At last, the comprehensive treatment countermeasures to the blow sand disaster were studied, and the conclusion was that: the measure of sand consolidation by planting, sand consolidation by chemical ways and the engineering sand-proofmethod were integrated applied complementarily so that it could serve the purpose of comprehensively controlling the sand.
overpass the experimentation research result, the feasible step is brought forward to father water quality, the eligibility ratio is entireness achieving water quality standard of low filter oil field.
Some preventative and redemial measures to be undertaken are suggested as follows: ① to treate the new injection wells for clay stabilization, to use surfactant solution to improve the permeability demaged;
In order to control the severe situations, such as unbalanced advance of steam in plane and section, hot water breakthrough in partial intervals, l. l% of rate of oil production, 0.12 of oil-steam-ratio, and continuous descending of development index at early stage of steam drive in Qigu formation heavy oil reservoir in District N0.9 of Karamay oilfield, shutting in well, intermittent of steam injection, extending the tubing, added steam stimulation before steamdrive, and plugging have been successfully int...
For a water flooding oilfield, interwell tracer method as a important oil reservoir engineering means, has gained rapid development and extensive application in recent years. It can feedback many reservoir informations such as heterogeneity of oil bearing formations, distribution and flowing features of injection water etc.. Since 1994, it has been under gone the experiment and application in more than 80 well groups of Zhongyuan oil field, and obtained better application efficiency. Its operational techno...
Renqiu Buried Hill Reservoir is a double-media, bottom water, and mass ive carbonate reservoir. It has quite well-developed fracture and karst cave, an d has very high oil production at the initial stage. At the high stable producti vity and earlier decline periods, many stable production stimulation are used th at mainly include drilling adjustment well, water block and water shutoff in ord er to control bottom water coning into the well. Some integrate measures are use d at the rate quick decline period....
