摘要
A油田新钻的两口水平井在试油段厚度、孔洞发育状况、井眼轨迹无显著差别的情况下，日产量差异近7倍!本文在对两口井岩性、物性、污染等角度分析的基础上，认为X4井高产的主要原因是在孔洞发育的背景下钻遇了多套高角度裂缝，实现了孔洞缝的良好配置。续而本文在储层分级的基础上预测产能，并得到新井试油的验证。
There is not significant difference in thickness and porosity between 2 new horizontal wells in A oilfield,but daily yield of Well X4 is as nearly 7 times high as that of Well X7.Based on the analysis of lithology,physical property and pollution,etc.,it is found that why Well X4 has high yield is meeting with several groups of high angle fracture to realize good collocation of pores,vugs and fractures.Productivity prediction was carried out on the basis of reservoir grading and was verified by oil testing in another new well.
