Description

Technical Field

[0001] The invention relates to the technical field of tight oil development in oil fields, and in particular to a fast optimization chart for tight oil deep pumping design and a use method thereof. Background Art

[0002] In order to achieve better production results, tight oil development is usually designed to be put into production after conventional fracturing. The lifting parameters are still designed according to conventional oil wells. There are many wells that are operated due to eccentric wear and rod breakage, and the pump inspection cycle is much shorter than that of conventional oil wells. For example, after the fracturing of the tight oil wells in the Fuyu oil layer, the lifting method is designed according to the design concept of the pumping wells in the Putaohua oil layer. The pump depth is designed to be 70m-100m above the top of the oil layer. Wells that have been put into production for more than one year have prominent problems of eccentric wear and rod breakage. The pump inspection cycle is 542 days on average, which is much shorter than the 1157-day pump inspection cycle of conventional oil wells, and the operating costs remain high.

[0003] After conventional fracturing of tight oil wells is put into production, wells that have been producing for more than one year have basically passed the effective period of oil increase, the liquid production has been greatly reduced, and the problems of eccentric wear and rod breakage are prominent. The concept of tight oil deep pumping is proposed. Through the design of tight oil deep pumping, the production can be increased when the liquid production is low, the optimal operating conditions of the machine mining can be ensured, and the occurrence of eccentric wear of pipes and rods and rod breakage can be reduced. This is an urgent problem that needs to be solved at present.

[0004] Through the search for relevant literature on dense deep extraction, a total of three relevant journal articles were retrieved, but no relevant patent literature:

[0005] Journal document 1: Research and Application of Deep Pumping Technology for Medium and Deep Oil Wells, from "Management and Technology of Small and Medium Enterprises". This study designed supporting processes for oil wells with a pumping depth of 2000-2400m and above, but did not provide deep pumping recommendations for oil wells with a pumping depth of 1600-2000m.

[0006] Journal Literature 2: Research and Application of Deep Pumping Technology in Jinzhou Oilfield, from Inner Mongolia Petrochemical Industry, the study gives the combination and proportion of pump rods with diameters of Φ70, Φ57, Φ44, and Φ38 when the pump hanging depth is 1100-2850m, but does not specify the type of pumping unit and specific parameters such as stroke and stroke frequency, which cannot meet the design requirements of deep pumping of dense oil.

[0007] Journal document three: Deep pumping technology for oil wells, from Petroleum Drilling and Production Technology, this document studies the combination of pump types, pumping parameters and sucker rod types for pumping depths of 2100-3500m. It only gives suggestions for using deep pumping technology for oil wells with a dynamic liquid level below 1800m, a pump efficiency below 20%, and insufficient fluid supply diagnosed on the dynamometer diagram. This cannot meet the design requirements for deep pumping of tight oil. Summary of the invention

The method for using a fast optimization chart for deep pumping design of tight oil according to claim 1 is characterized by: The lifting parameter items are located in the sixth ring; the lifting parameters are 3m, 4n / min, and 3m, 6n / min; the lifting parameters are 3m, 4n / min, which are respectively set in the first quadrant of the front part; and in the second and third quadrants of the rear part; the lifting parameters are 3m, 6n / min, which are respectively set in the first quadrant of the rear part, and the second and fourth quadrants of the front part.

6. The method for using a fast optimization chart for deep pumping design of tight oil according to claim 1 is characterized by: A rotatable arrow line is set from the center point to the circumference of the disc. The arrow line passes through the area where circular design options such as production liquid, pump diameter, pump depth, pumping unit, sucker rod and stabilizer matching, lifting parameters, etc. are staggered, which is used to clearly indicate the optimization results of underground and ground parameter design in the deep pumping stage.
