榆林气田南区气藏开采中的地质因素分析
|
摘要
研究了榆林气田南区各生产井的生产动态。根据研究结果,把该区20口生产井按实际生产能力与设计方案的关系分成了3类:超过设计方案的井、达不到设计要求的井和与设计相符的井。分析了出现这3种情况的地质因素,对产能较低的井提出了增产措施。通过对比分析各种等值线图,研究了榆林气田南区的生产特征以及地质因素对产能的影响,对榆林南区压力、产量变化中所出现的地质问题进行了研究。
In this paper, the study of production development for each production well has already been performed in southern area, Yulin gas field. Based on the results, the total 20 production wells should be classified into 3 types, the wells are of that actual production capacity exceed, under, and match with the designed project. Necessarily, the geological factors of causing these situations are analyzed; furthermore, for the wells, which have the lower production capacity, the measurements to improve them should be taken. Meanwhile, contrasted and analyzed different kinds of equivalent figures to study the impaction of production characteristics and geological factors on the production capacity, as well as the study of the geological problems appearing along with the variation of pressure and production quality, are also carried out in southern area, Yulin gas field. The results will provide more detailed materials and technical references to develop this well area effectively.
