The exploitation matching technology in the special low permeability reservoir of PuCheng oilfield;

Research and application of matching technology for indigenous microorganism flooding in Dagang Oilfield

For resolving this problem, since 2000 year, the research of low pollution profile control matching technology and field applications have been done.

A quantitative model was established for the prediction of the residual wall thickness of intermediate casing.

Statistics describe that intermediate casing damages mainly consist of wellhead subsidence, connection failure, broken down or burst, deforming, etc.

Because the mud density was reduced too much when drilling the fifth spudding wellbore at one time, the intermediate casing was weared out.

Study on comprehensive techniques for good quality and super high yield of dry nursery nonglutinous rice planted after wheat;

The Comprehensive Techniques in Mutton Sheep production;

In view of the status of limited application of screw pump oil production technique in shallow layer sand producing block of Jidong Oilfield with over 95% deviated wells and high kickoff point, oil production matching techniques for screw pump in deviated well are researched.

This paper summarizes the major biological characters and matching techniques for Liangyoupeijiu,analyzes and discusses the layout of suitable planting area,cultivation techniques for overcoming unfavorable conditions,arranging suitable seed production region and the best seed production season,including low temperature resistance technology for seed production.
