摘要:
针对CB油田现阶段水平井含水上升快、产量递减迅速等日益突出的问题,通过对该油田30口水平井出水特征的深入分析,建立以水平井含水率与无因次累计产油量变化曲线形态来判别出水规律,归纳出4种曲线类型,并结合油藏类型、驱动方式分析其成因。在此基础上明确了水平井出水特征及影响因素,影响因素包括油藏开采阶段、水平段位置、储层非均质性、采液强度和出砂状况,并提出针对性控水措施,为同类型油田水平井控水稳油对策的制定与水平井优选优化提供依据。
Abstract:
Aiming at the growing problems of rapid water-cut increasing and oil production declining in CB Oilfield,analyzing characteristics of water breakthrough of 30 horizontal wells,a method was established to describe water breakthrough rule by curve pattern of dimensionless cumulative oil production changing with water-cut.Thus,four types of curves were summarized.Combined with reservoir type and driving means,the causes were analyzed.On this basis,the major influence factors of water breakthrough characteristic for horizontal well,including reservoir exploitation phase,horizontal section location,reservoir heterogeneity,liquid producing intensity and sand production conditions were clearly defined,which can provide an important guidance for making countermeasures for stable oil production and water control and optimizing design of horizontal wells in similar reservoirs.
