Abstract

This paper presents a set of activities to reduce water cut and develop a technical solution to measure water cut: measurement of watercut, flow rates and gas-oil ratio of a well output using a mobile unit. tracer tests and conformance control operations - watercut of reacting wells within Bashkirian stage decreased by 16,6% after those operations were performed. water flow control, flow deviation and remedying production casing damages made it possible to reduce extraction of produced water and, accordingly, the cost of oil production. development of Liquid Phase Separation Device enabled alternate delivery of oil and water to the intake of downhole pump.

Abstract

The set of equipment for evacuation of wells by pumping gas out from the annulus of the well was developed to study the effect of gas on the characteristics of pumps, increase the pump’s feed rate, to reduce gas ingress into the pump and reduce wear of rod screw pumps. The influence of vacuum and pressure increase in the annulus on the dynamic level of the well was studied. The necessity of gas removal from the annular space and bottomhole well zone was substantiated.

Abstract

It was shown in [1] that the directional structure of the wellbore profile is one of the factors complicating the operation of the wells with the PCP units. It was found that the maximum inclination angle of the well in a certain way reduces the MTBF of the rods. The maximum inclination angles of the wells with the known operating time in millions of cycles (revolutions) that had experienced rod failures have been calculated with the help of dipmeter logs of the group of directional wells. The analyzed group includes PCP units with the number of pump shaft revolutions: Up to 100 min-1; 100…200 min-1; 200…300 min-1; 300…400 min-1.

Abstract

Currently the well casing is performed for different purposes: –strengthening of borehole walls in the intervals of unstable rocks;–isolation of zones of disastrous lost circulation of flushing liquid and zones of possible crossflows of formation fluid along the borehole;–separation of intervals where geologic conditions require implementation of flushing liquid with very different densities;–Separation of productive horizons and their isolation from aquifers;–formation of a reliable channel in a well for extraction of oil or pumping a fluid into the formation;–creation of a reliable foundation for installation of wellhead equipment. The cement rock behind the casing string should be sufficiently strong and impermeable, have good adhesion to the surface of a casing pipe and to the walls of a wellbore. Analysis of the complications regarding well strengthening shows that about 30% of wells contain water cut products due to incorrect determination of oil-water contact (OWC); 20% of the complications are due to the absorption of the grouting slurry and, consequently, insufficient lifting of cement mortar; interlayer crossflows account for about 25%, of complications, fluid kicks - 10% and 15% are associated with insufficient running of strings. Liquidation of interlayer cross-flows require significant costs that reach the average of 16% of the well cost (as regards the well stock of Sheshmaoil LLC), therefore the quality of well casing is of significant importance.

Abstract

During operation of oil wells with multiple pay zones having a common filter, a negative factor may occur due to the crossflow of formation fluid from the high-pressure reservoir to the low-pressure reservoir, which leads to insufficient oil production. Currently, different types of dual completion (DC) arrangement are used to operate more than two pay zones. In PJSC Tatneft, dual-lift [1-6] and single-lift units are widely used [7]. But dual-lift DC systems have drawbacks such as high costs on capital investments and maintenance. The drawbacks of a single-lift unit are the following: the high cost of upgrading, as the unit consists of two pumps of the same type and size; plunger twist-offs occur at the place of their connection; there is a difficulty in separating the cylinder depending on the productivity of the formations in case production rate of at least one of the formations changes; the unit can only operate two pay zones apart from each other.

Abstract

Presence of mechanical admixtures in the form of suspended solids (SS) causes wear of a rotor surface and, particularly, elastomer. Wear of friction surfaces leads to hydraulic head and efficiency losses of Progressing Cavity Pump (PCP) due to decrease in tightness of contact between an elastomer and a rotor. Test bech has been designed (Fig. 1) to study the effect of wear rate on head-capacity curves of PCP unit. The bench consists of the frame 1, legs 2, tank 3, pipelines 4, drive motor 5, rod 6, shut-off valves 7 and measuring tools.
