七里村油田水平井开发工艺影响因素分析

Analysis of Influencing Factors of Horizontal Well Development Process in Qilicun Oilfield

七里村油田水平井开发产量变化范围大,规律不明显。为了提高水平井产量,进一步优化水平井工艺,从水平井长度、压裂液用量、压裂缝条数、支撑剂用量、压裂缝间距等因素展开影响因素分析。整体上水平井长度、压裂液用量、支撑剂用量、压裂缝间距对产油量有明显影响,水平井长度和压裂缝间距与产油量成反比,压裂液用量和支撑剂用量与产油量成正比;而压裂缝条数对产油量影响不明显。

The oil production of horizontal wells in Qilicun Oilfield varies widely and has no obvious law.In order to improve the oil production rate of horizontal wells and further optimize the technology of horizontal wells,the influencing factors were analyzed from the factors of horizontal well length,fracturing fluid,number of crimping strips,amount of proppant,and spacing between fracturing fractures.On the whole,the length of horizontal well,the dosage of fracturing fluid,proppant and fracture spacing have obvious effects on oil production,the length of the horizontal well and the spacing between the fracturing fractures are inversely proportional to the oil production,and the amount of fracturing fluid and the amount of proppant are proportional to the oil production.However,the number of fractures does not have a significant impact on oil production.
