4.2 Condition of working out of XIII horizon of deposit Uzen

As of 1.01.2005г. On a deposit [42] from the working out beginning on a deposit 5935 chinks are drilled (including 12 water intaking), 98 - are registered in a category control, 1330 is liquidated.

For 2004 95 chinks, from them 79 extracting and 16 forcing chinks are drilled.

The extracting fund on the end of 2004 makes 3289 chinks, including 3203 operating chinks. Since 2000, actual drilling of new chinks advances the design: in 2002г - on 24 units, in 2003г - on 30 units, in 2004 g - on 49 units.

3093 chinks of operating extracting fund are operated by the mechanised way, gushing - 50 chinks, installations of electroimpeller pumps equip 33 chinks, screw pumps operate 27 chinks. 51 % of gushing chinks (25 units) it is necessary on XIII horizon. The out-of-operation fund makes 86 chinks. The current use factor of extracting fund of chinks as a whole on a deposit makes 0,941 and operation factor - 0,966.

The operational forcing fund has made 1206 chinks, including operating - 1123 chinks which are staying idle - 83.

Share of XIII horizon in the saved up oil recovery on 1.01.2005г. Makes - 24,4 %, XIV horizon - 38,6 %. Obvodnennost extracted production has reached 80,6 %. On layers of XIII horizon:

Rate of yield from initial balance stocks - 0,96 %,

Rate selection? From initial taken stocks - 2,14 %,

- Rate selection? From current taken stocks - 6,75 %.

Actually zakachka waters on deposit Uzen it was made since 1967, when zakachivali senomanskuju water with temperature plus 34-43°С. In 1971г. Have begun zakachku ocean water with temperature on a mouth of forcing chinks plus 7 - 20 °s.

As a whole on XIII horizon minimum saved up zakachka waters in a layer it is observable in 1 block (3692,2 thousand м3), maximum - in 9 block (29515,1 thousand м3). In 2004 least zakachano waters in layers of 1 block (358,3 thousand), most of all - in layers 9 blocks (1703,7 thousand).
