在油田开发晚期,为了恢复低产非自喷井的生产,使其保持设计的产油量,就必须对其采取专门的有效措施。为此,可用液面恢复曲线研究这类油井,也可用侧向和微侧向测井对其潜在产能进行预测,确定油层的近井地带性能,为正确设计油井的增产处理工艺提供可靠的依据。为了获取油层近井地带性能的详尽资料,俄罗斯最近成功研制了用液面恢复曲线研究低产暂闭井,及其用侧向和微侧向测井的低产非自喷井潜在产能预测方法。采用该预测方法可以精确地确定低产井地层近井地带状态,从而可据此为低产井设计和制定有针对性的、有效的增产处理措施,提高低产井的产能和油田的最终采收率。
In the late stage of oilfield development, in order to resume the production of low-yield non-self-propelled wells so as to keep the designed oil yield, special and effective measures must be taken for them. For this reason, the oil recovery curve can be used to study such wells, but lateral and micro-lateral logging can also be used to predict the potential productivity and determine the performance of near-well zones in oil reservoirs, so as to provide a reliable basis for correctly designing the stimulation process of oil wells . In order to obtain detailed information on the performance of near-well zones in the oil zone, Russia has recently successfully developed a method for predicting the potential capacity of low-yielding temporary wells with surface recovery curves and their potential yield in low-yield, non-self-injection wells using lateral and micro-lateral logging. The prediction method can accurately determine the status of near-wellbores in low-yielding formations, so that targeted and effective stimulation measures can be designed and formulated for low-yield wells to improve the productivity of low-yield wells and the ultimate oil recovery.
