摘要
在勘探开发阶段不断深入、勘探开发难度不断增大的情况下,老井发现新储量以其具有投资少、成本低、风险小、见效快等优势而受到各方的重视。解释评价标准细化完善、测录井技术进步、采油工艺技术进步、圈闭认识深化等原因使老井发现新储量成为可能。以录井显示与测井解释"矛盾层"、录井及测井资料与试油资料"矛盾层"、平面"矛盾层"、录井显示(测井解释)与圈闭"矛盾层"、断层"矛盾层"、交会图"矛盾层"等"矛盾层"为线索,以油层与干层之间空白带、上倾尖灭带、油水过渡带、断块、油区中的"空圈闭"为重点领域,在成藏圈闭条件分析的基础上,通过完善解释标准、新老井结合纵横向对比分析、综合应用多种资料进行评价等技术方法,能够提高砂岩储集层老井寻找新储量成功率,降低老井发现新储量的成本。
In recent years, the discovery of new reserves of old wells has attracted attention. The reason is that with the further exploration and development, the difficulty of exploration and development has increased, and the discovery of new reserves in the old wells has superiorities such as less investment, low cost, low risk and quick result. Finding new reserves in old wells should be attributed to the refined interpretation and evaluation standards, enhanced well logging and mud logging technology, production technology progress and more accurate research of trap. Guided by the "contradiction layers" in mud logging display with well logging interpretation, mud logging and well logging data, mud logging display (well logging interpretation) with formation of reservoir traps, and in geologic plane, fault and crossplot, with the "empty traps" in the blank zone, updip zone, oil-water transitional zone, fault block and oilfield between oil and dry layer as key areas for old wells to find new reserves, based on analysis of conditions for reservoir forming traps, the success rate of finding new reserves in old wells in sandstone reservoirs can be enhanced by improving the interpretation standards, vertically and horizontally comparing the data of new wells and old wells and comprehensively using various data for evaluation.
