孤岛油田东区对井网加密调整的必要性、调整原则、调整方案进行了论证,制定了以纵向上和平面上动用差与厚油层层内剩余油为主要挖潜对象的进一步加密调整方案。并应用油田实际资料从单井和区块的主要开发指标,对加密调整试验效果进行了综合分析。认为调整效果较好,为整个东区及油藏类型、井网条件、开采状况相似的油藏进一步加密调整提供了方法和依据。
The necessity of adjustment of well pattern, adjustment principle and adjustment plan are discussed in the East of Gudao Oilfield, and a further encryption adjustment program is formulated, which takes the residual oil in the poor and thick reservoir layers in the vertical and horizontal directions as the main tapping potential. Based on the actual data of oilfields, the author makes a comprehensive analysis of the effect of encryption adjustment test from the main development indexes of single well and block. It is considered that the adjustment effect is good, which provides the method and basis for the further east-west reservoir and the reservoir type, well pattern and reservoir condition with similar mining conditions.
