space and time, then on the base of the Joshi Equation, the model for predict-ing the productivity of horizontal wells in different production stages was built with consideration of the effect of de-gassing and sand production on dramatic changes of relative permeability, and finally the impact of various factors on the productivity of horizontal wells at different bottom-hole flow pressures was clarified, and quantitative evaluation on the impact of individual and multiple factors was performed. The new model was used to determine the productivity of some horizontal wells in a merged overseas oilfield. Compared with the conventional model, the new model can enhance calculation accuracy for up to 34.66% in productivity prediction for horizontal wells. Reliability of the model has been verified through field applications.
