New casing technology brings big benefits

This year, face low oil of severe situation, SHENGLI oilfield factory process Institute technicians for SHENGTUO oilfield wells casing damaged increasingly serious of status, concentrated research research, independent design out light tube injection wells casing protection tube column, through in reservoir above, and cement returned to high following parts added seal across device, will easy occurred casing damaged of injection layer segment above parts casing and injection parts segmentation, effective reduced injection shí water in the dissolved oxygen, and high salinity and the injection velocity, on casing of damaged.

In production process in the, WINS mining process by technicians found in used repair tubing finished wells shí, distribution water device, and sank sand late ball, Wells xià tool often due to rust scale, impurities jam and failure, injection validity up not to this class wells 3-5 years validity of requirements, only in full wells application new anti-corrosion tubing to guarantee its tube column validity, which led to has single wells cost sharply rose, only tubing a items will more inputs 80,000 yuan around.

In order to not increase cost of single well and  achieve light tube injection wells casing of effective protection, the process technicians light tube injection wells casing protection tube column for optimization, innovation developed out has set pressure type ball sat, replaced has original tube column in the of distribution water device and sank sand late ball, easy jam of tool, formed has only by seal across device and set pressure ball sat composition of no throttle, and big channel injection tube column. The tube column in seal across device zhī xià wells segment used repair tubing, does not due to jam and makes tube column failure, not only so, new developed of set pressure ball sat its structure simple, costs more sank sand late ball and distribution water device compared to single wells can save 2000 Yuan, by measuring, and full wells used new tubing of casing protection tube column compared to, average single wells can save job costs 93,000 yuan.

At present, the string in shengli oil extraction factory applied 12 times, have maintained a steady injection of State,only this small technical cumulative cost savings of more than 1 million Yuan, completely solve the restrictive oldcasing protection tubing high cost problems.http://sinorigs.net/

Sand control techniques of samll Casing in shengli oilfield

In the current dire circumstances of low oil prices, full use of the existing old oil field, shengli oilfield casing wells resources, meticulous research, scientific rational layout design, a number of side-tracked, implement overhaul in new measures such as tapping the potential of remaining oil in mature oilfields has become important, Eor, savings bonds effective means.

Casing in shengli oilfield oil well sand control techniques, as the oil production plant of "Twelve-Five" during the major scientific research projects. At present, the oil field there are small casing wells 78, including trades the small casing sidetracking wells, overhauled wells. In recent years, this oil field technicians for small sand casing technical difficulties of the Institute, after tireless research, evolved for different reservoir types and different sand control technique of series of well conditions.

Dongying on the one hand small span of mechanical sand control technology of sand well matching mode. First, for different casing diameter, formed has PFS filling tool series, can meet minimum diameter for 82 mm small casing of anti-sand needs; second, in quartz sand specifications and around silk screens design aspects, on quartz sand specifications, and around silk screens od and the sieve sewing size for has optimization, both guarantee has oil sets ring empty has must of radial thickness, and meet has anti-sand hòu small rushed tube anti-cycle flush fish cavity processes, improve has ring empty block sand wall of reliability; addition in construction process shàng, according to different reservoir features and wells condition conditions, Hermetic filling processes, such as filling, reverse circulation, through optimization of construction parameters such as displacement, sand-carrying more than, an effective solution to the ring space "bridging" risks, improve the reliability of a sand barrier.

Is the multiple layers, on the other hand sand control technology in large span well layered model. First, developed success achieved has different casing diameter layered construction seal across device series, site practice proved, the series seal across device seat seal reliable, and bearing pressure level high, completely can meet site construction of requirements; second, construction process take paint sand layered pre filling, and low concentration resin "sealing" construction process, guarantee has near wells block sand barrier has high strength; addition, through theory calculation, obtained different shot hole way and wells diameter conditions xià wells theory mining liquid strength, for further extended anti-sand validity lay has based.

At the end of March, casing wells in shengli oil field this year have been implemented little mechanical sand control in 3 wells, paints sand-resin sand 4 + times, success rate of 100%, technological measures efficiency of 92.7%, has been increased to more than 1200 tons of oil. Casing the well sand control technology is getting more mature, victory has become of increasing oil production plant processes, measures of tapping "weapon".
