| Product Name: | Hydraulic Jet Radial DrillingTechnology |
| Product introduction: |
1.Technical Theory： Opening the Reservoir with bit parts of the casing milling. With jet bit of hose, with the aid of high pressure jet of hydraulic rock fragmentation； A process technology of drill multi- hole in oil reservoir 2.Apply （1）Well condition Within 3300m depth. Casing Grand less than P110 Casing Size 4 1/2″-7” Maximum deviation is less than 35 （2）Wellbore Condition： Casing have no obvious change, ensure the guide string assignment asks you to clean oil, under well to use the machine for general well Job treatment before wash well, and to ensure that the borehole is clean Jet operations require standing bag space （3）Apply Formation Sandstone, Carbonate, Argillaceous Siltstone, Mud shale, Coal seam （4）Applicable reservoir reservoir more than 1.5 m interlayer well developed up and down sand is not serious fault clear clear oil and gas distribution 3、Job Parameter a radial branch to the coiled tubing under (0.5) in two times borehole diameter 1 ~ 3in penetration depth 0-100 - m design temperature under 120 ℃ (up to 160 ℃), the highest pressure to 20000 psi maximum operating depth of 3300 m (successfully) solid free drilling fluid, the liquid filter below 10 um in depth of more than 2500 meters, need to use the injection head suppose single-well 4 hole, homework time 2-4 d 4、Technical Advantage Only on the oil string with a local window, small on casing damage, reservoir is not easy to collapse radial hole can be in different drilling, can undertake multi-layer construction in thick oil layer no need the rotation of the drill string and bit, reduced the occurrence of downhole complicated conditions Don't produce mud cake pollution。 short operation period, quick effect
