对构造进行了研究,在原有地震反射构造图的基础上,利用新完钻井资料对原构造图进行了校核,根据实钻资料对原构造图进行了修改。进行了地层分层和对比研究,主要根据岩性及测井资料,进行了地层的小层划分和对比。开展了伏龙泉气藏储层评价,进一步加深气藏地质认识。采取动静态结合的方法对气井的产能进行了分析,开发效果评价以及气水分布特征研究。针对平面及纵向储量动用差异,采取井间加密及外围扩边两种方式提高平面储量动用程度,通过措施补层对动用程度低、动用差的层提出合理的措施方案。
The structure was studied. Based on the original seismic reflection map, the original structure map was checked by using the new drilling data. The original structure map was modified according to the actual drilling data. Stratigraphic stratigraphic and comparative studies were carried out. Based on the lithology and logging data, stratigraphic subdivision and contrast were carried out. Fulongquan reservoir evaluation carried out to further deepen the gas reservoir geological understanding. The production capacity of gas wells is analyzed by dynamic and static methods, and the evaluation of development effects and the research on gas-water distribution characteristics are carried out. In view of the difference of utilization of plane and vertical reserves, two methods are used to increase the utilization of plane reserves, such as interwell encryption and peripheral expansion, and reasonable measures are put forward by means of action stratification to the low utilization and poor utilization layers.
