浅析油气井产能的影响因素

为准确评价和分析钻井、完井、防砂和增产措施等作业环节对油气井产能的影响，对试井解释计算出的总表皮进行了有效分解，并给出了分解后各作业环节引起的表皮系数的计算方法。通过实例计算，定量分析了影响油气井产能的因素，其中射孔、钻井污染和防砂三个作业环节是影响油气井产能的主要因素，为钻井、完井、防砂和增产过程的评价提供了一定的指导意义。

ANALYSIS ON EFFECTS ON OIL AND GAS WELL PRODUCTIVITY

The paper detailed analyzes the various effects on well productivity in drilling, completion, sand control and stimulation of production well and so on, suggests that total skin factor from well testing should be effectively divided into several parts, presents calculation method of the skin factors. By example calculating, this paper analyzes that the factors which affected the well productivity. And this paper proposes that the perforation, completion and sand control during different operations are the main factors of them. It is proved that these factors are benefit for the evaluation of drilling, completion, sand control and simulation of production well.
