中国石化通过高精度三维地震、逆时叠前偏移成像、地震属性分析和地震反演等技术的开发与应用,在老区精细勘探和新区勘探突破中取得了良好的效果,特别是在复杂断块精细刻画、陆相砂岩岩性油气藏识别、海相碳酸盐岩储层描述、致密砂岩储层精细预测和页岩气综合评价等方面均取得了显著成果。在取得勘探新成果的同时,中国石化油气勘探当前还面临着规模战略接替阵地不明朗、天然气勘探难度大、新增储量埋藏深和品位下降、工程技术支撑能力不足等4个方面的挑战。面对挑战和困难,在老区油气勘探中,一方面要重点发展高精度地震、油藏地球物理等技术,不断提高复杂地质体识别描述精度,提高复杂油气藏评价可靠性;另一方面要开展高效环保物探技术攻关,创新性地应用装备制造、信息技术、计算机技术等新成果,降低勘探投入成本,提高勘探效率。在新区新领域油气勘探中,要进一步深化地震基础理论研究,探索复杂条件下地震信号的激发与接收规律;强化物探技术创新,着力攻克极复杂地表和地下条件下地震采集技术难关,提高低信噪比地区地震资料品质,为油气发现提供更强有力的技术支撑。
By the development and application of high-precision seismic,reverse-time migration,seismic attributes analysis and seismic inversion,etc,SINOPEC has achieved good results in the fine exploration at mature oilfields and exploration breakthroughs in new areas,especially in fine characterization for complex faulted blocks,continental sandstone lithologic reservoirs identification,marine carbonate reservoir characterization,tight sandstone reservoir detailed prediction and shale gas comprehensive evaluation,etc.However,some challenges exist in the hydrocarbon exploration for SINOPEC,including unidentified scaled strategic replacing resources,difficult in natural gas exploration,deep-buried and lower-grade new added reserves,and engineering techniques lacking in supporting seismic exploration.Facing the challenges and difficulties,in the hydrocarbon exploration of mature oilfields,on the one hand,we should focus on the development of high-precision seismic,reservoir geophysical techniques,continuously improve the identification and characterization precision of complex geological bodies,and strengthen the reliability of complex reservoir evaluation;on the other hand,we should carry out the research of high-efficiency environmental protection geophysical techniques,innovatively apply equipment manufacturing,information technology,computer technology,reduce the hydrocarbon exploration costs.In the hydrocarbon exploration of new areas,the basic seismic theory research should be deepened to explore the shooting and receiving rule for seismic signals in complex exploration areas;the innovation of geophysical technology should be strengthened,especially on overcoming the seismic acquisition technical problems at the areas with extremely complex surface conditions and subsurface conditions,to improve the quality of seismic data with low S/N,and prove powerful technical support for hydrocarbon discovery.
