Du 84 Raoyang River Reservoir Development Law And Supporting Technology Research

This text resumptively introduced the present development condition of the super dense oil in Dawn Oil-field. From the aspects such as structure characteristic, sediment characteristic, deposite characteristic, fluid property, distributing characteristic of oil and water, stratum stress, temperature, and etc., this text detailedly introduced the geologic characteristics and special character of the super dense oil in Du 84 Raoyang River Oil-field. According to a great deal of statistical data, we systemically studied the exploitive characteristic and the take +in and out characteristic of vertical and level oil well. And we analyzed the restrict facters which influence the in and out effect of oil well, according to geologic parameter, infuse gas technics parameter, shoot bore, and etc.,provided scientific gist for pass in and out of oil well in the future. Aimed at the questions in the pass in and out process,such as the short period in producing, the low rate of circle adopting water, containing sand, steam fleeing, unbalanced employing of oil layer etc., we analyzed these reasons in detail,and by inosculating the fectual yielding conditions at the same time, we invent some new suited technics,such as chemistry-aid eduction, fasten sand in high temperature, defend sand by manual well-wall, temporary plug in high temperature, using mud adjust section etc., and scientifically appraised the mechanism of new suited technics and effects of actualizing. The result of spot application indicates, this study has aggressive leading function for the exploitation of super dense oil in Dawn oil-field. Not only the using effect of suited technics is obvious, but also the constructing technics is simple and the cost is low. All these characteristics are suited for the need of exploiture in Du 84 Raoyang River oil layer.
