葡萄花油田合理沉没度界限研究

THE STUDY OF THE SUBMERGENCE DEPTH FOR PUTAOHUA OIL FIELD

为保证抽油泵正常工作 ,达到抽井机井供采协调、高产稳产、节能降耗的目的 ,从最大产量、最高经济效益、最小泵效三个方面讨论了葡萄花油田合理沉没度 ,得出该油田单井的合理流压为 2 .5～ 3 .3MPa ,合理沉没度为 30 0～ 35 0m。确定油井工作制度时应该考虑经济效益。合理的沉没度在保证抽油泵正常工作的同时 。

Oil well pump normal working, water supply and oil production harmony, high and steady oil production, and energy-saving and consumption reducing must be guaranteed. To achieve the above goals the reasonable submergence depth of Putaohua oil field is investigated from three aspects respectively the highest production, the highest economic benefit and the lowest pump efficiency. It is found that the flowing pressure value is from 2.5 MPa to 3.5 MPa , and reasonable submergence depth is from 300 m to 500 m. When determinating the work system of oil wells, the economic benefit is always considered in a priority. Reasonable submergence depth control may guarantee the oil well pump working normally, meanwhile the highest production and the highest economic benefit are also guaranteed.
