Abstract

A drilling fluid has prepared of The Syrian Clay and has used  in drill of The gas and oil well in The Syrian fields. has bad Properties cause. drill operation is over cost because increase the drilling time ,when the drill operation has finished A drilling fluid is a dangerous for environment.

When adding The polymers with a drilling fluid .their Properties are best, the drilling time is less and drill operation is over economically. , when the drill operation has finished A drilling fluid has saved in special tank for next using ,it is a Environmental compatibility

This research  to aimed  for  Improvement Properties of the  Drilling Mud preparing of The Syrian Clay(Water Base Mud and Salt Mud) and has used  in drill of The gas and oil well in The Syrian fields and the laboratory evaluation adding the polymers.

At develop performance the Drilling Mud preparing of The Syrian Clay

The Syrian Clay has weak ability for controlling in The Rheological Properties (Viscosity and Yield point and Gel strength) . filter controlling . Carrying capacity. Weak ability in Cuttings removal  and Suspend them

We need to big quantity(120gr/l) of The Syrian Clay  for  preparing  Drilling Mud ,this increase solid content . reduce a rate of penetration (ROP). Increase the drilling time. Increase time execution of well. and Increase the total cost of drill a well.

The filtration quantity will is big .cause a damage  in the production formation. this require adding material for  controlling in filtration.

for Improvement Properties of drilling mud , must  reduction Syrian Clay quantity to(50gr/l) and adding The polymers (natural and synthetic) different concentrations , and measuring The Rhological Properties and filtration, evaluation results of  the laboratory experiment .finally chose the better .
