Directional Well Service

HHOGES is wellequipped with experienced field engineers and PM personnel in directional wellservice and advanced instruments like MWD, LWD and gyroscope. It providesservices like directional well/ horizontal well/cluster well engineeringdesign, construction, manag-ement and wellbore trajectory control.

I      Instrument& Equipment

   

With sets of domestically manufactured HL-MWD instruments, two America APS HT MWDinstruments, two APS resistivity instruments and two Gyro inclinometers, wecan meet the need of construction survey service of variouswell-type at home and abroad.

II.    Technology System

    Centralized short radius control technology

    Guided drilling technology

    MWD Technology

    Casing milling and sidetracking technology

    Slim-hole technology

    Three-dimensional by pass technology

    Deep-horizontal well drilling technology

    Directional well software technology like Navigator

III.   Service Capability

We are equipped with rich experiences andgreat construction ability in design and construction of various directionalwells and horizontal wells, especially technical experiences in extended reachwells, ultra-deep wells, horizontal wells and sidetracking wells,having cooperated with various contractors at home and abroad, We have the capabilityof constructing 20 wells simultaneously.

IV.   Main Achievements  

Sidetrack drilling succeeded at first try in a 62° highly deviated well in Xinchang Gas Field.

Although the hole diameter in XinjiangKelameili Oilfield is as small as 118mm, the horizontal section aftersidetracking is 960m.

Construction of horizontal wells and extended reach wells in Tarim Oilfield with well depth of 6000-7300 m.

Construction of general horizontal wells innorthern Shaanxi Oilfield with horizontal displacement of 1200 m.

The drilling period of directional wells inPetroChina Yumen Oilfield was generall-y shortened for over 20 days, whichreached an advanced level in faster drilling technology in YaK Block.

The APS instrument is used under a welltemperature of 170 (max.) inXinjiang Region.

We have drilled well types likeextended reach wells, horizontal wells, cluster wells and sidetracking wells inoil wells, gas wells and shale wells etc.
