摘要
油田开发的市场化决定了油藏经济开发模式研究的必要性。经济开发决策因子研究是在不同油价下 ,根据极限油汽比与产油量的关系 ,确定出经济极限油汽比、单井经济界限日产油量等参数。对二连油田吉 32断块经济开发决策因子的研究结果表明 ,随着油价和产油量的增加 ,极限油汽比逐渐降低 ,但降低幅度逐渐减小 ;在高产油量条件下 ,极限油汽比对油价的敏感程度相对于低产油量条件下较小 ;考虑经济因素 ,油田最终采收率与油价有关。在油藏数值模拟研究的基础上 ,进行了吉 32断块合理转换开采方式的研究 ,认为间歇注汽为优选转换开采方式 ,预测最终采收率可比一直采用吞吐方式提高 3%左右。图 3表 3参 7(侯健摘 )
With oil field development moving into market, research on economical development model is become necessary. This paper puts forward a conception of economical development decision-making factor and its calculation method. Based on discussion of the relations among limited OSR, oil price and oil yield, parameters such as economical limited OSR, single-well daily economical boundary production rate and so on are calculated. It can be seen that the limited OSR is gradually reduced along with the increase of oil price and (or) oil output but its extent decreases. In the condition of high oil yield, the degree of limited OSR's sensitivity to oil price is rather smaller than in the condition of low oil yield. At the same time, on the basis of numerical reservoir simulation of Ji 32 fault block in Erlian oil field, continued soak production mode and rational conversion production modes are studies. Taking economical factor into account, ultimate recovery is related with oil price. Converting the current steam soaking into the intermittent steam injection is the optimum production mode; its forecasting ultimate oil recovery is increased by 3% than continued steam soaking.
