摘要
针对胡39东块油藏投入开发后普遍呈现初期产能高、含水上升快、产量递减迅速等问题,运用底水锥进机理研究,认为该油藏大部分油井的实际产液量大于临界产液量,造成油井过早的见水,油藏采收率降低;其次胡39东块油藏出砂严重,套管易受损,通过射孔密度及出砂机理研究,寻找保护套管、减缓锥进和防砂的几点措施,从而达到该油藏高效开发的目的。
Aiming at the problems appears as the initial input generally present high production capacity,water content rising high,production decline rapidly in Hu 39 east block reservoir,applying bottom water coning mechanism,the research has been carried on,which shows that the practical fluid quantity is greater than the critical fluid production in most of the wells,causing the early water content,reducing oil recovery rate.Secondly Hu 39 east block reservoir with serious sanding,casing easy damage,through the perforating density and the sand production mechanism,we find some measures as protective casing and slow coning and sand control in order to achieve efficient development of the reservoir.
