摘　　要：断块油藏油水过渡带储量丰度小,井网控制程度低,储量较难有效动用。通过研究断块油藏油水过渡带含油饱和度分布、油井产出规律,考虑经济因素的影响,提出了确定油水过渡带油井投产经济技术界限的方法,理清了油水过渡带产油能力、储量丰度等地质条件与投产经济技术界限的关系。基于实际油田特点和开发要求,建立不同条件下油井投产经济技术界限图版。该图版可以指导断块油藏油水过渡带调整井部署。Due to low reserve abundance and control degree of well pattern,it is difficult to produce effectively reserves in oil - water transitional zone of fault block reservoir. On the basis of studies on oil saturation distribution and producing law of oil wells, considering economic influencing factors, a method determining the economic and technological limits of well al- location was proposed for the oil - water transitional zone in the fault block reservoirs. Using the method,it was discussed the relationship between the economical and technological limits and the geological conditions such as oil -producing capacity and reserve abundance,and so on. Based on characteristics and development requirements of practical oilfield,the economic and technical limit charts of oil - well production were established under various conditions. The charts can provide guidance to the effective deployment of adjusting wells in the oil - water transition zone of the fault block reservoir.
