摘要
于奇西地区处于阿克库勒凸起北部,成藏条件较好,是塔河油区外围重要的油气勘探区。该文通过油井的生产动态分析研究区具有油稠、天然能量低、储量动用程度低的特征。针对这些开发特征提出几点对策:注水替油、催化裂解、注CO2和增加新井。在此基础上,结合研究区各井的钻井、地震和测井资料分析认为,YQ5、YQ5-1、YQ5-3X、YQ5-4、YQ3-1、YQ3-2和YQ9井具有注水加裂解剂的潜力,在地面现场条件具备的前提下也可通过注入CO2达到降粘的效果。此外,可在YQ5井区适当增加新井以提高储量动用程度。通过此次研究,解决了开发过程中遇到的难题,确保了油藏高效开发。
Yuqi west area,which lies in the north of Akekule uplift with good forming condition of hydrocarbon reservoir,is an important petroleum exploration target in the Tahe oilfield.Through analysis of well production performance,this paper has suggested some development characteristics such as oil's heaviness,low natural energy and low development degree of reserve.Considering these contradictions,several strategies are put forward to.they are water injection substituting for oil,catalytic cracking,CO_2 injection and adding new wells.Based on that,by combination of drilling,seismic and logging data of each well in study area,it is concluded that YQ5,YQ5-1,YQ5-3X,YQ5-4,YQ3-1,YQ3-2and YQ9 are the wells of water injection and catalytic cracking's potential and CO2injection's potential when ground conditions are available.Besides,to improve the development degree of reserve,new wells can be added in YQ5 well area.All in all,through the study,the difficult problems during the development of oil reservoir are solved and the development of reservoir is improved.
