Circulation Problem

Many drilling problems are encountered continuously while drilling oil wells in the southern Iraqi oil fields. Many of these problems are ineffectively handled resulting in a longer non-productive time. This study aims to identify the formations such as Dammam, and Hartha formations،diagnose potential problems and provide the solution for lost circulation problem. After conducting a comprehensive study on the subject and based on available data, previous studies and some information, the managed pressure drilling (MPD) method was the best technique to solve this problem. This process may use various techniques including control of back pressures .Thus, reducing the risk and control the costs of drilled wells, which have narrow pressure window by managing the wellbore pressure profile.  The well plan software program provided by Halliburton Company was used, this software is based on a database and data structure common to many of Landmark’s drilling applications. Mud used with  various injection rates  to choose the rate that provides the conditions to achieve the best drilling process, as it using mud weights of (8.8 -8.7 ) ppg  and applied a surface back pressure (50 psi). Depending on specifications of second hole the optimal injection rate was chosen using the (hydraulics) program. As a results, rate of water injection (850) gpm, is the best  which it  provides a good efficient cutting transport ratio (CTR), which means high  stability and preventing formation damage in addition to controlling in  mud losses

Rheology Property

Vicious or severe loss mainly refers to total or complete lost circulation which occurs in fractured or cavity formation and requires repeated particulate materials or cementing slurry sealing，which is a major technical problem accompanied by drilling engineering. The special gel is an association polymer with good rheology property designed to cure severe lost circulation, which can form a type of reversible supramolecular structure(dynamic physical molecular network, rather than chemical cross-linking) by the intermolecular force of supramolecular. The gel has good shear-thinning property which can provide the gel be pumped and flow in pipes easily and flow with high viscosity and resistance in the zone porous. And the gel has visible viscoelasticity that the gel have high displacement efficiency to cut off the connection between the formation fluid and the drilling fluid in borehole. And the gel is hard to be diluted by formation fluids for its apparent viscosity and strong cohesive force. Therefore, the gel is potential to control severe lost circulation accompanying with water zones or overflow and loss coexist. In field application, the gel was successful to deal with several severe loss complexities in Sichuan and Changqin oil fields in China.
