Investigation of non-watered oil wells exploited in the oil field Gunashli
S.D. Mustafayev PhD in Tech. Sc. - OGPD “May 28”Until now, the study of gas-lift oil wells has not been carried out completely, that is, one curve of the dependence of the oil flow rate on the flow rate of the working agent was removed and the optimal mode of operation of the well was established. The curve of dependence of the specific flow rate of the working agent (hydrocarbon gas) on the flow rate of the working agent was also constructed from this curve. We consider such a study insufficient because the optimal flow rate of gas coming from the reservoir into the well is not determined. To complete this study, the curve of the dependence of the flow rate of gas coming from the reservoir to the well on the flow rate of the working agent should also be removed.
In the article, the two gas lift wells 217 and 308 considered are non-watered wells that produce pure oil. The novelty of the article is that for the first time it is proposed to determine the optimal flow rate of gas coming from the productive board into the well. The dependence curve Qo=Qo(Vg) should be constructed with 5–7 points and most of these points should be located on the left side of point C, which has the maximum oil flow rate, the other two points should be on the right side of point C. Half of the points on the left side must be in part AB and the other half in part BC in order to accurately determine the position of B. The well must work exactly at point B; however, it is difficult to achieve this; the actual work takes place around point B.
If all the proposed research operations are not performed qualitatively, it is also possible to get positive results.
