摘要
为实现大洼油田洼38块蒸汽吞吐井网加密调整,对蒸汽吞吐加密井极限油藏条件进行了分析,得出了不同井距井蒸汽吞吐周期间产油量、平均日产油、油汽比的递减规律;利用加密时油层压力与采出程度和累产油的关系曲线,回归出了不同时期加密井产量计算公式,并对不同区块、不同时期加密并动态计算方法及相应的经验公式进行了改进和验证;在此基础上,对蒸汽吞吐废弃油藏条件进行了预测。
In order to adjust steam soak infill well pattern in Block Wa 38 in Dawa Oilfield, limiting reservoir conditions in steam soak infill wells are analyzed, oil production, average daily production and rules of oil and gas ratio decline are established between the periods of steam soaking in wells of different well space. The correlation curves of reservoir pressure and ratio of total oil produced of OOIP and accumulated oil production are used to regress the calculating equations for production at different periods of infill well. Dynamic calculating methods and corresponding empirical equations for infill wells of different blocks at different periods are improved and proven. On the basis described, the conditions of abandoned reservoir for steam soak are predicted.
